}Search for API endpoints and built-in functions by natural language query. Returns titles, path patterns, and descriptions. Set `detail` to `"more"` for query parameter docs, or `"verbose"` for full documentation. Use `max_results` to limit results.
Call any Massive.com REST API endpoint. Supports storing results as an in-memory database table (`store_as`) and applying post-processing functions (`apply`). Paginated responses include a next-page hint.
Run SQL against stored SQLite DB. Supports `SHOW TABLES`, `DESCRIBE <table>`, `DROP TABLE <table>`, CTEs, window functions, and more. Results can also be post-processed with `apply`.
The Massive.com MCP Server gives LLMs access to the full Massive.com financial data API through three composable tools: search, call, and query. Data can be stored in an in-memory SQLite database and enriched with built-in financial functions. It is for developers who want to integrate market data into AI assistants.
Install with uv tool install "mcp_massive @ git+https://github.com/massive-com/mcp_massive@v0.10.0" and set the MASSIVE_API_KEY environment variable. Then register the server with Claude Code (claude mcp add massive...) or add it to your Claude Desktop configuration. The LLM uses three tools: search_endpoints to discover endpoints and functions, call_api to fetch data, and query_data to run SQL against stored results.
llms.txt stays current automatically.Stock, options, forex, crypto, and futures aggregates; real-time and historical trades and quotes; market snapshots, gainers/losers; ticker details; dividends, splits, IPOs; financial fundamentals; analyst ratings and news; treasury yields, inflation data; market status and holidays.
Python 3.12+, a Massive.com API key, and Astral UV v0.4.0+.
`MASSIVE_API_KEY` is required. Optional: `MCP_TRANSPORT` (default `stdio`), `MASSIVE_API_BASE_URL`, `MASSIVE_LLMS_TXT_URL`, `MASSIVE_MAX_TABLES` (default 50), `MASSIVE_MAX_ROWS` (default 50000).
The API key is used only for authenticating requests to Massive.com. No personal data is stored or cached; all requests are proxied directly.
STDIO by default. SSE and streamable-http are also supported via the `--transport` CLI argument or `MCP_TRANSPORT` environment variable.
