Automate document processing with CrewAI

Assign a specialized agent to manage your `list_sign_flows` data. It can monitor for pending signatures and report back to your primary team. This removes the manual burden of tracking contract progress. Your crew handles the monitoring while you focus on the outcome.

Execute sign flows through specialized agents

Give your agents access to `create_sign_flow` and `start_flow`. They can initiate agreements the moment a deal reaches a specific stage in your pipeline. This keeps your operations moving at machine speed. You define the roles, and the agents execute the paperwork.

Maintain audit trails via tool feedback

Use the output of `get_sign_flow` to keep a running log of every action taken on a contract. Your agents can store this data in shared memory. This ensures you always have a record of what happened and when. It’s the easiest way to keep your legal department informed.

Setup guide

Set up eSign (e签宝) 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 eSign (e签宝) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent eSign (e签宝) 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="eSign (e签宝) Analyst",
        goal="Access and analyze eSign (e签宝) data via MCP.",
        backstory="Expert analyst with direct eSign (e签宝) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent eSign (e签宝) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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