How to Use the Mailgun (Transactional Email & Domains) MCP in AutoGen

Q: How do I configure the Mailgun (Transactional Email & Domains) MCP Server for AutoGen?

Use the mcpservertools function with the Streamable HTTP transport. Pass the resulting tool list directly into your AssistantAgent constructor.

Q: Can the agents read HTML templates?

They can. An agent can call gettemplates to see what layouts are available on your account, then debate which template best fits the current notification context.

Give your AutoGen agents the tools to debate, send, and audit transactional emails autonomously.

Perplexity

Multi-agent delivery orchestration

This MCP Server lets your AutoGen agents negotiate email operations. A copywriter agent drafts a message and proposes sending it. A compliance agent intercepts the request, runs `validate_email`, and checks `list_unsubscribes` before approving the dispatch. They debate the results. If the validation score is borderline, the agents decide together whether to risk the sender reputation or drop the contact entirely. Once they reach consensus, they trigger `send_email`.

Autonomous bounce resolution

Set up a specialized infrastructure agent to monitor your suppression lists using the MCP Server. When it finds a new hard bounce via `list_bounces`, it alerts a support agent to review the customer's account status. The support agent might notice a typo in the address. It fixes the record in your database, instructs the infrastructure agent to execute `delete_bounce`, and attempts a fresh delivery.

Audit campaigns via MCP Server

Your agents pull analytics and investigate anomalies without human intervention. An analyst agent calls `get_stats` to review the morning's open rates. If the numbers dip, it immediately asks a diagnostic agent to pull `list_logs`. The diagnostic agent scans the raw event data for spam blocks or DNS failures. It cross-references the findings by calling `get_domain` to verify the SPF and DKIM records are still intact.

Setup guide

Set up Mailgun (Transactional Email & Domains) 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 Mailgun (Transactional Email & Domains) 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="Mailgun (Transactional Email & Domains)_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Mailgun (Transactional Email & Domains) 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="Mailgun (Transactional Email & Domains)_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Mailgun (Transactional Email & Domains) data")
    print(result.messages[-1].content)

Common questions about Mailgun (Transactional Email & Domains) MCP in AutoGen

Use the `mcp_server_tools` function with the Streamable HTTP transport. Pass the resulting tool list directly into your `AssistantAgent` constructor.

Yes. You can equip different agents with different toolsets. Give your support agent access to logs and bounces, while restricting your marketing agent to just template retrieval and sending.

When an API call fails, the agent receives the error string. It can then discuss the failure with a debugging agent to figure out if it needs to retry the request or change the input parameters.

They can. An agent can call `get_templates` to see what layouts are available on your account, then debate which template best fits the current notification context.

Auth tokens and API keys are handled entirely outside the execution environment. When your agents pull sensitive subscriber data and unsubscription lists, the isolated sandbox processes the request and self-destructs immediately.
