Key point

An MCP server has been released that lets LLMs directly query financial data such as insider trading and SEC filings.

Details

OpenInsider MCP is a Model Context Protocol (MCP) server that enables LLM clients (Claude Desktop, Cursor, VS Code, etc.) to directly query financial research data.

Without consuming context through web browsing, this server provides 16 investment research signals through 4 major data sources:

  • OpenInsider: Form 4 insider trading information
  • SEC EDGAR: 8-K material events, 13D activist filings, S-3/424B5 dilution information, etc.
  • FINRA / SEC: short interest, daily short sale volume, fails-to-deliver (FTD), etc.
  • Yahoo Finance: real-time stock prices, valuation, dividends, earnings announcement schedules

The server focuses on serving as a data layer, providing raw, unprocessed data without its own scoring or editorializing. Users and LLMs can directly reason about investment strategies based on the provided data.

Installation is supported via npm, and it can be immediately integrated into various MCP-compatible clients using the npx command.
