Deploying to Cloudflare Workers

This guide covers deploying a Model Context Protocol server on Cloudflare Workers using the streamable-http transport. This deployment model is advanced difficulty.

Prerequisites

  • Cloudflare account
  • Wrangler CLI
  • OAuth 2.0 credentials or an API key for the server

Deployment Steps

  1. Prepare your server build. Ensure your MCP server builds cleanly: npm run build
  2. Write the configuration.
    # Deploy to Cloudflare Workers
# See full guide for platform-specific commands
  3. Set environment variables. Never bake secrets into container images or deployment configs. Use the platform's secret management system.
  4. Deploy and verify. After deployment, test the Streamable HTTP endpoint responds with a valid MCP response.
  5. Configure your client. Add the deployed server URL to your client configuration.

Production Security Checklist

  • Serve over HTTPS only — never expose MCP servers on plain HTTP.
  • Enforce authentication on every endpoint — no unauthenticated access.
  • Set NODE_ENV=production to disable debug output.
  • Apply network egress rules to limit what the server can reach.
  • Enable request logging and ship logs to a central SIEM.
