### 🏃‍♂️ FastMCP MQTT Tools ### 🏃‍♂️ FastMCP MQTT Tools
**Core MQTT Tools:**
- `mqtt_connect` - Connect to MQTT brokers - `mqtt_connect` - Connect to MQTT brokers
- `mqtt_publish` - Publish messages with QoS support - `mqtt_publish` - Publish messages with QoS support
- `mqtt_subscribe` - Subscribe to topics with wildcards - `mqtt_subscribe` - Subscribe to topics with wildcards
- `mqtt_get_messages` - Retrieve received messages - `mqtt_get_messages` - Retrieve received messages
- `mqtt_status` - Get connection and statistics - `mqtt_status` - Get connection and statistics
- `mqtt_spawn_broker` - Create embedded brokers instantly - `mqtt_spawn_broker` - Create embedded brokers instantly
- `mqtt_list_brokers` - Manage multiple brokers - `mqtt_list_brokers` - Manage multiple brokers
**Agent Coordination Tools (NEW!):**
- `mqtt_host_conversation` - **Host** a coordinated agent-to-agent conversation
- `mqtt_join_conversation` - **Join** a conversation hosted by another agent
- `mqtt_conversation_status` - Get status of active conversations
- `mqtt_list_conversations` - List all active conversations
### 🤝 Agent-to-Agent Coordination Protocol
**Solving the "Ships Passing in the Night" Problem**
When two agents try to communicate via MQTT, a common issue occurs: Agent A publishes a message before Agent B has subscribed, resulting in dropped messages. mcmqtt's coordination protocol solves this with a **host/join handshake**:
```
┌─────────────────┐ ┌─────────────────┐
│ Agent A │ │ Agent B │
│ (Initiator) │ │ (Invited) │
└────────┬────────┘ └────────┬────────┘
│ │
│ 1. mqtt_host_conversation() │
│ - Spawns broker │
│ - Waits for Agent B │
│ ────────────────────► │
│ │
│ 2. mqtt_join_conversation()
│ - Connects to broker
│ - Signals ready
│ ◄────────────────────
│ │
│ 3. Host acknowledges join │
│ ────────────────────► │
│ │
│ 4. All ready - safe to publish! │
│ ◄───────────────────► │
└───────────────────────────────────────┘
```
**Usage Example:**
```python
# Agent A (initiating the conversation):
result = await mqtt_host_conversation(
session_id="task-collaboration-123",
host_agent_id="coordinator",
expected_agents=["worker-1", "worker-2"],
timeout_seconds=30
)
# Returns only when ALL expected agents have joined and subscribed!
if result["ready_to_publish"]:
await mqtt_publish(topic=result["conversation_topic"], payload="Hello team!")
```
```python
# Agent B (joining the conversation):
result = await mqtt_join_conversation(
session_id="task-collaboration-123",
agent_id="worker-1",
broker_host="127.0.0.1",
broker_port=1883
)
# Returns only after host acknowledges and all agents are ready!
if result["ready_to_receive"]:
# Now safe to receive messages - guaranteed not to miss any!
messages = await mqtt_get_messages(topic="conversation/task-collaboration-123/main")
```
**Key Guarantees:**
- **No dropped messages** - Host waits for all agents to subscribe before publishing
- **Clear ownership** - Initiating agent always hosts the broker
- **Timeout protection** - Configurable timeout prevents infinite waits
- **State visibility** - Check conversation status at any time

```
## Core Components
### FastMCP Server
The foundation of mcmqtt is a high-performance FastMCP server that provides the Model Context Protocol interface:
```python
# Simplified FastMCP server structure
class MCMQTTServer(FastMCPServer):
def __init__(self):
self.mqtt_manager = MQTTManager()
self.broker_spawner = BrokerSpawner()
self.agent_coordinator = AgentCoordinator()
@tool
async def mqtt_connect(self, host: str, port: int = 1883):
"""Connect to MQTT broker with connection pooling"""
return await self.mqtt_manager.connect(host, port)
@tool
async def swarm_deploy(self, name: str, count: int):
"""Deploy coordinated agent swarm"""
return await self.agent_coordinator.deploy_swarm(name, count)
```
**Key Features:**
- **Async by Design**: All operations are non-blocking
- **Connection Pooling**: Efficient MQTT connection management
- **Error Recovery**: Automatic reconnection and retry logic
- **Type Safety**: Full Pydantic validation for all parameters
### MQTT Client Manager
Manages persistent MQTT connections with advanced features:
```python
class MQTTManager:
def __init__(self):
self.connections: Dict[str, MQTTClient] = {}
self.message_handlers: Dict[str, List[Callable]] = {}
self.connection_pool = ConnectionPool(max_size=100)
async def connect(self, broker_config: BrokerConfig) -> MQTTClient:
"""Establish connection with automatic reconnection"""
client_id = f"{broker_config.host}:{broker_config.port}"
if client_id in self.connections:
return self.connections[client_id]
client = await self._create_client(broker_config)
self.connections[client_id] = client
