## Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.
This guide walks you through the easiest and most secure way to connect your Cloudflare account to Claude via Composio Connect, enabling it to list active firewall rules for domain, purge cache for specific URL, create DNS record for example.com, and more such actions on your behalf without compromising your account security.
Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

## What is the Cloudflare MCP server, and what's possible with it?

The Cloudflare MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cloudflare account. It provides structured and secure access so your agent can perform Cloudflare operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CLOUDFLARE_MCP_DOCS` | Docs | Search the Cloudflare documentation. This tool should be used to answer any question about Cloudflare products or features, including: - Workers, Pages, R2, Images, Stream, D1, Durable Objects, KV, Workflows, Hyperdrive, Queues - AI Search, Workers AI, Vectorize, AI Gateway, Browser Rendering - Zero Trust, Access, Tunnel, Gateway, Browser Isolation, WARP, DDOS, Magic Transit, Magic WAN - CDN, Cache, DNS, Zaraz, Argo, Rulesets, Terraform, Account and Billing Results are returned as semantically similar chunks to the query. |
| `CLOUDFLARE_MCP_EXECUTE` | Execute | Execute JavaScript code against the Cloudflare API. First use the 'search' tool to find the right endpoints, then write code using the cloudflare.request() function. Available in your code: interface CloudflareRequestOptions { method: "GET" \| "POST" \| "PUT" \| "PATCH" \| "DELETE"; path: string; query?: Record; body?: unknown; contentType?: string; // Custom Content-Type header (defaults to application/json if body is present) rawBody?: boolean; // If true, sends body as-is without JSON.stringify } interface CloudflareResponse { success: boolean; status: number; result: T; errors: Array; messages: Array; result_info?: { page: number; per_page: number; total_pages: number; count: number; total_count: number; }; } declare const cloudflare: { request(options: CloudflareRequestOptions): Promise>; }; declare const accountId: string; // accountId is pre-set to "e8a40544a7211334b83bf588bbf7dec1" (Qa@agent51testing.com's Account) — use it directly in API paths. Your code must be an async arrow function that returns the result. Example: Worker with bindings (requires multipart/form-data): async () => { const code = `addEventListener('fetch', e => e.respondWith(MY_KV.get('key').then(v => new Response(v \|\| 'none'))));`; const metadata = { body_part: "script", bindings: [{ type: "kv_namespace", name: "MY_KV", namespace_id: "your-kv-id" }] }; const b = `--F${Date.now()}`; const body = [`--${b}`, 'Content-Disposition: form-data; name="metadata"', 'Content-Type: application/json', '', JSON.stringify(metadata), `--${b}`, 'Content-Disposition: form-data; name="script"', 'Content-Type: application/javascript', '', code, `--${b}--`].join("\\r\\n"); return cloudflare.request({ method: "PUT", path: `/accounts/${accountId}/workers/scripts/my-worker`, body, contentType: `multipart/form-data; boundary=${b}`, rawBody: true }); } |
| `CLOUDFLARE_MCP_SEARCH` | Search | Search the Cloudflare OpenAPI spec. All $refs are pre-resolved inline. Products: cloudforce-one, access, magic, workers, dlp, realtime, email-security, devices, email, ai-gateway, intel, gateway, stream, brand-protection, settings, ai-search, data-security, browser-rendering, dex, logpush, api_gateway, builds, addressing, images, load_balancers, security-center, rulesets, vectorize, firewall, logs... (160 total) Types: interface OperationInfo { summary?: string; description?: string; tags?: string[]; parameters?: Array; requestBody?: { required?: boolean; content?: Record }; responses?: Record }>; } interface PathItem { get?: OperationInfo; post?: OperationInfo; put?: OperationInfo; patch?: OperationInfo; delete?: OperationInfo; } declare const spec: { paths: Record; }; Examples: // Find endpoints by product 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; } // Get endpoint with requestBody schema (refs are resolved) async () => { const op = spec.paths['/accounts/{account_id}/d1/database']?.post; return { summary: op?.summary, requestBody: op?.requestBody }; } // Get endpoint parameters async () => { const op = spec.paths['/accounts/{account_id}/workers/scripts']?.get; return op?.parameters; } |

## Troubleshooting

### 1. Why does Claude not use the Composio connector for Cloudflare?

The connector can show as connected, but Claude must use it in each Cloudflare conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to Cloudflare again.

### 2. Why does Claude show an MCP server error before Cloudflare connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Cloudflare.
- Check that the connector URL is https://connect.composio.dev/mcp.
- Connectors run from Anthropic's cloud, so your device network is usually not the problem.
- Add the connector again from Customize > Connectors, then ask Claude to connect Cloudflare.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the Cloudflare authorization link not work?

The Composio connector is one server. Your Cloudflare account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the Cloudflare connection.
- Composio creates a fresh Cloudflare authorization link.
- Open that link in your browser and finish the Cloudflare sign-in.

### 4. Why do Cloudflare actions fail after they worked before?

The Cloudflare connection can expire or lose permission.
- Ask Claude to inspect the Cloudflare connection.
- If the connection is unhealthy, disconnect it when Claude prompts you.
- Reconnect the Cloudflare account and retry the action.
- If Claude shows a permission prompt, approve it before Claude changes data in Cloudflare.
- If the action still fails with a permission error, check that the connected account has that permission in Cloudflare itself.

### 5. How do I switch to a different Cloudflare account?

Claude can manage the Cloudflare connection for you.
- Ask Claude to disconnect or delete the current Cloudflare account.
- Ask Claude to connect Cloudflare again.
- Open the new Composio authorization link for Cloudflare.
- Sign in with the other Cloudflare account in the browser.
- After the account connects, ask Claude to retry the Cloudflare task.

### 6. Why is my Cloudflare connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Cloudflare connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If Cloudflare tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
- On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Cloudflare.

## Creating MCP Server - Stand-alone vs Composio SDK

The Cloudflare MCP server connects Claude Web, Desktop, and Cowork to your Cloudflare account through Composio. Once connected, Claude can use the available Cloudflare tools and triggers to complete tasks on your behalf.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Cloudflare MCP?

With a standalone Cloudflare MCP server, the agents and LLMs can only access a fixed set of Cloudflare tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Cloudflare and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Cloudflare tools.

### Can I manage the permissions and scopes for Cloudflare while using Tool Router?

Yes, absolutely. You can configure which Cloudflare scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Cloudflare data and credentials are handled as safely as possible.
