Agent-Driven Contract Lifecycle

A research agent can use `get_contract_details` to gather all necessary metadata on a document. Then, an action agent uses that data to call `create_shangqian_contract`, generating the draft. This autonomous process ensures every stage of contract setup is logged and monitored by the crew.

Specialized Identity Handling

An identity agent can independently run `verify_identity_v2` to confirm user status. The results are then shared memory for other agents, who use that confirmation to proceed with signing. This role-based specialization prevents unnecessary API calls and keeps the operation tight.

Template Management Workflow

A dedicated agent can manage templates by calling `upload_shangqian_template`. Another agent can then use the template ID with `create_shangqian_contract` to generate a full document. The system ensures that every contract adheres to the most recently uploaded, approved template.

Setup guide

Set up ShangQian / 上上签 (BestSign) MCP in CrewAI

Prerequisites

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

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke ShangQian / 上上签 (BestSign) tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="ShangQian / 上上签 (BestSign) Analyst",
    goal="Access and analyze ShangQian / 上上签 (BestSign) data via MCP.",
    backstory="Expert analyst with direct ShangQian / 上上签 (BestSign) access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent ShangQian / 上上签 (BestSign) transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="ShangQian / 上上签 (BestSign) Analyst",
        goal="Access and analyze ShangQian / 上上签 (BestSign) data via MCP.",
        backstory="Expert analyst with direct ShangQian / 上上签 (BestSign) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent ShangQian / 上上签 (BestSign) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)

Common questions about ShangQian / 上上签 (BestSign) MCP in CrewAI

You pass the MCP Server URL directly to your agents. The crew then treats all exposed tools—like `sign_contract_now` or `get_user_certificate`—as specialized skills that can be called when needed.

The server handles user certificates, contract metadata, and template content. The agents work together to maintain consistency across these three critical data points.

Yes. You can assign a specialized 'Signature Agent' that only has access to the `sign_contract_now` tool, ensuring it performs its function without interference from other operational agents.

The agent framework allows you to create specialized workflows. One crew might focus on drafting using `upload_shangqian_template`, while another focuses solely on signing.

The server touches user certificates, which contain sensitive identity information. Always ensure your crew's memory and tool logging adhere to strict regional compliance protocols.
