FAQ from Remote MCP Server on Cloudflare

How do I develop the server locally?

Clone the repository, run npm install, then execute npx nx dev remote-mcp-server. Open http://localhost:8787/ in your browser.

How can I test my server with the MCP Inspector?

Start the MCP Inspector with npx @modelcontextprotocol/inspector, switch Transport Type to SSE, and enter http://localhost:8787/sse (or your remote URL) as the server URL. Log in with any email and password on the mock login screen.

How do I deploy the server to Cloudflare?
