How to Use the eSign (e签宝) MCP in AutoGen

Q: Can AutoGen agents verify eSign (e签宝) organization details before signing?

Yes. A dedicated auditor agent can call getorginfo to verify company registration details before the coordinator agent triggers startflow.

Let AutoGen agents debate contract terms, verify signer details, and execute eSign (e签宝) workflows via consensus.

Perplexity

Multi-agent legal review

AutoGen allows you to set up a conversational loop between specialized agents. A compliance agent can review contract details, while a coordinator agent calls `create_sign_flow` and `add_docs` once the terms are agreed upon. This keeps your legal team in control without slowing down the process. The agents debate the details, and only trigger `start_flow` once all automated validation checks pass.

Verify signers using AutoGen and MCP

Before sending a high-value contract, your agents can cross-verify signer identity. An assistant agent calls `get_org_info` to check organization data, while another agent runs validation checks before calling `add_signers` to finalize the flow. This multi-agent consensus reduces the risk of sending sensitive agreements to the wrong parties. The MCP Server ensures your agents have direct access to eSign (e签宝) identity records during their debate.

Automated exception handling

When a signing flow fails or is rejected, your agents can collaborate on the resolution. One agent calls `get_sign_flow` to retrieve the failure reason, while another agent drafts a corrected document and calls `add_docs` to restart the flow. This keeps your contract operations running without human intervention for simple errors. The agents handle the back-and-forth, only alerting a human if the API returns a critical error.

Setup guide

Set up eSign (e签宝) MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes eSign (e签宝) tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

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

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="eSign (e签宝)_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent eSign (e签宝) data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

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

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="eSign (e签宝)_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent eSign (e签宝) data")
    print(result.messages[-1].content)

Common questions about eSign (e签宝) MCP in AutoGen

The agents discuss the contract parameters first. Once they reach consensus, the execution agent calls `create_sign_flow` and `add_signers` via the MCP Server.

Yes. A dedicated auditor agent can call `get_org_info` to verify company registration details before the coordinator agent triggers `start_flow`.

After the agents agree to start the flow, the execution agent runs `get_execute_url` and provides the direct signing link to the chat interface.

Yes. The manager agent monitors the flow status, and once complete, triggers `download_docs` to retrieve the final PDFs for your archives.

All MCP Server tool executions, including retrieving organization info via `get_org_info`, run inside an isolated secure sandbox. Your credentials and contract documents are never exposed to the LLM or external networks.
