Deploy to Cloudflare

npm install
npm run check
npm run deploy

After deploying, your MCP URL is:

https://<your-worker-subdomain>/mcp

Use that address when adding a remote MCP connector.

Examples

  • get_stock_quote: symbol = AAPL, market = us

  • get_sec_company_filings: ticker = NVDA, limit = 10

  • get_world_bank_indicator: country = KOR, indicator = NY.GDP.MKTP.CD

  • search_clinical_trials: query = pancreatic cancer

Development notes

  • The Worker uses the MCP TypeScript SDK's stateless Streamable HTTP transport.

  • All requests are read-only. No brokerage, account, or trading actions are included.

  • The SEC asks automated clients to identify themselves. This server identifies itself with this repository URL.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
