How to Use the Mailinator MCP in AutoGen

Q: How do I register Mailinator tools with an AutoGen agent?

Use the mcpservertools helper from autogen-extmcp to load the server. Pass the tools list to your AssistantAgent constructor to give your AutoGen agents access to endpoints like listinboxmessages.

Q: How does AutoGen handle schema conversion for Mailinator tools?

The McpToolAdapter automatically translates the server schema into the format AutoGen expects. Your AutoGen agents can call getmessagecontent without you writing custom wrapper code.

Q: Can I test SMS workflows with this server?

Yes, you can use listprivatesms to retrieve SMS messages sent to your private numbers. This allows your AutoGen agents to verify multi-factor authentication codes and text notification templates.

Deploy AutoGen agents that debate, verify, and clean up disposable Mailinator inboxes during automated QA cycles.

Perplexity

Verify emails with an AutoGen MCP Server

AutoGen agents can collaborate to solve complex testing scenarios. For instance, a QA agent calls `list_inbox_messages` to retrieve incoming Mailinator messages, while a separate validation agent inspects the content. If the AutoGen validation agent flags an anomaly using `get_message_content`, it can debate the issue with the QA agent. The AutoGen agents negotiate whether the Mailinator test failed or if a retry is needed before making a final report.

Simulate real-world email traffic autonomously

Your AutoGen agents can generate their own test scenarios on the fly. A coordinator agent calls `inject_test_message` to simulate an incoming customer email with specific headers. A second AutoGen agent watches the inbox and uses `extract_message_links` to process the incoming payload. This AutoGen multi-agent setup replicates real user behavior without requiring manual Mailinator test scripts.

Manage private domains and clean up inboxes

Keeping a Mailinator test environment clean requires coordination. One AutoGen agent can monitor inbox health using `get_usage_statistics` while another manages domain configurations. After verifying an AutoGen test flow, a cleanup agent calls `remove_message` to purge the Mailinator inbox. This ensures subsequent AutoGen test runs start with a clean Mailinator slate, preventing false positives from old emails.

Setup guide

Set up Mailinator 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 Mailinator 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="Mailinator_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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

Common questions about Mailinator MCP in AutoGen

Use the `mcp_server_tools` helper from `autogen-ext[mcp]` to load the server. Pass the tools list to your `AssistantAgent` constructor to give your AutoGen agents access to endpoints like `list_inbox_messages`.

Yes, agents can share the toolset. One AutoGen agent can call `list_private_domains` to find active routing rules, while another runs `list_active_webhooks` to monitor incoming notifications.

The `McpToolAdapter` automatically translates the server schema into the format AutoGen expects. Your AutoGen agents can call `get_message_content` without you writing custom wrapper code.

Yes, you can use `list_private_sms` to retrieve SMS messages sent to your private numbers. This allows your AutoGen agents to verify multi-factor authentication codes and text notification templates.

No, Vinkius executes the server in a zero-trust, ephemeral sandbox. The text content, attachments, and SMS data retrieved from your Mailinator account are only held in memory during the active session.
