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

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

The ManyReach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your ManyReach account. It provides structured and secure access to your outreach campaigns, prospects, mailing lists, senders, messages, tags, and workspace details, so your agent can create campaigns, organize prospects, review outreach messages, check senders, and manage tags on your behalf.

  • Campaign planning and management: Have your agent create draft campaigns, find existing campaigns by status, and update their configuration.
  • Prospect and mailing list organization: Let the agent create, find, and update prospects, then create, rename, or reorganize mailing lists for targeted outreach.
  • Message and reply review: Instruct your agent to retrieve sent messages and replies using campaign, sender, address, subject, follow-up, or CRM status filters.
  • Sender and tag management: Direct your agent to find sender mailboxes by connection or warmup state, and create, find, or update tags for prospects, campaigns, and senders.
  • Account monitoring and cleanup: Have your agent check organization details, sending credits, and data token balances, or permanently remove campaigns, prospects, mailing lists, and tags you no longer need.

FAQ

Frequently asked questions

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

Yes, absolutely. You can configure which ManyReach 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.
