About Yousign MCP Server
Connect your Yousign account to any AI agent and manage your electronic signature infrastructure through natural conversation.
Mastra's agent abstraction provides a clean separation between LLM logic and Yousign tool infrastructure. Connect 8 tools through the Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution — deployable to any Node.js host in one command.
What you can do
- Signature Lifecycle — Create new signature requests in draft mode, add signers, and activate requests to send them for signing
- Request Monitoring — List and browse all signature processes and retrieve real-time status (draft, ongoing, done, cancelled)
- Signer Management — Define and add multiple signers to a request by providing their contact details directly from your agent
- Document Discovery — List all files attached to a specific signature request to verify the contents before activation
- Cancellation Control — Permanently stop ongoing signature requests and provide custom reasons for termination through simple commands
- Quota Auditing — Retrieve API consumption and credit details to monitor your Yousign plan usage and remaining signatures
- Deep Discovery — Quickly find unique request, signer, and document IDs required for automated legal workflows
