Allows deploying and running an MCP server on Cloudflare Workers infrastructure with OAuth login capabilities

How do I use Remote MCP Server on Cloudflare?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Remote MCP Server on Cloudflare connect to my Cloudflare MCP server with OAuth" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Remote MCP Server on Cloudflare

Let's get a remote MCP server up-and-running on Cloudflare Workers complete with OAuth login!

Develop locally

# clone the repository git clone git@github.com:cloudflare/ai.git # install dependencies cd ai npm install # run locally npx nx dev remote-mcp-server-bearer-auth

You should be able to open http://localhost:8787/ in your browser

Connect the MCP inspector to your server

To explore your new MCP api, you can use the MCP Inspector.

Start it with npx @modelcontextprotocol/inspector
Within the inspector, switch the Transport Type to SSE and enter http://localhost:8787/sse as the URL of the MCP server to connect to.
Add a bearer token and click "Connect"
Click "List Tools"
Run the "getToken" tool, which should return the Authorization header that you set in the inspector

Connect Claude Desktop to your local MCP server

{ "mcpServers": { "remote-mcp-server-bearer-auth": { "command": "npx", "args": [ "mcp-remote", "http://localhost:8787/sse", "--header", "Authorization: Bearer ${AUTH_TOKEN}" ] }, "env": { "AUTH_TOKEN": "..." } } }

Deploy to Cloudflare

npm run deploy

Call your newly deployed remote MCP server from a remote MCP client

Just like you did above in "Develop locally", run the MCP inspector:

npx @modelcontextprotocol/inspector@latest

Then enter the workers.dev URL (ex: worker-name.account-name.workers.dev/sse) of your Worker in the inspector as the URL of the MCP server to connect to, and click "Connect".

You've now connected to your MCP server from a remote MCP client. You can pass in a bearer token like mentioned above

Debugging

Should anything go wrong it can be helpful to restart Claude, or to try connecting directly to your MCP server on the command line with the following command.

npx mcp-remote http://localhost:8787/sse

In some rare cases it may help to clear the files added to ~/.mcp-auth

rm -rf ~/.mcp-auth
