About Yousign MCP Server
Connect your Yousign account to any AI agent and manage your electronic signature infrastructure through natural conversation.
Google ADK natively supports Yousign as an MCP tool provider — declare the Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 8 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.
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
The Yousign MCP Server exposes 8 tools through the Vinkius. Connect it to Google ADK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Google ADK with the Yousign MCP Server
Google ADK provides unique advantages when paired with Yousign through the Model Context Protocol.
Google ADK natively supports MCP tool servers — declare a tool provider and the framework handles discovery, validation, and execution
Built on Gemini models, ADK provides long-context reasoning ideal for complex multi-tool workflows with Yousign
Production-ready features like session management, evaluation, and deployment come built-in — not bolted on
Seamless integration with Google Cloud services means you can combine Yousign tools with BigQuery, Vertex AI, and Cloud Functions
Yousign + Google ADK Use Cases
Practical scenarios where Google ADK combined with the Yousign MCP Server delivers measurable value.
Enterprise data agents: ADK agents query Yousign and cross-reference results with internal databases for comprehensive analysis
Multi-modal workflows: combine Yousign tool responses with Gemini's vision and language capabilities in a single agent
Automated compliance checks: schedule ADK agents to query Yousign regularly and flag policy violations or configuration drift
Internal tool platforms: build self-service agent platforms where teams connect their own MCP servers including Yousign
