How to Use the Yousign MCP in Google ADK

Q: How do I get signature evidence using Yousign and the Google ADK?

Run getaudittraillink. This function retrieves a direct link to the evidence file, which is crucial for linking signing proof directly back into your BigQuery datasets.

Q: Can I list all my signing requests using Yousign and the Google ADK?

Yes. Use listsignaturerequests to pull a full manifest of every request. This helps you monitor document lifecycle management across your entire enterprise platform.

Q: How do I manage signers using Yousign and the Google ADK?

You define required parties by calling addsignertorequest. The agent makes sure that every signer is properly associated with the document context before activation.

Q: What if I need to start a new signing process with Yousign and the Google ADK?

Start by invoking createsignaturerequest. This action initializes the entire workflow, allowing you to proceed with adding documents and defining signers from your Vertex AI agent.

Initiating Signatures with the MCP Server

The core action here is calling `create_signature_request` to start a new signing process. You'll then use `add_signer_to_request` to define exactly who needs to sign, making sure every necessary party is included in the flow. If you need to expand the scope of the document, you can run `add_document_to_request`, appending metadata or new PDFs directly into your BigQuery-backed agent workflow.

Tracking and Listing Requests

Need a status update? The agent calls `get_signature_request` to pull the current state of any given document. You can also check historical data with `list_signature_requests`, keeping track of every contract signed. For compliance, always retrieve the evidence via `get_audit_trail_link`. This link provides the definitive proof that ties back into your enterprise records.

Managing Contacts and Workspaces

You can maintain an address book using `list_yousign_contacts` or add new contacts with `create_yousign_contact`. This keeps the signing process self-contained within Google Cloud. You'll also use `get_workspace_details` to validate your account setup. If a request needs stopping, the agent uses `cancel_ongoing_request`, ensuring that unfinished processes don't clutter up your data sources.

Setup guide

Set up Yousign MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Yousign tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Yousign_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Yousign tools via MCP.",
    tools=mcp_tools,
)
