About Yousign MCP Server
Connect your Yousign account to any AI agent and manage your electronic signature infrastructure through natural conversation.
LlamaIndex agents combine Yousign tool responses with indexed documents for comprehensive, grounded answers. Connect 8 tools through the Vinkius and query live data alongside vector stores and SQL databases in a single turn — ideal for hybrid search, data enrichment, and analytical workflows.
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 LlamaIndex 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 LlamaIndex with the Yousign MCP Server
LlamaIndex provides unique advantages when paired with Yousign through the Model Context Protocol.
Data-first architecture: LlamaIndex agents combine Yousign tool responses with indexed documents for comprehensive, grounded answers
Query pipeline framework lets you chain Yousign tool calls with transformations, filters, and re-rankers in a typed pipeline
Multi-source reasoning: agents can query Yousign, a vector store, and a SQL database in a single turn and synthesize results
Observability integrations show exactly what Yousign tools were called, what data was returned, and how it influenced the final answer
Yousign + LlamaIndex Use Cases
Practical scenarios where LlamaIndex combined with the Yousign MCP Server delivers measurable value.
Hybrid search: combine Yousign real-time data with embedded document indexes for answers that are both current and comprehensive
Data enrichment: query Yousign to augment indexed data with live information before generating user-facing responses