# Set up automatic reconnection
client.on_disconnect = self._handle_disconnect
return client
```
**Advanced Features:**
- **Automatic Reconnection**: Exponential backoff with jitter
- **Message Buffering**: Queue messages during disconnections
- **QoS Management**: Intelligent QoS level selection
- **Topic Wildcards**: Efficient subscription management
### Broker Spawner
Creates and manages embedded MQTT brokers on-demand:
```python
class BrokerSpawner:
def __init__(self):
self.managed_brokers: Dict[str, BrokerInstance] = {}
self.port_manager = PortManager()
async def spawn_broker(self, config: BrokerConfig) -> BrokerInstance:
"""Spawn new MQTT broker with configuration"""
port = await self.port_manager.allocate_port()
broker = MQTTBroker(
host=config.host or "localhost",
port=port,
config=config.to_dict()
)
await broker.start()
self.managed_brokers[broker.id] = broker
return broker
```
**Broker Management:**
- **Dynamic Port Allocation**: Automatic port management
- **Configuration Templates**: Predefined broker configurations
- **Resource Monitoring**: CPU and memory usage tracking
- **Graceful Shutdown**: Clean broker termination
### Agent Coordinator
Orchestrates swarms of AI agents with advanced coordination patterns:
```python
class AgentCoordinator:
def __init__(self):
self.swarms: Dict[str, AgentSwarm] = {}
self.container_runtime = ContainerRuntime()
self.task_queue = TaskQueue()
async def deploy_swarm(self, swarm_config: SwarmConfig) -> AgentSwarm:
"""Deploy coordinated agent swarm"""
swarm = AgentSwarm(
name=swarm_config.name,
agent_count=swarm_config.count,
coordination_pattern=swarm_config.pattern
)
# Deploy agents in parallel
tasks = []
for i in range(swarm_config.count):
agent_config = self._create_agent_config(swarm_config, i)
task = self._deploy_agent(agent_config)
tasks.append(task)
agents = await asyncio.gather(*tasks)
swarm.agents = agents
# Start coordination layer
await self._setup_coordination(swarm)
self.swarms[swarm.name] = swarm
return swarm
```
## Design Patterns
### Fractal Architecture
mcmqtt uses a fractal pattern where coordination patterns repeat at different scales:
```mermaid
graph TD
A[Global Coordinator] --> B[Region 1 Coordinator]
A --> C[Region 2 Coordinator]
A --> D[Region N Coordinator]
B --> E[Swarm 1]
B --> F[Swarm 2]
C --> G[Swarm 3]
C --> H[Swarm 4]
E --> I[Agent 1]
E --> J[Agent 2]
F --> K[Agent 3]
F --> L[Agent 4]
style A fill:#3b82f6,color:#fff
style B fill:#10b981,color:#fff
style C fill:#10b981,color:#fff
style E fill:#f59e0b,color:#fff
```
This enables:
- **Hierarchical Coordination**: Parent-child relationships at any scale
- **Local Decision Making**: Reduce coordination overhead
- **Fault Isolation**: Problems don't cascade across the hierarchy
- **Emergent Behavior**: Complex behaviors from simple rules
### Message-Driven Architecture
All coordination happens via MQTT messages with structured topics:
```
agents/
├── coordination/
│ ├── {swarm_id}/
│ │ ├── tasks/assign # Task distribution
│ │ ├── tasks/complete # Task results
│ │ └── health/status # Health monitoring
├── {agent_id}/
│ ├── commands/ # Direct agent commands
│ ├── status/ # Agent status updates
│ └── results/ # Agent task results
└── global/
├── announcements/ # System-wide messages
└── coordination/ # Cross-swarm coordination
```
### Container Isolation Strategy
Each agent runs in an isolated container with configurable resources:
```yaml
# Agent container specification
apiVersion: v1
kind: Pod
metadata:
name: agent-{agent_id}
labels:
swarm: {swarm_name}
role: agent
spec:
containers:
- name: agent
image: mcmqtt/agent:{agent_type}
resources:
limits:
memory: "512Mi"
cpu: "500m"
ephemeral-storage: "1Gi"
requests:
memory: "256Mi"
cpu: "250m"
securityContext:
readOnlyRootFilesystem: true
runAsNonRoot: true
runAsUser: 1000
capabilities:
drop: ["ALL"]
```
## Performance Characteristics
### Throughput
mcmqtt is designed for high-throughput scenarios:
| Metric | Single Instance | Clustered |
|--------|----------------|-----------|
| **MQTT Messages/sec** | 50,000+ | 500,000+ |
| **Concurrent Connections** | 10,000+ | 100,000+ |
| **Agent Deployment Rate** | 100/min | 1,000/min |
| **Cross-Agent Latency** | <10ms | <50ms |
### Scalability Limits
```python
# Theoretical scaling limits
class ScalingLimits:
# Per mcmqtt instance
MAX_MQTT_CONNECTIONS = 10_000
MAX_CONCURRENT_AGENTS = 1_000
MAX_BROKER_INSTANCES = 100
# Per agent swarm
MAX_AGENTS_PER_SWARM = 10_000
MAX_SWARMS_PER_COORDINATOR = 100
# Message throughput
MAX_MESSAGES_PER_SECOND = 50_000
MAX_MESSAGE_SIZE = 256 * 1024 # 256KB
```
### Memory Management
Intelligent memory management prevents resource exhaustion:
```python
class MemoryManager:
def __init__(self):
