## 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 api key through MCP without you sharing account credentials directly with the agent.

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

The Cloudflare api key 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 services, so your agent can create DNS records, manage security rules, delete zones, and automate zone configurations on your behalf.
- Automated DNS record management: Instantly create, update, or delete DNS records—including A, CNAME, TXT, and MX types—across your Cloudflare zones to keep your domains running smoothly.
- Zone lockdown and security automation: Add or remove Zone Lockdown rules to restrict access to specific URLs and IP ranges, helping you enforce security policies without manual intervention.
- Ruleset creation and maintenance: Direct your agent to create new rulesets or modify existing ones, ensuring your web applications remain secure and compliant with evolving access requirements.
- Comprehensive zone administration: Effortlessly delete entire zones or DNSSEC configurations for streamlined domain management and cleanup when needed.
- Versioned ruleset management: Retrieve specific versions of entry point rulesets, giving you granular control and auditability over your security configurations.
