the13f-mcp
Model Context Protocol server for the13f. Brings institutional 13F intelligence into Claude Desktop, Cursor, VS Code + Continue, and any MCP-compatible host — no HTTP code required on your side.
Important limitations
Research data only. Sourced from publicly disclosed SEC Form 13F filings,
which lag quarter-end by up to 45 days. Past institutional positioning does
not predict future performance. Nothing here constitutes investment advice.
Every tool's response includes a disclaimer field; the host LLM should
surface it alongside any analysis it produces.
Install
uvx the13f-mcpOr pip install the13f-mcp if you prefer to manage Python environments
yourself. Python 3.11+ required.