self.connection_pool = LRUCache(maxsize=1000)
self.message_buffer = CircularBuffer(maxsize=10000)
self.agent_registry = WeakValueDictionary()
async def monitor_memory(self):
"""Continuous memory monitoring"""
while True:
usage = psutil.virtual_memory()
if usage.percent > 85:
await self._cleanup_inactive_connections()
await self._flush_message_buffers()
if usage.percent > 95:
await self._emergency_cleanup()
await asyncio.sleep(30)
```
## Security Architecture
### Multi-Layer Security
```mermaid
graph TB
A[TLS/mTLS Transport] --> B[Authentication Layer]
B --> C[Authorization Engine]
C --> D[Container Isolation]
D --> E[Resource Limits]
E --> F[Audit Logging]
style A fill:#ef4444,color:#fff
style D fill:#ef4444,color:#fff
```
### Container Security
Each agent container runs with minimal privileges:
```dockerfile
# Agent container security hardening
FROM python:3.11-slim
# Create non-root user
RUN groupadd -r agent && useradd -r -g agent agent
# Install dependencies
COPY requirements.txt /tmp/
RUN pip install -r /tmp/requirements.txt && \
rm -rf /root/.cache /tmp/requirements.txt
# Copy application
COPY --chown=agent:agent . /app
WORKDIR /app
# Security settings
USER agent
EXPOSE 8080
# Read-only filesystem
VOLUME ["/tmp", "/app/logs"]
ENTRYPOINT ["python", "-m", "mcmqtt.agent"]
```
### Network Security
```python
class NetworkSecurity:
def __init__(self):
self.allowed_hosts = set()
self.rate_limiter = RateLimiter()
self.tls_config = TLSConfig()
async def validate_connection(self, host: str, port: int):
"""Validate connection against security policies"""
if not self._is_host_allowed(host):
raise SecurityError(f"Host {host} not in allowlist")
if not await self.rate_limiter.check_rate(host):
raise RateLimitError(f"Rate limit exceeded for {host}")
return True
```
## Monitoring and Observability
### Structured Logging
All components use structured logging for observability:
```python
import structlog
logger = structlog.get_logger(__name__)
async def deploy_agent(agent_config):
logger.info(
"agent_deployment_started",
agent_id=agent_config.id,
swarm_name=agent_config.swarm,
agent_type=agent_config.type,
resources=agent_config.resources.dict()
)
try:
agent = await create_agent(agent_config)
logger.info(
"agent_deployment_completed",
agent_id=agent.id,
startup_time=agent.startup_time,
health_status="healthy"
)
return agent
except Exception as e:
logger.error(
"agent_deployment_failed",
agent_id=agent_config.id,
error=str(e),
error_type=type(e).__name__
)
raise
```
### Metrics Collection
Built-in metrics for performance monitoring:
```python
class MetricsCollector:
def __init__(self):
self.counters = defaultdict(int)
self.gauges = defaultdict(float)
self.histograms = defaultdict(list)
def increment(self, name: str, value: int = 1, tags: Dict = None):
"""Increment counter metric"""
key = self._make_key(name, tags)
self.counters[key] += value
def gauge(self, name: str, value: float, tags: Dict = None):
"""Set gauge metric"""
key = self._make_key(name, tags)
self.gauges[key] = value
def histogram(self, name: str, value: float, tags: Dict = None):
"""Record histogram value"""
key = self._make_key(name, tags)
self.histograms[key].append(value)
```
## Extension Points
### Custom Agent Types
Implement custom agent behavior:
```python
class CustomAgent(BaseAgent):
async def process_task(self, task: Task) -> TaskResult:
"""Custom task processing logic"""
# Your implementation here
pass
async def health_check(self) -> HealthStatus:
"""Custom health check logic"""
# Your implementation here
pass
```
### Custom Coordination Patterns
Implement new coordination strategies:
```python
class CustomCoordinationPattern(BaseCoordinationPattern):
async def coordinate_agents(self, agents: List[Agent]) -> None:
"""Custom coordination logic"""
# Your implementation here
pass
```
### Plugin System
Extend mcmqtt with plugins:
```python
@plugin_manager.register("custom_broker")
class CustomBrokerPlugin(BrokerPlugin):
async def create_broker(self, config: BrokerConfig) -> BrokerInstance:
"""Custom broker creation logic"""
# Your implementation here
pass
```

title: "Agent-to-Agent Handshake Protocol"
description: "Solving the 'ships passing in the night' problem with coordinated agent communication"
---
## The Problem: Dropped Messages
When two AI agents try to communicate via MQTT, a common failure pattern emerges:
1. Agent A connects to broker
2. Agent A publishes "Hello, Agent B!"
3. Agent B connects to broker
4. Agent B subscribes to the topic
5. **Agent B never receives the message** (it was published before subscription)
This is the **"ships passing in the night"** problem - agents miss messages because they publish before the other party has subscribed.
