Deploy to Cloudflare Workers

Deploy your MCP server to Cloudflare Workers for global edge distribution and zero-ops scaling using Speakeasy’s built-in Cloudflare deployment configuration.

Prerequisites

Before deploying to Cloudflare Workers, you need to do the following:

Generate an MCP server using Speakeasy.
Install the Wrangler CLI .
Set up a Cloudflare account.

Configuration

Enable Cloudflare Worker deployment by adding the following configuration to your .speakeasy/gen.yaml file:


mcp-typescript:
  cloudflareEnabled: true
  cloudflareURL: https://your-worker-name.your-subdomain.workers.dev

Configuration options

cloudflareEnabled: Set to true to enable Cloudflare Worker deployment configuration.
cloudflareURL: This is the URL where your MCP server will be deployed. It should match the URL of your Cloudflare Worker.

The cloudflareURL determines the endpoint where your MCP server will be accessible after deployment. Make sure this matches your intended Worker domain.

Generating the deployment

After configuring your gen.yaml file, regenerate your SDK to include Cloudflare Worker deployment files:


speakeasy run

This creates an additional file in your generated SDK for the Cloudflare Worker.

Deployment process

Use the following steps to deploy your MCP server on a Cloudflare worker.

Authenticate with Cloudflare:
```
npx wrangler login
```
Navigate to your generated SDK directory and deploy your MCP server:
```
npx wrangler deploy
```
Verify that your MCP server is running at the URL specified in your cloudflareURL configuration by accessing it via curl:
```
curl https://your-worker-name.your-subdomain.workers.dev/
```
Alternatively, navigate to the URL in a browser window to view the MCP Server configuration.

Using the deployed server

Configure your MCP client to connect to the deployed Cloudflare Worker. Different clients use different configuration formats.

Claude Code

Use the Claude Code CLI to add your deployed MCP server with the following command:


claude mcp add --transport sse MyAPI https://your-worker-name.your-subdomain.workers.dev/sse \
--header "X-API-Key: your-api-key-here"

Windsurf

Add the server configuration to your Windsurf MCP settings:


{
  "mcpServers": {
    "MyAPI": {
      "serverUrl": "https://your-worker-name.your-subdomain.workers.dev/sse",
      "headers": {
        "X-API-Key": "your-api-key-here"
      }
    }
  }
}

Cursor

Configure your MCP server in Cursor’s settings:


{
  "mcpServers": {
    "MyAPI": {
      "url": "https://your-worker-name.your-subdomain.workers.dev/mcp",
      "headers": {
        "X-API-Key": "your-api-key-here"
      }
    }
  }
}

Note the different endpoint paths: Claude Code and Windsurf use /sse for server-sent events, while Cursor uses /mcp for the standard MCP protocol endpoint.

Updating your deployment

You can update your deployed MCP server as follows:

Make changes to your OpenAPI document.
Regenerate your SDK with the following command:
```
speakeasy run
```
Redeploy by running the following command:
```
npx wrangler deploy
```
