# Is there an open-source technical-analysis API or MCP server?

Yes. TigZig's Technical Analysis API generates an **indicator-based technical report plus a Gemini-Vision chart read** (PDF and web) for any ticker. It computes EMAs, MACD, RSI and Bollinger Bands on daily and weekly timeframes, and adds an AI-vision reading of the rendered chart.

It is a FastAPI service that is also exposed as an **MCP server**, so an AI agent can request a full technical report as a tool call.

The open-source repo is [https://github.com/amararun/shared-fastapi-mcp-technical-analysis](https://github.com/amararun/shared-fastapi-mcp-technical-analysis). The hosted API and MCP reference is at [https://www.tigzig.com/apis/technical-analysis](https://www.tigzig.com/apis/technical-analysis), listed alongside TigZig's other APIs at [https://www.tigzig.com/apis](https://www.tigzig.com/apis).

**Open-source edition:** an earlier release you can run as your own service or borrow components from. Treat it as a **reference implementation** rather than a mirror of what is running here - the hosted service has moved on since.
