Equibles — Stock Market & Financial Data MCP Server

111 MCP tools for AI agents like Claude, ChatGPT and Cursor: SEC filings, fundamentals, 13F institutional holdings, insider and congressional trades, earnings call transcripts, options chains, live quotes, IPO filings, short interest, macro data, and your own portfolio. Free hosted tier, or self-host the open-source stack.

What is this?

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.

Quickstart (hosted, 30 seconds)

1. Create a free account at equibles.com — no credit card required.
2. Create an API key at https://equibles.com/dashboard/apikeys. It starts with eq_ and is shown once, so copy it right away.
3. Connect your client with the URL https://mcp.equibles.com/mcp (see below).

ChatGPT and Claude (web and Desktop) can skip the key entirely and sign in over OAuth.

Connect your AI client

Claude Desktop / Claude web (claude.ai)

Settings → Connectors → Add custom connector → URL https://mcp.equibles.com/mcp → sign in over OAuth (no key needed).

Key alternative: use the URL https://mcp.equibles.com/mcp?api_key=eq_your_api_key.

Claude Code

claude mcp add --transport http equibles https://mcp.equibles.com/mcp

Then run /mcp and choose Authenticate to sign in over OAuth.

Key alternative:

claude mcp add-json equibles '{"type":"http","url":"https://mcp.equibles.com/mcp","headers":{"Authorization":"Bearer eq_your_api_key"}}' --scope user

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

Add to ~/.cursor/mcp.json:

{ "mcpServers": { "equibles": { "url": "https://mcp.equibles.com/mcp", "headers": { "Authorization": "Bearer eq_your_api_key" } } } }

VS Code (Copilot)

code --add-mcp '{"name":"equibles","type":"http","url":"https://mcp.equibles.com/mcp"}'

Or add a .vscode/mcp.json with a "servers" object using the same URL and Authorization header shape:

{ "servers": { "equibles": { "type": "http", "url": "https://mcp.equibles.com/mcp", "headers": { "Authorization": "Bearer eq_your_api_key" } } } }

Any MCP client

Use the HTTP transport with URL https://mcp.equibles.com/mcp, authenticating with an Authorization: Bearer eq_... header or a ?api_key=eq_... query parameter.

After connecting, see the full per-client guides at https://equibles.com/docs/mcp.
