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

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

The Zoho 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 Zoho mail account. It provides structured and secure access to your mailbox, so your agent can perform actions like searching emails, sending messages, managing folders, organizing conversations, and handling attachments on your behalf.

  • Smart email search and filtering: Ask your agent to find emails based on sender, subject, keywords, or date ranges for quick information retrieval.
  • Automated composing and sending: Let your agent draft and send new emails, reply to existing threads, or create message templates to streamline communication.
  • Folder and label organization: Have your agent organize your inbox by moving messages to folders, applying tags, or archiving threads for a clutter-free workspace.
  • Attachment management: Retrieve, download, or send attachments through your agent—making file sharing and access seamless within your email workflow.
  • Bulk message actions: Instruct your agent to mark emails as read or unread, star important messages, or clean up your inbox by deleting or archiving in bulk.

FAQ

What are the differences in Tool Router MCP and Zoho mail MCP?

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

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

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