 # mctelnet
 
-MCP server providing telnet client capabilities for LLMs. Connect to BBSes, MUDs, network devices, and any telnet-accessible system.
-
-## Installation
-
-```bash
-uvx mctelnet
-```
-
-Or add to Claude Code:
+**Telnet for LLMs.** Connect to BBSes, MUDs, network devices, or host your own telnet services.
 
 ```bash
 claude mcp add mctelnet "uvx mctelnet"
 ```
 
+## Why?
+
+LLMs can now interact with the vast world of telnet-accessible systems:
+- **Retro computing** - BBSes, ASCII art servers, text adventures
+- **Network ops** - Routers, switches, legacy infrastructure
+- **Automation** - Expect-style scripting for any interactive prompt
+- **Hosting** - Run telnet services that LLMs can manage
+
+## Quick Start
+
+```python
+# Watch Star Wars in ASCII (really!)
+connect("towel.blinkenlights.nl", 23, strip_ansi=True)
+
+# Login to a server
+expect_send(conn_id, "login:", "admin")
+expect_send(conn_id, "Password:", "secret", hide_send=True)
+expect_send(conn_id, "$ ", "uptime")
+```
+
 ## Features
 
-- **Multi-connection management** - Handle multiple simultaneous telnet sessions
-- **Expect-style automation** - Pattern matching for interactive prompts
-- **Script execution** - Run complete login/automation sequences
-- **Password hiding** - Redact sensitive data from outputs
+### Client Mode - Connect Anywhere
 
-## Tools
-
-| Tool | Description |
+| Tool | What it does |
 |------|-------------|
-| `connect` | Establish telnet connection, returns connection ID |
-| `send` | Send text to connection (auto-reads response) |
-| `read` | Read available data from connection |
-| `expect` | Wait for one of multiple patterns |
-| `expect_send` | Wait for pattern, then send text |
-| `run_script` | Execute expect-style automation script |
-| `list_connections` | Show all active connections |
-| `disconnect` | Close a connection |
-| `disconnect_all` | Close all connections |
+| `connect` | Connect with optional ANSI stripping, keepalive |
+| `send` | Send text, auto-read response |
+| `send_key` | Send escape sequences (ctrl-c, arrows, F-keys) |
+| `expect` | Wait for patterns (supports regex) |
+| `expect_send` | Wait then send - perfect for prompts |
+| `run_script` | Full automation sequences |
+| `connection_info` | Stats: bytes sent/received, uptime |
+| `get_transcript` | Complete session history |
 
-## Usage Examples
+### Server Mode - Host Services
 
-### Basic Interaction
+| Tool | What it does |
+|------|-------------|
+| `start_server` | Listen on a port (localhost by default) |
+| `list_clients` | See who's connected |
+| `send_client` | Send to specific client |
+| `broadcast` | Send to all clients |
+| `read_client` | Get buffered client input |
+
+## Examples
+
+### Expect-Style Automation
 
 ```python
-# Connect to a server
-conn = await connect("bbs.example.com", 23)
-# conn returns {"id": "abc123", ...}
-
-# Send a command
-await send("abc123", "help")
-
-# Disconnect
-await disconnect("abc123")
-```
-
-### Expect-Style Login
-
-```python
-# Connect and wait for login prompt
-conn = await connect("server.example.com", 23)
-
-# Handle login sequence
-await expect_send(conn_id, "login:", "myuser")
-await expect_send(conn_id, "Password:", "mypass", hide_send=True)
-await expect_send(conn_id, "$ ", "ls -la")
-```
-
-### Scripted Automation
-
-```python
-await run_script(conn_id, [
+# Scripted login + commands
+run_script(conn_id, [
     {"expect": "login:", "send": "admin"},
     {"expect": "Password:", "send": "secret", "hide": True},
     {"expect": "$ ", "send": "show version"},
-    {"expect": "$ ", "send": "show interfaces"},
     {"expect": "$ ", "send": "exit"}
 ])
 ```
 
-## Use Cases
+### Terminal Keys
 
-- Connecting to retro BBSes and MUDs
-- Network device configuration (routers, switches)
-- Legacy system automation
-- Interactive service testing
-- Terminal-based game playing
+```python
+# Send escape sequences
+send_key(conn_id, "ctrl-c")    # Interrupt
+send_key(conn_id, "up")        # Arrow key
+send_key(conn_id, "f1")        # Function key
+send_key(conn_id, "break")     # Telnet break
+
+# See all available keys
+list_keys()
+```
+
+### Regex Pattern Matching
+
+```python
+# Flexible matching
+expect(conn_id, [r"user(name)?:", r"login:"], regex=True)
+expect_send(conn_id, "password", "secret", ignore_case=True)
+```
+
+### Host a Service
+
+```python
+# Start server (binds localhost:2323)
+start_server(2323)
+
+# Send welcome to new connections
+send_client(server_id, client_id, "Welcome to my LLM-powered service!")
+
+# Broadcast to everyone
+broadcast(server_id, "Server shutting down in 5 minutes")
+```
+
+## Installation
+
+**With Claude Code:**
+```bash
+claude mcp add mctelnet "uvx mctelnet"
+```
+
+**Standalone:**
+```bash
+uvx mctelnet
+```
+
+**From source:**
+```bash
+git clone https://git.supported.systems/MCP/mctelnet
+cd mctelnet
+uv run mctelnet
+```
+
+## Security
+
+- Server mode binds to `127.0.0.1` by default (localhost only)
+- Port validation (1-65535)
+- Connection limits prevent resource exhaustion
+- Graceful shutdown cleans up all connections
