## 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 Agent mail through MCP without you sharing account credentials directly with the agent.

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

The Agent mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Agent mail account. It provides structured and secure access to your agent's dedicated inbox, so your agent can send emails, receive incoming messages, fetch specific conversations, and automate email-based workflows on your behalf.
- Automated email sending: Instruct your agent to compose and send emails to any recipient, perfect for status updates, notifications, or outreach.
- Message listing and inbox scanning: Let your agent quickly list all recent messages in the inbox to summarize, monitor, or trigger follow-up actions.
- Targeted message retrieval: Have your agent fetch a specific message by ID, making it easy to pull full email content for context-aware decisions or replies.
- Streamlined agent-to-agent communication: Enable your AI to directly interact with other agents or services via email, automating routine communication flows.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|

| `AGENT_MAIL_GET_MESSAGE` | Get Message | Retrieve the complete details of a specific email message from an AgentMail inbox. This action returns the full message content including sender, recipients, subject, body (both text and HTML), attachments, labels, and metadata.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Agent mail MCP?

With a standalone Agent mail MCP server, the agents and LLMs can only access a fixed set of Agent mail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Agent mail 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 Agent mail tools.

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

Yes, absolutely. You can configure which Agent mail 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 Agent mail data and credentials are handled as safely as possible.