## The Solution: Host/Join Handshake
mcmqtt's coordination protocol ensures **no messages are dropped** by implementing a simple but powerful handshake:
```
HOST JOINER
│ │
│ 1. Spawn/connect to broker │
│ 2. Subscribe to $coord/join │
│ 3. Publish broker_ready │
│─────────────────────────────────►│
│ │
│ 4. Connect to broker │
│ 5. Subscribe to topics │
│ 6. Publish join request │
│◄─────────────────────────────────│
│ │
│ 7. Acknowledge join │
│─────────────────────────────────►│
│ │
│ 8. Publish all_ready signal │
│─────────────────────────────────►│
│ │
▼ SAFE TO EXCHANGE MESSAGES! ▼
```
## Key Principle
**The initiating agent ALWAYS hosts.** This eliminates confusion about who spawns the broker.
## MCP Tools
### mqtt_host_conversation
Use this when **you** are starting a conversation with other agents.
```json
{
"tool": "mqtt_host_conversation",
"arguments": {
"session_id": "collab-task-123",
"host_agent_id": "coordinator-agent",
"expected_agents": ["worker-1", "worker-2", "analyst"],
"broker_host": "127.0.0.1",
"broker_port": 0,
"timeout_seconds": 30
}
}
```
**Parameters:**
| Parameter | Type | Description |
|-----------|------|-------------|
| `session_id` | string | Unique identifier for this conversation |
| `host_agent_id` | string | Your agent's unique ID |
| `expected_agents` | array | List of agent IDs that must join |
| `broker_host` | string | Host to bind broker (default: 127.0.0.1) |
| `broker_port` | int | Port (0 = auto-assign) |
| `timeout_seconds` | float | Max wait time for agents to join |
**Response (success):**
```json
{
"success": true,
"message": "Conversation ready! All 3 agents joined.",
"session_id": "collab-task-123",
"state": "ready",
"broker_host": "127.0.0.1",
"broker_port": 51234,
"broker_url": "mqtt://127.0.0.1:51234",
"joined_agents": ["worker-1", "worker-2", "analyst"],
"conversation_topic": "conversation/collab-task-123/main",
"ready_to_publish": true
}
```
### mqtt_join_conversation
Use this when **another agent** invited you to a conversation.
```json
{
"tool": "mqtt_join_conversation",
"arguments": {
"session_id": "collab-task-123",
"agent_id": "worker-1",
"broker_host": "127.0.0.1",
"broker_port": 51234,
"capabilities": ["data-analysis", "visualization"],
"timeout_seconds": 30
}
}
```
**Parameters:**
| Parameter | Type | Description |
|-----------|------|-------------|
| `session_id` | string | Session ID from host's invitation |
| `agent_id` | string | Your unique agent ID |
| `broker_host` | string | Broker host (from host's invitation) |
| `broker_port` | int | Broker port (from host's invitation) |
| `capabilities` | array | Optional list of your capabilities |
| `timeout_seconds` | float | Max wait for acknowledgement |
**Response (success):**
```json
{
"success": true,
"message": "Successfully joined conversation collab-task-123!",
"session_id": "collab-task-123",
"agent_id": "worker-1",
"broker_host": "127.0.0.1",
"broker_port": 51234,
"other_agents": ["coordinator-agent", "worker-2", "analyst"],
"conversation_topic": "conversation/collab-task-123/main",
"ready_to_receive": true
}
```
## Example: Two-Agent Collaboration
### Agent A (Initiator/Host)
```python
# Step 1: Host the conversation
result = await mqtt_host_conversation(
session_id="data-analysis-job",
host_agent_id="data-processor",
expected_agents=["visualizer"],
timeout_seconds=30
)
if result["ready_to_publish"]:
# Step 2: Safe to publish - visualizer is definitely subscribed!
await mqtt_publish(
topic=result["conversation_topic"],
payload={"type": "data", "values": [1, 2, 3, 4, 5]}
)
```
### Agent B (Joiner)
```python
# Step 1: Join using info from Agent A
result = await mqtt_join_conversation(
session_id="data-analysis-job",
agent_id="visualizer",
broker_host="127.0.0.1",
broker_port=51234
)
if result["ready_to_receive"]:
# Step 2: Now receive messages - guaranteed not to miss any!
messages = await mqtt_get_messages(
topic=result["conversation_topic"]
)
```
## Topic Structure
The protocol uses reserved topics under `$coordination/`:
```
$coordination/{session_id}/
├── broker_ready # Host publishes broker info (retained)
├── join # Agents publish join requests
├── joined/{agent_id} # Host acknowledges each agent (retained)
├── ready # Host signals all agents ready (retained)
└── heartbeat/{agent_id} # Optional: agent heartbeats
```
After handshake, conversations use:
```
conversation/{session_id}/
├── main # Primary conversation channel
├── {channel_name} # Additional named channels
└── ...
