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 add new A record for your domain, list all firewall rules for zone, show members of your Cloudflare account, 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.

Connecting Cloudflare to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

3. Connect your Cloudflare account

Back in Claude, ask it to connect to Cloudflare or give it any Cloudflare-related task.

For example, ask Claude to:

  • "Add new A record for your domain"
  • "List all firewall rules for zone"
  • "Show members of your Cloudflare account"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Cloudflare account is ready to use.

What is the Cloudflare Claude Connector, 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 to your Cloudflare infrastructure, so your agent can perform actions like managing DNS records, configuring WAF lists, auditing firewall rules, and overseeing zones and account members—all on your behalf.

  • DNS record management: Effortlessly create or delete DNS records within any zone, allowing your agent to automate domain setup and maintenance tasks.
  • WAF list and firewall rule automation: Direct your agent to create, list, or delete Web Application Firewall (WAF) lists and audit firewall rules to enhance your site's security posture.
  • Zone administration: Enable your agent to create new zones when adding domains or delete zones that are no longer needed, streamlining domain onboarding and cleanup.
  • Account and member management: Let your agent list all Cloudflare accounts you have access to and enumerate members within each account for audit or collaboration purposes.
  • Comprehensive infrastructure visibility: Ask your agent to fetch and review your entire Cloudflare account structure, making it simple to monitor resources and configurations at scale.

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.

FAQ

Frequently asked questions

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.

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.

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.

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.
