Configuration

• Requires a valid DESK3_API_KEY (set in your environment or .env file).

Quickstart

Prerequisites

• Python 3.12 or higher
• uv package manager

Install and Run

uv sync
uv run desk3_service

Docker

docker build -t desk3-service .
docker run -e DESK3_API_KEY=your_api_key_here -p 8100:8100 desk3-service

Startup Modes

This project supports two startup modes:

1. HTTP/SSE Server (Recommended)

Launches a Starlette HTTP/SSE server on 0.0.0.0:8100 for use with Dify, Claude, Notion MCP, etc.

# Recommended: run directly with Python
PYTHONPATH=src python -m desk3_service.http_server
# Or run the Starlette MCP server variant
PYTHONPATH=src python -m desk3_service.starlette_mcp_server

Or, if you want to use uv/pyproject.toml script, add a script entry for http_server or starlette_mcp_server.

2. MCP Stdio Server (Advanced)

Launches a pure MCP stdio server for CLI or advanced integration (not HTTP/SSE):

uv run desk3_service

This mode is only needed if you want to use MCP over stdin/stdout (not recommended for most users).

Troubleshooting

• Make sure uv is installed and in your PATH.
• Ensure your DESK3_API_KEY is valid.
• If using Docker, set the API key with -e DESK3_API_KEY=....
