4. Connect your Cloudflare account

Back in Cowork, ask the agent to connect to Cloudflare or give it any Cloudflare-related task.

For example, ask Cowork 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 Cowork, and your Cloudflare account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Cloudflare through MCP without you sharing account credentials directly with the agent.

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 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.

FAQ

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.