```
## Timeout Handling
If expected agents don't join within the timeout:
```json
{
"success": false,
"message": "Timeout waiting for agents. Missing: ['worker-2']",
"session_id": "collab-task-123",
"state": "timeout",
"joined_agents": ["worker-1", "analyst"],
"missing_agents": ["worker-2"],
"ready_to_publish": false
}
```
The host can then decide whether to:
- Retry with a longer timeout
- Proceed with available agents
- Abort the conversation
## Best Practices
1. **Always use coordination tools for multi-agent work** - Don't use raw `mqtt_connect` + `mqtt_publish` when coordinating with other agents
2. **Choose meaningful session IDs** - Include context like `task-{id}-{timestamp}` for debugging
3. **Set appropriate timeouts** - Network latency and agent startup time vary; 30 seconds is a safe default
4. **Check the response** - Always verify `ready_to_publish` (host) or `ready_to_receive` (joiner) before proceeding
5. **Handle failures gracefully** - Timeout doesn't mean failure; retry logic is your friend

# Fractal Agent Coordination
mcmqtt has evolved beyond simple MQTT integration into **the definitive platform for AI coordination**. Our fractal agent architecture enables you to deploy, coordinate, and manage swarms of AI agents with unprecedented scale, safety, and intelligence.
## What is Fractal Agent Coordination?
Fractal coordination is a hierarchical approach to AI agent management where:
- **Parent agents** spawn and coordinate **child agent swarms**
- Each **agent operates in isolated containers** for maximum safety
- **Real-time MQTT messaging** enables instant coordination across the network
- **Consciousness monitoring** prevents runaway behavior
- **Global infrastructure integration** allows deployment across cloud providers
```mermaid
graph TD

style A fill:#3b82f6,color:#fff
style B fill:#10b981,color:#fff
style C fill:#f59e0b,color:#fff
style D fill:#ef4444,color:#fff
```
## Core Capabilities
### 🏗️ Hierarchical Architecture
Deploy agents in parent-child relationships for complex coordination patterns:
```bash
# Deploy main coordinator
uvx mcmqtt coordinator start --id main-coord
# Spawn specialized swarms under coordination
uvx mcmqtt swarm deploy \
--parent main-coord \
--type browser-testing \
--agents 25 \
--target https://app.example.com
uvx mcmqtt swarm deploy \
--parent main-coord \
--type api-monitoring \
--agents 10 \
--endpoints api-config.json
```
### 🛡️ Container Isolation
Every agent runs in its own isolated container with configurable resource limits:
```bash
# Deploy with strict isolation
uvx mcmqtt swarm deploy \
--agents security-scan \
--count 5 \
--isolation strict \
--memory-limit 512MB \
--cpu-limit 0.5 \
--network isolated
```
### 📡 Real-time Coordination
Agents communicate via high-performance MQTT messaging:
```bash
# Agents automatically coordinate via topics:
# agents/{swarm_id}/coordination - Swarm-level coordination
# agents/{agent_id}/tasks - Individual task assignment
# agents/{agent_id}/results - Result publishing
# agents/{agent_id}/health - Health monitoring
```
### 🧠 Consciousness Monitoring
Built-in safety systems monitor agent behavior and prevent runaway processes:
```bash
# Automatic safety monitoring
✅ Agent consciousness check: Normal
⚠️ Agent-7: High CPU usage detected
🛑 Agent-12: Runaway behavior - container stopped
🔄 Agent-12: Clean restart initiated
```
## Use Cases
### Browser Testing Swarms
Deploy hundreds of agents to test web applications simultaneously:
```bash
# Test user journeys across 50 browsers
uvx mcmqtt swarm deploy \
--type browser-test \
--count 50 \
--target https://my-app.com \
--scenarios user-journeys.json \
--parallel true
```
**Benefits:**
- Parallel execution of complex user scenarios
- Real-time result aggregation
- Automatic screenshot and video capture
- Performance bottleneck detection
### API Monitoring Networks
Create distributed monitoring systems with intelligent load balancing:
```bash
# Monitor 100+ endpoints with 25 agents
uvx mcmqtt monitor start \
--endpoints api-list.json \
--agents 25 \
--frequency 30s \
--alerting enabled
```
**Features:**
- Distributed load balancing
- Automatic failover and recovery
- Real-time anomaly detection
- Custom alerting rules
### Security Analysis Teams
Coordinate security assessments with specialized agent roles:
```bash
# Launch comprehensive security assessment
uvx mcmqtt security analyze \
--target my-app.com \
--scope full \
--teams "owasp,network,social" \
--agents-per-team 5
```
**Capabilities:**
- OWASP Top 10 testing
- Network vulnerability scanning
- Social engineering assessment
- Compliance validation
## Safety & Reliability
### Container Security
Each agent runs in a hardened container environment:
```yaml
# Agent container configuration
security:
read_only_root_fs: true
no_new_privileges: true
user: 1000:1000
capabilities:
drop: ["ALL"]
seccomp: default
apparmor: enabled
```
### Resource Management
Automatic resource monitoring and scaling:
```bash
# Resource limits per agent
resources:
memory: 512MB # Hard limit
cpu: 0.5 # 50% of one core
disk: 1GB # Temporary storage
network: 10MB/s # Bandwidth limit
```
### Health Monitoring
Continuous health checks across all agents:
```bash
# Health monitoring output
🟢 Swarm Status: 48/50 agents healthy
🟡 Agent-23: Memory usage 85% (warning)
🔴 Agent-31: Unresponsive - restarting
📊 Average Response Time: 245ms
📈 Success Rate: 99.2%
```
## Deployment Models
### Local Development
Perfect for testing and development:
```bash
# Local swarm with 3 agents
uvx mcmqtt swarm deploy \
--agents local-test \
--count 3 \
--environment development
```

```bash
# Multi-cloud deployment
uvx mcmqtt swarm deploy \
--agents production-monitor \
--count 20 \
--regions "us-east-1,eu-west-1,ap-southeast-1" \
--providers "aws,gcp,azure"
```
### Hybrid Networks
Combine local and cloud resources:
```bash
# Hybrid coordination
uvx mcmqtt coordinator start \
--local-agents 5 \
--cloud-agents 15 \
--failover-strategy cloud-first
```

# Agent Swarms
Agent swarms are collections of coordinated AI agents that work together to accomplish complex tasks through parallel execution and real-time coordination. mcmqtt's swarm architecture enables you to deploy hundreds of agents safely and efficiently.
