FilingSpy MCP

FilingSpy's Model Context Protocol server exposes 24 tools over MCP Streamable HTTP (JSON-RPC 2.0) for querying tracked superinvestor portfolios (13F), insider trades (Form 4), as-filed XBRL financial statements, filing text search and consensus/screener data from SEC EDGAR. Authenticated endpoint at /api/mcp requires a Bearer `fsk_` key; an anonymous demo endpoint at /api/mcp/demo exposes the same tools under a per-connection daily budget.
