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

The eSignatures MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your eSignatures account. It provides structured and secure access to your contract templates, contracts, signers, and signing workflows, so your agent can create and send contracts, manage signers, update content, track signing status, and organize templates on your behalf.

• Contract creation and delivery: Have your agent create contract drafts from templates or Markdown, send them for signature, or send an existing draft when it is ready.
• Signer management: Let the agent add, update, or remove signers from editable contracts, resend signature requests, and adjust signer contact, delivery, authentication, or redirect details.
• Template creation and collaboration: Direct your agent to create, duplicate, rename, label, or delete reusable templates, and manage the collaborators who can edit them.
• Contract and template editing: Instruct your agent to preview and apply exact content changes, update contract placeholder values, and review template or contract Markdown.
• Signing workflow tracking: Have your agent check contract details, current status, signers, completed field values, and signed documents when available, or withdraw an active unsigned contract.
