MCP Servers

secfinapi-mcp

MCP server for SEC Financial API providing access to financial data from the U.S. Securities and Exchange Commission.

README

secfinapi-mcp

MCP server for SECfinAPI — standardized SEC EDGAR financial data (income statements, balance sheets, cash flow, 50+ ratios) as tools for Claude, Cursor, and other AI assistants.

Ask your AI assistant things like "What's Apple's revenue trend?" or "Compare MSFT and GOOGL operating margins" — it fetches the data live through SECfinAPI.

It runs locally on your machine and is a thin wrapper over the SECfinAPI REST API. No server to host, no extra cost.

Setup

Get an API key (free) at https://www.secfinapi.com.
Add the server to your AI assistant's MCP config.