## What are Agent Swarms?
An agent swarm consists of:
- **Multiple agent instances** running in isolated containers
- **Shared coordination layer** via MQTT messaging
- **Centralized task distribution** and result aggregation
- **Health monitoring** and automatic recovery
- **Resource management** with configurable limits

```
## Advanced Swarm Configurations
### High-Performance Browser Testing
Deploy a swarm optimized for web application testing:
```bash
uvx mcmqtt swarm deploy \
--name browser-test-swarm \
--agents browser-test \
--count 25 \
--target https://my-app.com \
--config '{
"browser": "chrome",
"headless": true,
"viewport": "1920x1080",
"timeout": 30000,
"screenshots": true,
"performance_metrics": true
}' \
--resources '{
"memory": "512MB",
"cpu": "0.5",
"disk": "2GB"
}'
```
### API Load Testing Swarm
Create a distributed load testing network:
```bash
uvx mcmqtt swarm deploy \
--name api-load-test \
--agents load-tester \
--count 50 \
--config '{
"target_url": "https://api.example.com",
"requests_per_second": 100,
"test_duration": "10m",
"endpoints": [
"/api/users",
"/api/products",
"/api/orders"
]
}' \
--coordination '{
"ramp_up_time": "30s",
"cooldown_time": "15s",
"failure_threshold": 5
}'
```
### Security Assessment Swarm
Deploy specialized security testing agents:
```bash
uvx mcmqtt swarm deploy \
--name security-swarm \
--agents security-scanner \
--count 10 \
--target my-app.com \
--config '{
"scan_types": ["owasp", "ssl", "headers", "ports"],
"intensity": "medium",
"compliance": ["pci", "gdpr"],
"exclude_paths": ["/admin", "/internal"]
}' \
--isolation strict \
--network isolated
```
## Swarm Coordination Patterns
### Leader-Follower Pattern
One agent coordinates the others:
```python
# Deploy with leader coordination
swarm_config = {
"pattern": "leader-follower",
"leader_selection": "random", # or "performance", "manual"
"failover": "automatic",
"coordination_topics": {
"leader_heartbeat": "swarm/{swarm_id}/leader/heartbeat",
"task_assignment": "swarm/{swarm_id}/tasks/assign",
"result_collection": "swarm/{swarm_id}/results/collect"
}
}
```
### Worker Pool Pattern
Shared task queue with worker agents:
```python
# Deploy worker pool
swarm_config = {
"pattern": "worker-pool",
"queue_size": 1000,
"task_timeout": 30,
"retry_attempts": 3,
"load_balancing": "round-robin" # or "least-connections", "random"
}
```
### Pipeline Pattern
Sequential processing across agent stages:
```python
# Deploy processing pipeline
swarm_config = {
"pattern": "pipeline",
"stages": [
{"name": "data-collection", "agents": 5},
{"name": "data-processing", "agents": 10},
{"name": "data-output", "agents": 3}
],
"stage_coordination": "sequential",
"buffer_size": 100
}
```
## Swarm Management
### Real-time Monitoring
```bash
# Watch swarm metrics in real-time
uvx mcmqtt swarm watch my-swarm
# Output streaming:
# 2024-01-15 10:30:15 | Agent-7 | Task completed: user-journey-checkout
# 2024-01-15 10:30:16 | Agent-12 | Task started: api-stress-test
# 2024-01-15 10:30:17 | Agent-3 | Warning: High memory usage (85%)
# 2024-01-15 10:30:18 | Agent-15 | Task completed: security-scan-headers
```
### Task Distribution
```python
# Distribute tasks to swarm
mqtt_publish({
"topic": f"swarm/{swarm_id}/tasks/new",
"payload": {
"task_id": "task_001",
"task_type": "browser_test",
"target": "https://example.com/checkout",
"config": {
"user_scenario": "purchase_flow",
"test_data": "test_user_001"
},
"priority": "high",
"timeout": 60
}
})
```
### Result Aggregation
```python
# Collect results from all agents
mqtt_subscribe({
"topic": f"swarm/{swarm_id}/results/+",
"qos": 1
})
# Results format:
{
"task_id": "task_001",
"agent_id": "agent-7",
"status": "completed",
"result": {
