## Architecture
### MCP Server Components
This project implements a Model Context Protocol (MCP) server for KiCad electronic design automation. The architecture follows MCP patterns with three main component types:
**Resources** (read-only data):
- `kicad://projects` - List KiCad projects
- `kicad://project/{project_path}` - Project details
- `kicad://drc_report/{project_path}` - DRC reports
- `kicad://bom/{project_path}` - Bill of materials
- `kicad://netlist/{project_path}` - Circuit netlists
- `kicad://patterns/{project_path}` - Circuit pattern analysis
**Tools** (actions/computations):
- Project management (open projects, analysis)
- DRC checking with KiCad CLI integration
- BOM generation and export
- PCB visualization and thumbnails
- Circuit pattern recognition
- File export operations
**Prompts** (reusable templates):
- PCB debugging assistance
- BOM analysis workflows
- Circuit pattern identification
- DRC troubleshooting
### Key Modules
#### Core Server (`kicad_mcp/server.py`)
- FastMCP server initialization with lifespan management
- Registers all resources, tools, and prompts
- Signal handling for graceful shutdown
- Cleanup handlers for temporary directories
#### Configuration (`kicad_mcp/config.py`)
- Platform-specific KiCad paths (macOS/Windows/Linux)
- Environment variable handling (`KICAD_SEARCH_PATHS`, `KICAD_USER_DIR`)
- Component library mappings and default footprints
- Timeout and display constants
#### Context Management (`kicad_mcp/context.py`)
- Lifespan context with KiCad module availability detection
- Shared cache across requests
- Application state management
#### Security Features
- Path validation utilities in `utils/path_validator.py`
- Secure subprocess execution in `utils/secure_subprocess.py`
- Input sanitization for KiCad CLI operations
- Boundary validation for file operations
### KiCad Integration Strategy
- **Primary**: KiCad CLI (`kicad-cli`) for all operations
- **Fallback**: Direct file parsing for basic operations
- **Detection**: Automatic KiCad installation detection across platforms
- **Isolation**: Subprocess-based execution for security
mckicad is a FastMCP 3 server for KiCad electronic design automation. It uses src-layout packaging with `hatchling` as the build backend.

## Development Notes
### Key Design Decisions
### Adding New Features
1. Identify component type (resource/tool/prompt)
2. Add implementation to appropriate module in `kicad_mcp/`
3. Register in `server.py` create_server() function
4. Use lifespan context for shared state and caching
5. Include progress reporting for long operations
**Lazy config** (`config.py`): All environment-dependent values are accessed via functions (`get_search_paths()`, `get_kicad_user_dir()`) called at runtime, not at import time. Static constants (`KICAD_EXTENSIONS`, `TIMEOUT_CONSTANTS`, `COMMON_LIBRARIES`) remain as module-level dicts since they don't read env vars. This eliminates the .env load-order race condition.
### KiCad CLI Integration
- All KiCad operations use CLI interface for security
- CLI detection in `utils/kicad_cli.py`
- Path validation prevents directory traversal
- Subprocess timeouts prevent hanging operations
**Decorator-based tool registration**: Each tool module imports `mcp` from `server.py` and decorates functions with `@mcp.tool()` at module level. `server.py` imports the modules to trigger registration. No `register_*_tools()` boilerplate.
### Testing
- Unit tests in `tests/unit/`
- Test markers: `unit`, `integration`, `requires_kicad`, `slow`, `performance`
- Coverage target: 80% (configured in pyproject.toml)
- Run with: `pytest` or `make test`
**Schematic abstraction point**: `tools/schematic.py` uses `kicad-sch-api` for file-level schematic manipulation. The `_get_schematic_engine()` helper exists as a swap point for when kipy adds schematic IPC support.
### Configuration
- Environment variables override defaults in `config.py`
- `.env` file support for development
- Platform detection for KiCad paths
- Search path expansion with `~` support
**Dual-mode operation**: PCB tools work via IPC (kipy, requires running KiCad) or CLI (kicad-cli, batch mode). Tools degrade gracefully when KiCad isn't running.
### Entry Point
- `main.py` is the server entry point
- Handles logging setup and .env file loading
- Manages server lifecycle with proper cleanup
- Uses asyncio for MCP server execution
### Tool Registration Pattern
```python
# tools/example.py
from mckicad.server import mcp
@mcp.tool()
def my_tool(param: str) -> dict:
"""Tool description for the calling LLM."""
return {"success": True, "data": "..."}
```
### Tool Return Convention
All tools return dicts with at least `success: bool`. On failure, include `error: str`. On success, include relevant data fields.
