A deliberately thin bridge: the assistant asks for a quote, a history or what an instrument is, and the answer comes from the Twelve Data API rather than the model's memory. Coverage and rate limits are whatever your plan already gives you.
Twelve Data's open-source connector between its market-data API and MCP clients, so an assistant can fetch real-time and historical prices, time series and instrument reference data in a consistent format.
- Quotes, time series and instrument information for stocks, forex pairs and cryptocurrencies
- Real-time and historical data from the same Twelve Data API a trading dashboard would call
- A backend any MCP-compatible client or desktop app can point at
- A local or remote deployment, configured with your own API key
A Twelve Data API key, from registering at twelvedata.com. Run it with uv — uvx mcp-server-twelve-data --apikey YOUR_TWELVE_DATA_API_KEY — or install from pip and run mcp-server-twelve-data with the same flag, then point your client at the twelvedata server.
Build from source — clone the repository and build it, then deploy it and point your client at the endpoint
