Secfinapi MCP Server

What is Secfinapi?

Secfinapi is an MCP (Model Context Protocol) server that acts as a thin wrapper over the SECfinAPI REST API. It provides AI assistants such as Claude Desktop, Cursor, and VS Code with live, standardized financial data from SEC EDGAR — including income statements, balance sheets, cash flow statements, and over 40 financial ratios. The server runs locally on your machine, requires no separate hosting, and is intended for users who want to query U.S. public company financials directly from their AI assistant.

How to use Secfinapi?

1. Obtain a free API key at https://www.secfinapi.com.
2. Add the server to your AI assistant’s MCP configuration. For Claude Desktop, open Settings → Developer → Edit Config and insert the appropriate JSON block (either the npm published version or a local build) with the SECFINAPI_KEY environment variable set to your key. For Cursor/VS Code, use the same configuration shape.
3. Restart the assistant. Six tools (e.g., get_income_statement, get_balance_sheet, get_metrics, list_companies) become available under the tools menu.
