Clous MCP server

A Model Context Protocol server for the Clous API — entity-resolved SEC/EDGAR filings data for AI agents. Point Claude Desktop, Cursor, or any MCP client at Clous and search filings, pull financials, insider trades, 13F holdings, Form D raises, and more through one consistent JSON envelope.

This is a thin, open-source client. It forwards tool calls to https://api.clous.ai using your API key (via the CLOUS_API_KEY environment variable). No key or secret is bundled here. All data derives from public SEC EDGAR filings; Clous is independent of the SEC.

      "command": "npx",
      "args": ["-y", "@clous/mcp"],

git clone https://github.com/clousai/mcp.git clous-mcp
cd clous-mcp
npm install
npm run build
CLOUS_API_KEY=clous_live_... node dist/index.js   # speaks MCP over stdio
