What It Does¶

The Stock Market MCP Server is one of the most comprehensive free financial MCP servers on the market — 90+ tools exposing SEC filings, institutional holdings, insider and congressional trades, earnings call transcripts, short interest data, FRED macroeconomic indicators, and more. Built on the Equibles financial data platform.

AI agents can:

SEC Filings: Retrieve company filings, financial statements, and disclosures directly from EDGAR
13F Holdings: Query institutional investor portfolios — see what hedge funds and asset managers hold
Insider & Congressional Trades: Track insider buying/selling and congressional stock trading activity
Earnings Calls: Pull transcripts of quarterly earnings calls for any public company
Short Interest: Monitor short interest data and borrow rates
FRED Macro: Access Federal Reserve Economic Data — GDP, employment, inflation, interest rates
Stock Quotes: Real-time and historical price data across global exchanges

Think of it as "Bloomberg Terminal light" — 90+ financial intelligence tools accessible through natural language conversation.

Why This Matters for Operators¶

Financial operators' single pane: Instead of juggling SEC.gov, FRED, insider-trade trackers, and earnings transcripts across multiple websites, operators ask one question and get sourced answers.
Free tier, no friction: No credit card required for the free tier. Operators can start querying financial data in one terminal command.
90+ tools = deep coverage: Most financial MCPs offer 5-20 tools. Stock Market MCP's 90+ tools cover every major financial data surface operators need — from macro (FRED) to micro (individual filings).
Complements the catalog: Existing financial MCPs specialize (Alpha Vantage for stocks, Ko Financial for SEC/insider, FinData for quotes). Stock Market MCP bundles them all — making it the go-to for operators who want one financial MCP instead of three.

Setup¶

Caveats¶

New project: Only 2 GitHub stars — the server is days old. Expect rapid iteration and possible breaking changes.
Free tier limits: The free tier has rate limits; check equibles.com for current pricing.
Financial data latency: Real-time quotes may have 15-minute delays depending on exchange. SEC/FRED data is official and up-to-date.
Local only: This is a stdio MCP server — it runs on your machine, not as a hosted remote endpoint.
