Secfinapi

MCP server for SECfinAPI — standardized SEC EDGAR financial data (income statements, balance sheets, cash flow, 40+ 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

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

Claude Desktop

Open Settings → Developer → Edit Config and add:

Once published to npm:

{
  "mcpServers": {
    "secfinapi": {
      "command": "npx",
      "args": ["-y", "secfinapi-mcp"],
      "env": { "SECFINAPI_KEY": "your-api-key-here" }
    }
  }
}

Running from source (before publishing):

  "mcpServers": {
    "secfinapi": {
      "command": "node",
      "args": ["C:/path/to/sec-financial-mcp/dist/index.js"],