## Adding New Features
1. Choose the right module (or create one in `tools/`)
2. Import `mcp` from `mckicad.server`
3. Decorate with `@mcp.tool()` and add a clear docstring
4. If new module: add import in `server.py`
5. Write tests in `tests/test_<module>.py`
## Security
- All file paths validated via `utils/path_validator.py` before access
- External commands run through `utils/secure_subprocess.py` with timeouts
- KiCad CLI commands sanitized — no shell injection
- `main.py` inline .env loader runs before any mckicad imports
## Environment Variables
- `KICAD_USER_DIR` - KiCad user config directory
- `KICAD_SEARCH_PATHS` - Comma-separated project search paths
- `KICAD_CLI_PATH` - Explicit kicad-cli path
- `FREEROUTING_JAR_PATH` - Path to FreeRouting JAR
- `LOG_LEVEL` - Logging level (default: INFO)
## Testing
Markers: `unit`, `integration`, `requires_kicad`, `slow`, `performance`
```bash
make test # all tests
make test tests/test_schematic.py # one file
uv run pytest -m "unit" # by marker
```
## Entry Point
```toml
[project.scripts]
mckicad = "mckicad.server:main"
```
Run via `uvx mckicad`, `uv run mckicad`, or `uv run python main.py`.
## FreeRouting Setup
1. Download JAR from https://freerouting.app/
2. Place at `~/freerouting.jar`, `/usr/local/bin/freerouting.jar`, or `/opt/freerouting/freerouting.jar`
3. Install Java runtime
4. Verify with `check_routing_capability()` tool
5. Or set `FREEROUTING_JAR_PATH` in `.env`
## Logging
Logs go to `mckicad.log` in project root, overwritten each start. Never use `print()` — MCP uses stdin/stdout for JSON-RPC transport.

## 🚀 Quick Start: Experience the Magic
### 1. **Installation** (2 minutes)
```bash
# Clone the repository
git clone https://github.com/lamaalrajih/kicad-mcp.git
cd kicad-mcp
# Install dependencies – `uv` will create a `.venv/` folder automatically
# (Install `uv` first: `brew install uv` on macOS or `pipx install uv`)
# Clone and setup
git clone https://github.com/your-org/mckicad.git
cd mckicad
make install
# Optional: activate the environment for manual commands
source .venv/bin/activate
```
### 2. Configure Your Environment
Create a `.env` file to customize where the server looks for your KiCad projects:
```bash
# Copy the example environment file
# Configure environment
cp .env.example .env
# Edit the .env file
vim .env
# Edit .env with your KiCad project paths
```
In the `.env` file, add your custom project directories:
```
# Add paths to your KiCad projects (comma-separated)
KICAD_SEARCH_PATHS=~/pcb,~/Electronics,~/Projects/KiCad
```
### 3. Run the Server
Once the environment is set up, you can run the server:
```bash
python main.py
```
### 4. Configure an MCP Client
Now, let's configure Claude Desktop to use our MCP server:
1. Create or edit the Claude Desktop configuration file:
```bash
# Create the directory if it doesn't exist
mkdir -p ~/Library/Application\ Support/Claude
# Edit the configuration file
vim ~/Library/Application\ Support/Claude/claude_desktop_config.json
```
2. Add the KiCad MCP server to the configuration:
### 2. **Configure Claude Desktop** (1 minute)
```json
{
"mcpServers": {
"kicad": {
"command": "/ABSOLUTE/PATH/TO/YOUR/PROJECT/kicad-mcp/.venv/bin/python",
"args": [
"/ABSOLUTE/PATH/TO/YOUR/PROJECT/kicad-mcp/main.py"
]
}
"mcpServers": {
"kicad": {
"command": "/path/to/mckicad/.venv/bin/python",
"args": ["/path/to/mckicad/main.py"]
}
}
}
```
Replace `/ABSOLUTE/PATH/TO/YOUR/PROJECT/kicad-mcp` with the actual path to your project directory.
### 5. Restart Your MCP Client
Close and reopen your MCP client to load the new configuration.
