How to Use the EasyPost MCP in AutoGen

Q: How do I register the EasyPost server tools with AutoGen agents?

Install autogen-extmcp and use mcpservertools with the Vinkius HTTP URL. Pass the generated tools list directly into your AssistantAgent constructor.

Q: Can AutoGen agents handle shipping exceptions using EasyPost?

Yes. An agent can run searchbytrackingcode to find a failing shipment, then hand the tracking events to a resolver agent to notify the carrier.

Q: How do I check if a tracker is already active?

Run listactivetrackers to see all current tracking objects. This prevents your agents from creating duplicate tracking requests.

Let your AutoGen agents debate shipping options and carrier rates using this EasyPost MCP Server.

Multi-agent carrier negotiation in AutoGen

The `list_carrier_accounts` tool lists all connected shipping accounts to let your agents compare active contracts. This tool gives your group chat the raw carrier list needed to start a cost debate. One agent runs `get_shipment_details` to pull current rates, while another checks historical performance. They negotiate the best option in the chat, removing human intervention from the shipping decision.

Automate tracking audits with AutoGen groups

The `list_in_transit_packages` tool identifies every package currently moving through carrier networks. This tool acts as the trigger for your automated auditing conversation. Look, here's the deal. Your tracking agent runs `get_tracking_details` on flagged shipments, while a customer-service agent drafts updates. They resolve shipping delays together without writing custom glue code.

Monitor account health via this MCP Server

The `get_easypost_account_metadata` tool pulls your current account usage limits and metadata. Your manager agent checks this tool to ensure your budget isn't blown. Run `quick_delivery_health_audit` alongside it to get a complete view of your shipping health. This keeps your multi-agent system informed of operational constraints before executing new shipments.

Setup guide

Set up EasyPost 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 EasyPost 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="EasyPost_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent EasyPost 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="EasyPost_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

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