Enables deployment of a remote MCP server without authentication to Cloudflare Workers.
Offers integration with the mcp-remote proxy package to connect local MCP clients to the remote server.
Building a Remote MCP Server on Cloudflare (Without Auth)
This example allows you to deploy a remote MCP server that doesn't require authentication on Cloudflare Workers.
Get started:
This will deploy your MCP server to a URL like: remote-mcp-server-authless.<your-account>.workers.dev/sse
Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:
Customizing your MCP Server
To add your own tools to the MCP server, define each tool inside the init()
method of src/index.ts
using this.server.tool(...)
.
Tavily News Search Tool
This MCP server includes a news search tool powered by the Tavily API. To use it:
- Sign up for a Tavily API key at tavily.com
- Add your API key to the
wrangler.jsonc
file in the"vars"
section: - For production, it's recommended to use Cloudflare Workers Secrets instead:
News Search Response Format
The searchNews
tool returns news results in a structured text format:
To parse these results into JSON in your client application, you can extract the information from the formatted text response.
Connect to Cloudflare AI Playground
You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:
- Go to https://playground.ai.cloudflare.com/
- Enter your deployed MCP server URL (
remote-mcp-server-authless.<your-account>.workers.dev/sse
) - You can now use your MCP tools directly from the playground!
Connect Claude Desktop to your MCP server
You can also connect to your remote MCP server from local MCP clients, by using the mcp-remote proxy.
To connect to your MCP server from Claude Desktop, follow Anthropic's Quickstart and within Claude Desktop go to Settings > Developer > Edit Config.
Update with this configuration:
Restart Claude and you should see the tools become available.
