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

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

The Signaturely MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Signaturely account. It provides structured and secure access to your Signaturely workspace, so your agent can perform actions like listing documents, retrieving templates, managing agreements, and streamlining your signature workflows on your behalf.

  • Comprehensive document retrieval: Quickly list and view all documents in your Signaturely account, making it easy to track agreements, contracts, and signed files.
  • Template management: Let your agent fetch and organize reusable document templates, streamlining the process of preparing new signature requests.
  • Automated document discovery: Effortlessly filter and search for specific documents based on status, type, or other criteria, so you always find what you need.
  • Workflow optimization: Use AI to surface relevant templates or documents for various business scenarios, helping you automate signature processes and reduce manual work.

FAQ

What are the differences in Tool Router MCP and Signaturely MCP?

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

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

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