FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to my local MCP server?

Edit your Claude configuration file to add an mcpServers entry using npx mcp-remote http://localhost:8787/sse. Restart Claude and you should see the available tools.

How do I deploy the MCP server to Cloudflare?

Run npx wrangler kv namespace create OAUTH_KV, add the returned KV namespace ID to wrangler.jsonc, then execute npm run deploy.

What should I do if something goes wrong?

Restart Claude, or try connecting directly to your MCP server with npx mcp-remote http://localhost:8787/sse. In rare cases, clear the auth files with rm -rf ~/.mcp-auth.

How can I test my MCP server remotely?

Use the MCP Inspector: run npx @modelcontextprotocol/inspector, set Transport Type to SSE, and enter your deployed workers.dev/sse URL (e.g., worker-name.account-name.workers.dev/sse).

What transport does the server use?

The server communicates via SSE (Server-Sent Events) over HTTP, as shown in the development and production connection URLs ending in /sse.