"success": true,
"response_time": 245,
"screenshot": "base64_image_data",
"performance_metrics": {...}
},
"timestamp": "2024-01-15T10:30:00Z"
}
```
## Swarm Safety Features
### Container Isolation
Each agent runs in a secure container:
```yaml
# Agent container security
security_context:
read_only_root_filesystem: true
run_as_non_root: true
run_as_user: 1000
capabilities:
drop: ["ALL"]
seccomp_profile: "default"
```
### Resource Limits
Prevent resource exhaustion:
```yaml
# Per-agent resource limits
resources:
limits:
memory: "512Mi"
cpu: "500m"
ephemeral-storage: "1Gi"
requests:
memory: "256Mi"
cpu: "250m"
```
### Health Monitoring
Automatic health checks and recovery:
```bash
# Health check configuration
health_checks:
liveness_probe:
http_get:
path: /health
port: 8080
initial_delay_seconds: 30
period_seconds: 10
readiness_probe:
http_get:
path: /ready
port: 8080
initial_delay_seconds: 5
period_seconds: 5
```
### Runaway Detection
Automatic detection of problematic agents:
```python
# Consciousness monitoring alerts
⚠️ Agent-12: CPU usage > 90% for 5 minutes
🔴 Agent-23: Memory leak detected (growth rate: 50MB/min)
🛑 Agent-31: Unresponsive to heartbeat - terminating container
🔄 Agent-31: Clean restart initiated
✅ Agent-31: Health check passed - rejoining swarm
```
## Performance Optimization
### Batch Processing
Process multiple tasks per agent cycle:
```python
# Configure batch processing
batch_config = {
"batch_size": 10,
"batch_timeout": 30,
"parallel_execution": True,
"result_aggregation": "immediate"
}
```
### Connection Pooling
Reuse connections across tasks:
```python
# HTTP connection pooling
http_config = {
"pool_connections": 10,
"pool_maxsize": 100,
"max_retries": 3,
"backoff_factor": 0.3
}
```
### Memory Optimization
Optimize memory usage for large swarms:
```python
# Memory optimization settings
memory_config = {
"garbage_collection": "aggressive",
"object_pooling": True,
"cache_size_limit": "100MB",
"result_streaming": True # Don't keep all results in memory
}
```
## Troubleshooting Swarms
### Agent Not Starting
```bash
# Check agent logs
uvx mcmqtt swarm logs my-swarm --agent agent-7
# Check resource availability
uvx mcmqtt swarm resources --available
# Verify container image
docker images | grep mcmqtt-agent
```
### Poor Performance
```bash
# Analyze swarm performance
uvx mcmqtt swarm analyze my-swarm --metrics performance
# Check for bottlenecks
uvx mcmqtt swarm bottlenecks my-swarm
# Optimize configuration
uvx mcmqtt swarm optimize my-swarm --auto-tune
```
### Communication Issues
```bash
# Test MQTT connectivity
uvx mcmqtt swarm test-connectivity my-swarm
# Check message routing
uvx mcmqtt swarm trace-messages my-swarm --task-id task_001
# Verify topic permissions
uvx mcmqtt broker check-permissions --swarm my-swarm
```
## Best Practices
### 1. Start Small, Scale Gradually
```bash
# Begin with small swarms
uvx mcmqtt swarm deploy --count 3
# Monitor performance, then scale
uvx mcmqtt swarm scale --count 10
```
### 2. Use Resource Limits
```bash
# Always set resource limits
--resources '{"memory": "512MB", "cpu": "0.5"}'
```
### 3. Monitor Health Continuously
```bash
# Set up monitoring
uvx mcmqtt swarm monitor my-swarm --alerts enabled
```
### 4. Plan for Failures
```bash
# Configure automatic recovery
--recovery '{"max_retries": 3, "backoff": "exponential"}'
```

title: Your First MQTT Connection
description: Step-by-step tutorial for connecting to MQTT brokers and exchanging messages
sidebar:
order: 1
---
# Your First MQTT Connection
This tutorial walks you through establishing your first MQTT connection with mcmqtt, from basic pub/sub messaging to spawning your own brokers. Perfect for beginners and those new to MQTT.
