MCP.Pizza Chef: cloudflare

Cloudflare is the company many businesses use to host websites, store files, manage domain names, and block online attacks. This tool connects your AI assistant to your Cloudflare account so you can check on your sites, spin up new storage, update domain records, and review traffic numbers just by describing what you want in plain words. It works inside any AI assistant that lets you add this kind of outside connection. You'll need a Cloudflare account, and you can sign in through a quick authorization screen or create your own account token for automated setups.

README

Cloudflare MCP Server

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

Token Comparison

Approach Tools Token cost Context used (200K)
Raw OpenAPI spec in prompt ~2,000,000 977%
Native MCP (full schemas) 2,594 1,170,523 585%
Native MCP (minimal — required params only) 2,594 244,047 122%
Code mode 3 ~1,100 0.5%

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.

Add to Agent

Setting Value
MCP URL https://mcp.cloudflare.com/mcp
Bearer Token Your Cloudflare API Token

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.

Tool Description
docs Search Cloudflare developer documentation
search Write JavaScript to query spec.paths and find endpoints
execute Write JavaScript to call cloudflare.request() with the discovered endpoints

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:

// 1. Search for endpoints
search({
  code: `async () => {
    const results = [];
    for (const [path, methods] of Object.entries(spec.paths)) {
      for (const [method, op] of Object.entries(methods)) {
        if (op.tags?.some(t => t.toLowerCase() === 'workers')) {
          results.push({ method: method.toUpperCase(), path, summary: op.summary });
        }
      }
    }
    return results;
  }`,
});

// 2. Execute API call (user token - account_id required)
execute({
  code: `async () => {
    const response = await cloudflare.request({
      method: "GET",
      path: \`/accounts/\${accountId}/workers/scripts\`
    });
    return response.result;
  }`,
  account_id: "your-account-id",
});

// 2. Execute API call (account token - account_id auto-detected)
execute({
  code: `async () => {
    const response = await cloudflare.request({
      method: "GET",
      path: \`/accounts/\${accountId}/workers/scripts\`
    });
    return response.result;
  }`,
});

GraphQL Analytics API

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

execute({
  code: `async () => {
    const response = await cloudflare.request({
      method: "POST",
      path: "/client/v4/graphql",
      body: {
        query: \`query {
          viewer {
            zones(filter: { zoneTag: "your-zone-id" }) {
              httpRequests1dGroups(limit: 7, orderBy: [date_ASC]) {
                dimensions {
                  date
                }
                sum {
                  requests
                  bytes
                  cachedBytes
                }
              }
            }
          }
        }\`,
        variables: {}
      }
    });
    return response.result;
  }`,
  account_id: "your-account-id",
});

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.

mcp FAQ

Can I use this to update my website's settings without logging into Cloudflare's dashboard?
Yes — you can ask your AI assistant to change domain records, turn on security features, or check a site's status, and it applies those changes directly to your Cloudflare account.
Can I use this to see how much traffic my website is getting?
Yes — you can ask for recent visitor and traffic numbers for any site connected to your Cloudflare account, and the assistant pulls the numbers for you.
Do I need a Cloudflare account already set up?
Yes. This tool connects to an existing Cloudflare account — it manages the sites, storage, and settings you already have rather than creating a new account for you.
Do I need to create a special key or token to connect?
Not necessarily. The simplest way is to sign in through a quick authorization screen when you connect, though you can also create your own access token if you want more control over what it's allowed to do.
How hard is this to set up?
It's about as simple as it gets — you add one web address to your AI assistant's connection settings, then sign in and approve access when prompted.
Which AI apps can I use this with?
Any AI assistant that lets you add an outside connection or tool of this kind. Check your assistant's settings for an option like "add connection," "add tool," or "add integration."
Will this let my AI assistant make changes without asking me first?
That depends on your AI assistant's own settings — most let you review or approve actions before they happen, so check your assistant for a confirmation option.
Can I limit what this is allowed to do in my Cloudflare account?
Yes — if you connect using your own access token instead of the quick sign-in, you can limit it to only the permissions you choose, such as read-only access or access to a single site.
