Manage the entire signing lifecycle via MCP Server.

The `create_shangqian_contract` tool lets your agent generate a new, structured signature agreement. You provide basic details, and the server handles the contract creation process. The system also uses `get_user_certificate` to verify credentials before signing. This whole sequence ensures that when you call `sign_contract_now`, the contract is valid and ready for immediate execution.

Verify Identity with OpenAI Agents SDK

Need to confirm a person's identity? Use `verify_identity_v2`. This tool runs the full verification flow, making sure the user signing has the proper credentials. It’s your first checkpoint before any sensitive action. After successful verification, your agent can then call `register_shangqian_user` to set up a new account within the ShangQian / 上上签 (BestSign) platform.

Secure Contract Retrieval and Templates

The `get_contract_details` tool pulls all the metadata for an existing contract, giving you key IDs and statuses without needing the file itself. It’s a quick way to check status. If your workflow needs new types of agreements, use `upload_shangqian_template`. This lets your agent upload custom documents so they can be used later when calling `create_shangqian_contract`.

Setup guide

Set up ShangQian / 上上签 (BestSign) MCP in OpenAI Agents SDK

Prerequisites

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

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all ShangQian / 上上签 (BestSign) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives ShangQian / 上上签 (BestSign) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate ShangQian / 上上签 (BestSign) tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="ShangQian / 上上签 (BestSign) Agent",
            instructions="You have access to ShangQian / 上上签 (BestSign) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