## Prerequisites
- mcmqtt installed or accessible via `uvx`
- Basic understanding of command-line interfaces
- (Optional) MQTT client tools like `mosquitto_pub/sub` for testing
## Step 1: Start mcmqtt
First, let's get mcmqtt running:
```bash
# Start mcmqtt in STDIO mode (default)
uvx mcmqtt
# Or in HTTP mode for web integration
uvx mcmqtt --transport http --port 8080
```
You should see output like:
```
🚀 mcmqtt v2025.09.17 - FastMCP MQTT Server
✅ Server started in STDIO mode
📡 MQTT tools ready for MCP clients
🔧 Use 'mqtt_connect' to establish broker connections
```
## Step 2: Connect to an MQTT Broker
### Option A: Use an Existing Broker
If you have an MQTT broker running (like Mosquitto):
```python
# In Claude Code or your MCP client, use the mqtt_connect tool:
mqtt_connect({
"host": "localhost",
"port": 1883,
"client_id": "my-first-client",
"keepalive": 60
})
```
### Option B: Spawn a Broker with mcmqtt
mcmqtt can spawn a broker for you instantly:
```python
# Spawn a broker on port 1884
spawn_mqtt_broker({
"port": 1884,
"config": {
"allow_anonymous": true,
"max_connections": 100,
"log_level": "info"
}
})
```
Then connect to your new broker:
```python
mqtt_connect({
"host": "localhost",
"port": 1884,
"client_id": "my-spawned-broker-client"
})
```
## Step 3: Subscribe to Topics
Now let's listen for messages on a topic:
```python
# Subscribe to a simple topic
mqtt_subscribe({
"topic": "hello/world",
"qos": 1
})
# Subscribe to multiple topics with wildcards
mqtt_subscribe({
"topic": "sensors/+/temperature", # + matches one level
"qos": 0
})
mqtt_subscribe({
"topic": "events/#", # # matches multiple levels
"qos": 2
})
```
### Understanding QoS Levels
- **QoS 0**: At most once delivery (fire and forget)
- **QoS 1**: At least once delivery (guaranteed delivery)
- **QoS 2**: Exactly once delivery (guaranteed, no duplicates)
## Step 4: Publish Your First Message
Send a message to other subscribers:
```python
# Simple text message
mqtt_publish({
"topic": "hello/world",
"payload": "Hello from mcmqtt!",
"qos": 1,
"retain": false
})
# JSON payload with sensor data
mqtt_publish({
"topic": "sensors/living-room/temperature",
"payload": {
"value": 23.5,
"unit": "celsius",
"timestamp": "2024-01-15T10:30:00Z",
"sensor_id": "temp_001"
},
"qos": 1,
"retain": true # Retain for new subscribers
})
```
## Step 5: Test Your Connection
Let's verify everything is working by testing with external tools:
```bash
# In a new terminal, test with mosquitto clients
# Subscribe to your topic
mosquitto_sub -h localhost -p 1884 -t "hello/world"
# Publish a test message
mosquitto_pub -h localhost -p 1884 -t "hello/world" -m "Test from command line"
```
You should see the message appear in both your mcmqtt logs and the mosquitto subscriber.
## Step 6: Handle Connection Events
mcmqtt provides detailed connection status information:
```python
# Check connection status
mqtt_get_status()
# Response will show:
{
"connected": true,
"broker": "localhost:1884",
"client_id": "my-spawned-broker-client",
"subscriptions": [
{"topic": "hello/world", "qos": 1},
{"topic": "sensors/+/temperature", "qos": 0}
],
"messages_sent": 5,
"messages_received": 12,
"uptime": "00:05:23"
}
```
## Common Patterns
### Request-Response Pattern
Implement request-response over MQTT:
```python
# Client publishes request
mqtt_publish({
"topic": "requests/user-data",
"payload": {
"request_id": "req_001",
"user_id": "user123",
"reply_to": "responses/user-data/req_001"
}
})
# Subscribe to response
mqtt_subscribe({
"topic": "responses/user-data/req_001",
"qos": 1
})
```
### Heartbeat Monitoring
Keep track of client health:
```python
# Publish periodic heartbeat
mqtt_publish({
"topic": "heartbeat/my-client",
"payload": {
"timestamp": "2024-01-15T10:30:00Z",
"status": "healthy",
"memory_usage": "45%",
"cpu_usage": "12%"
},
"qos": 0,
"retain": true
})
```
### Event Streaming
Stream real-time events:
```python
# Stream application events
mqtt_publish({
"topic": "events/user-actions",
"payload": {
"event_type": "user_login",
"user_id": "user456",
"timestamp": "2024-01-15T10:30:00Z",
"metadata": {
"ip_address": "192.168.1.100",
"user_agent": "Mozilla/5.0..."
}
},
"qos": 1
})
```
## Troubleshooting
### Connection Refused
If you can't connect:
```bash
# Check if broker is running
netstat -an | grep :1883
# Check firewall settings
sudo ufw status
# Test basic connectivity
telnet localhost 1883
```
### Messages Not Received
If subscriptions aren't working:
```python
# Verify subscription was successful
mqtt_get_status()
# Check topic patterns match
# "sensors/+/temp" matches "sensors/room1/temp"
# but NOT "sensors/room1/humidity/temp"
# Verify QoS levels match publishing side
```
### Performance Issues
For high-throughput scenarios:
```python
# Increase connection limits
mqtt_connect({
"host": "localhost",
"port": 1883,
"client_id": "high-throughput-client",
"keepalive": 30,
"max_inflight_messages": 100,
"socket_options": {
"tcp_nodelay": true,
"buffer_size": 65536
}
})
```

"""Agent-to-agent coordination module for mcmqtt.
This module implements the host/join handshake protocol that ensures
agents don't experience "ships passing in the night" - dropped messages
because one agent published before the other subscribed.
The pattern is simple:
1. Initiating agent ALWAYS hosts (spawns broker, waits for joiners)
2. Joining agents connect and signal readiness
3. Only after all expected agents join does message exchange begin
Example:
# Agent A (initiator/host):
result = await mqtt_host_conversation(
session_id="collab-123",
expected_agents=["agent-b", "agent-c"],
timeout_seconds=30
)
# Returns broker connection info and confirms all agents joined
# Agent B (joiner):
result = await mqtt_join_conversation(
session_id="collab-123",
agent_id="agent-b",
broker_host="localhost",
broker_port=1883
)
# Returns when successfully joined and host acknowledged
