Cloudflare MCP Server

A token-efficient MCP server for the entire Cloudflare API. 2500 endpoints in 1k tokens, powered by Code Mode.

Token Comparison

Get Started

MCP URL: https://mcp.cloudflare.com/mcp

Option 1: OAuth (Recommended)

Just connect to the MCP server URL - you'll be redirected to Cloudflare to authorize and select permissions.

Example JSON Configuration

{
  "mcpServers": {
    "cloudflare-api": {
      "type": "http",
      "url": "https://mcp.cloudflare.com/mcp"
    }
  }
}

Option 2: API Token

For CI/CD, automation, or if you prefer managing tokens yourself.

Create a Cloudflare API token with the permissions you need. Both user tokens and account tokens are supported. For account tokens, include the Account Resources : Read permission so the server can auto-detect your account ID.

Note: API tokens with Client IP Address Filtering enabled are not currently supported.

Disable Code Mode

If your MCP client already uses code mode, or you're composing this server with another server that uses code mode, you can disable it with the ?codemode=false query parameter. This registers an individual tool for each of the ~2,500 Cloudflare API endpoints instead of the code mode API tools. The docs tool remains available in both modes.

https://mcp.cloudflare.com/mcp?codemode=false

Example JSON Configuration

{
  "mcpServers": {
    "cloudflare-api": {
      "type": "http",
      "url": "https://mcp.cloudflare.com/mcp?codemode=false"
    }
  }
}

When code mode is disabled:

• Each API endpoint is registered as its own tool (e.g., get_workers_scripts, post_d1_database)
• Tool input schemas are derived from the endpoint's path parameters, query parameters, and request body
• Tools make direct API calls — no code execution involved
• Path parameters like account_id are auto-resolved when possible (single account)

Note: Disabling code mode significantly increases the token cost (~244k tokens vs ~1k tokens). Only disable it when necessary for composition with other code mode systems.

The Problem

The Cloudflare OpenAPI spec is 2 million tokens. Even with native MCP tools using minimal schemas, it's still ~244k tokens. Traditional MCP servers that expose every endpoint as a tool leak this entire context to the main agent.

This server solves the problem by using code execution in a Code Mode pattern - the spec lives on the server, and only the result of the code execution is returned to the agent.

Tools

Agent writes code to search the spec and execute API calls. It can also search Cloudflare's developer documentation directly.

Supported Products

Workers, KV, R2, D1, Pages, DNS, Firewall, Load Balancers, Stream, Images, AI Gateway, Vectorize, Access, Gateway, and more. See the full Cloudflare API schemas.

Usage

Once configured, just ask your agent to do things with Cloudflare:

• "List all my Workers"
• "Create a KV namespace called 'my-cache'"
• "Add an A record for api.example.com pointing to 192.0.2.1"

The agent will search for the right endpoints and execute the API calls. Here's what happens behind the scenes:

…

GraphQL Analytics API

The server automatically detects and handles Cloudflare's GraphQL Analytics API endpoints. GraphQL queries work seamlessly through the same execute tool:

…

Build a Code Mode MCP Server

Code execution uses Cloudflare's Dynamic Worker Loader API to run generated code in isolated Workers, following the Code Mode pattern.
