Self-hosted Twelve Data MCP alternatives
Twelve Data's MCP server installs locally and runs over stdio, so the process and your API key stay on your own machine. If you want that same local setup with a different financial data domain, the servers below run the same way.
One honest note: the market data itself still comes from each provider's API, so self-hosting controls where the server process and credentials live, not where the data is sourced. The picks below cover different slices of financial data, each running locally.

FAQ
- Is the Twelve Data MCP server self-hosted?
- Yes. It installs locally and runs over stdio, so the process and your API key stay on your machine. The alternatives here, including SEC EDGAR, yfinance, Financial Modeling Prep, FRED, Alpaca, Alpha Vantage, and CoinGecko, also run locally.
- Does self-hosting keep the market data on my own machine?
