Create Signatures via MCP Server

Start a new signature workflow by calling `create_request`, which sets up the initial draft request and gives you an ID. You can then expand that job using `add_signer` to include specific signers' contact information. Later, if you need to confirm what documents were attached, run `list_documents` against the request ID.

Manage Request Status with Google ADK

The `get_request` tool provides comprehensive status and details for a single signature job. It's your main point of reference when tracking progress. If you need to audit all existing jobs, the `list_requests` function pulls every record in the Yousign organization.

Control Signature Lifecycle via MCP Server

The `activate_request` tool sends out the necessary email notifications that kick off the signing process for all participants. This is how you move from draft to active. Conversely, if a request needs to be stopped, `cancel_request` lets you permanently shut down the job using its ID.

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,
)
