Which integrations are available for this server?

Provides comprehensive access to the complete Cloudflare API, allowing agents to search for specific endpoints within the OpenAPI spec and execute requests to manage Cloudflare services and configurations. Enables the management and querying of Cloudflare Workers, including searching for worker-related endpoints and executing scripts to retrieve or update worker resources via the Cloudflare API.

How do I use Cloudflare MCP?

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., "@Cloudflare MCP list all the cloudflare workers in my account" 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.

cloudflare-mcp

A smol MCP server for the complete Cloudflare API.

Deploy to Cloudflare Workers

Uses codemode to avoid dumping too much context to your agent.

Get Started

Create API Token

Create a Cloudflare API token with the permissions you need.

Both user tokens and account tokens are supported:

Token Type	Description	Requirements
User Token	Created at user level, can access multiple accounts	Requires `account_id` parameter on each execute call
Account Token	Scoped to single account	`account_id` auto-detected, no parameter needed

For account tokens, include the Account Resources : Read permission so the server can auto-detect your account ID.

Add to Agent

MCP URL: https://cloudflare-mcp.mattzcarey.workers.dev/mcp Bearer Token: Your Cloudflare API Token

Claude Code

export CLOUDFLARE_API_TOKEN="your-token-here" claude mcp add --transport http cloudflare-api https://cloudflare-mcp.mattzcarey.workers.dev/mcp \ --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

OpenCode

Set your API token as an environment variable:

export CLOUDFLARE_API_TOKEN="your-token-here"

Then add to your opencode.json:

{ "mcp": { "cloudflare-api": { "type": "remote", "url": "https://cloudflare-mcp.mattzcarey.workers.dev/mcp", "headers": { "Authorization": "Bearer {env:CLOUDFLARE_API_TOKEN}" } } } }

The Problem

The Cloudflare OpenAPI spec is 2.3 million tokens in JSON format. Even compressed to TypeScript endpoint summaries, it's still ~50k tokens. Traditional MCP servers that expose every endpoint as a tool, or include the full spec in tool descriptions, leak this entire context to the main agent.

This server solves the problem by using code execution in a codemode pattern - the spec lives on the server, and only the results of queries are returned to the agent.

Tools

Two tools where the agent writes code to search the spec and execute API calls. Akin to ACI.dev's MCP server but with added codemode.

Tool	Description
`search`	Write JavaScript to query `spec.paths` and find endpoints
`execute`	Write JavaScript to call `cloudflare.request()` with the discovered endpoints

Token usage: Only search results and API responses are returned. The 6MB spec stays on the server.

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; }`, });

Token Comparison

Content	Tokens
Full OpenAPI spec (JSON)	~2,352,000
Endpoint summary (TypeScript)	~43,000
Typical search result	~500
API response	varies

Architecture

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