Remote Deployment

For cloud deployment on AWS Lambda, you can use the mcp-remote adapter to enable Claude Desktop connectivity:

{
  "mcpServers": {
    "wa-leg": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://your-api-gateway-url/sse"
      ]
    }
  }
}

Basic Configuration

Create a .env file:

WSL_API_TIMEOUT=30
WSL_CACHE_TTL=300
LOG_LEVEL=INFO
SERVER_NAME="Washington State Legislature MCP Server"

Development

Setting Up Development Environment

1. Clone the repository:

git clone https://github.com/awalcutt/wa-leg-mcp.git
cd wa-leg-mcp

2. Create virtual environment:

python -m venv venv
source venv/bin/activate  # Or `venv\Scripts\activate` on Windows

3. Install development dependencies:

pip install -e ".[dev]"

4. Run tests:

make test

Adding New Tools

1. Create a new file in src/wa_leg_mcp/tools/
2. Implement tool using the MCP decorator:

from mcp.server.fastmcp import Tool

@Tool("toolName", description="Tool description")
def tool_function(param1: str, param2: str = None):
    # Implementation
    return {"result": data}

3. Register tool in server.py by adding it to the get_default_tools() function
4. Add tests in tests/
