About mcp_massive
massive-com/mcp_massive
An MCP server for Massive.com Financial Market Data
Exposes four composable tools—search, docs, call, and query—that let LLMs discover and invoke any Massive.com API endpoint, with support for in-memory DataFrame storage and SQL querying via SQLite. Includes built-in financial functions (Black-Scholes Greeks, moving averages, Sharpe/Sortino ratios) applicable to API results or stored data. Dynamically indexes the entire API surface from Massive.com's `llms.txt` at startup, ensuring automatic synchronization with new endpoints and data coverage across stocks, options, crypto, fundamentals, and market data.
