Installation

pip install -e .
# or from PyPI (after publish): pip install kylas-crm-mcp-server

Configuration

Set environment variables (or use a .env file):

Variable	Required	Description
KYLAS_API_KEY	Yes	Your Kylas API key
KYLAS_BASE_URL	No	API base URL (default: https://api.kylas.io/v1)

Running the server

The server uses stdio transport (default for MCP). Run:

python -m kylas_crm_mcp
# or: python main.py  (when developing from repo root)

MCP clients (e.g. Cursor) typically start this process and communicate via stdin/stdout.

Docker

docker build -t kylas-crm-mcp .
docker run -e KYLAS_API_KEY=your_key -i kylas-crm-mcp

Development

pip install -e ".[dev]"
pytest

Publishing to the MCP Marketplace

To publish this server to the official MCP Registry (so it appears in Cursor and other MCP clients):

1. Publish the package to PyPI (the registry verifies ownership via your README).
2. Install mcp-publisher and run mcp-publisher login github, then mcp-publisher publish.
