Equibles MCP Server

Connect Equibles to Claude, Cursor or any other MCP client and it stops being a tab you switch to. US stock-market & financial data: SEC filings, fundamentals, holdings, insider trades, calls, FRED. The equibles mcp server is what makes that connection.

What the server does

90+ MCP tools for AI agents like Claude, ChatGPT and Cursor: SEC filings, fundamentals, 13F institutional holdings, insider and congressional trades, earnings call transcripts, short interest and macro data. Free hosted tier, or self-host the open-source stack.

The Model Context Protocol (MCP) lets AI assistants call external data tools instead of guessing from training data. Equibles exposes US stock market and financial data as an MCP server: use it hosted at https://mcp.equibles.com/mcp (free API key, or OAuth with no key at all), or run it yourself from the open-source stack. Everything is parsed from the primary sources (SEC EDGAR, FINRA, FRED, CFTC, CBOE, USAspending, company IR sites), not from third-party estimates.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• ChatGPT — Add a developer-mode connector with URL https://mcp.equibles.com/mcp and complete the OAuth sign-in (or use the ?api_key=eq_your_api_key URL)
• Cursor — The Cursor tool exposed by this server

Credentials and setup notes

Configuration is passed through the environment: MCP_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Equibles's toolset — ChatGPT, Cursor — is a fair guide to whether it matches your workflow. It is maintained by daniel3303; worth a glance at recent repository activity before you build anything load-bearing on it.

Worth knowing first

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