## Understanding MCP Components
The Model Context Protocol (MCP) defines three primary ways to provide capabilities:
### Resources vs Tools vs Prompts
**Resources** are read-only data sources that LLMs can reference:
- Similar to GET endpoints in REST APIs
- Provide data without performing significant computation
- Used when the LLM needs to read information
- Typically accessed programmatically by the client application
- Example: `kicad://projects` returns a list of all KiCad projects
**Tools** are functions that perform actions or computations:
- Similar to POST/PUT endpoints in REST APIs
- Can have side effects (like opening applications or generating files)
- Used when the LLM needs to perform actions in the world
- Typically invoked directly by the LLM (with user approval)
- Example: `open_project()` launches KiCad with a specific project
**Prompts** are reusable templates for common interactions:
- Pre-defined conversation starters or instructions
- Help users articulate common questions or tasks
- Invoked by user choice (typically from a menu)
- Example: The `debug_pcb_issues` prompt helps users troubleshoot PCB problems
For more information on resources vs tools vs prompts, read the [MCP docs](https://modelcontextprotocol.io/docs/concepts/architecture).
## Feature Highlights
The KiCad MCP Server provides several key features, each with detailed documentation:
- **Project Management**: List, examine, and open KiCad projects
- *Example:* "Show me all my recent KiCad projects" → Lists all projects sorted by modification date
- **PCB Design Analysis**: Get insights about your PCB designs and schematics
- *Example:* "Analyze the component density of my temperature sensor board" → Provides component spacing analysis
- **Netlist Extraction**: Extract and analyze component connections from schematics
- *Example:* "What components are connected to the MCU in my Arduino shield?" → Shows all connections to the microcontroller
- **BOM Management**: Analyze and export Bills of Materials
- *Example:* "Generate a BOM for my smart watch project" → Creates a detailed bill of materials
- **Design Rule Checking**: Run DRC checks using the KiCad CLI and track your progress over time
- *Example:* "Run DRC on my power supply board and compare to last week" → Shows progress in fixing violations
- **PCB Visualization**: Generate visual representations of your PCB layouts
- *Example:* "Show me a thumbnail of my audio amplifier PCB" → Displays a visual render of the board
- **Circuit Pattern Recognition**: Automatically identify common circuit patterns in your schematics
- *Example:* "What power supply topologies am I using in my IoT device?" → Identifies buck, boost, or linear regulators
For more examples and details on each feature, see the dedicated guides in the documentation. You can also ask the LLM what tools it has access to!
## Natural Language Interaction
While our documentation often shows examples like:
### 3. **Start Creating Magic** ✨
```
Show me the DRC report for /Users/username/Documents/KiCad/my_project/my_project.kicad_pro
💬 "Create a complete outlet tester project with voltage display and GFCI testing"
💬 "Automatically route my existing Arduino shield PCB"
💬 "Analyze the thermal performance of my power supply board"
💬 "Generate manufacturing files for my LED controller"
```
You don't need to type the full path to your files! The LLM can understand more natural language requests.

### Adding New Features
---
To add new features to the KiCad MCP Server, follow these steps:
## 🎨 Customization & Extension
1. Identify the category for your feature (resource, tool, or prompt)
2. Add your implementation to the appropriate module
3. Register your feature in the corresponding register function
4. Test your changes with the development tools
### **Adding Your Own Circuit Patterns**
See [Development Guide](docs/development.md) for more details.
Want the AI to recognize your custom circuit patterns? Easy:
## Troubleshooting
```python
# Add custom pattern recognition
@register_pattern("custom_power_supply")
def detect_my_power_supply(components, nets):
# Your pattern detection logic
return pattern_info
If you encounter issues:
# AI will now recognize and suggest optimizations
# for your custom power supply topology
```
1. **Server Not Appearing in MCP Client:**
- Check your client's configuration file for errors
- Make sure the path to your project and Python interpreter is correct
- Ensure Python can access the `mcp` package
- Check if your KiCad installation is detected
### **Custom Automation Workflows**
2. **Server Errors:**
- Check the terminal output when running the server in development mode
- Check Claude logs at:
- `~/Library/Logs/Claude/mcp-server-kicad.log` (server-specific logs)
- `~/Library/Logs/Claude/mcp.log` (general MCP logs)
```python
# Create project-specific automation
@mcp.tool()
def automate_iot_sensor_design(requirements: dict):
"""Complete IoT sensor automation with your specific needs"""
# Custom logic for your domain
return automated_project
```
3. **Working Directory Issues:**
- The working directory for servers launched via client configs may be undefined
- Always use absolute paths in your configuration and .env files
- For testing servers via command line, the working directory will be where you run the command
