How to Use the Fastn MCP in AutoGen

Q: How do I load Fastn tools into my AutoGen agents?

Install autogen-extmcp and use mcpservertools with your server URL. Pass the loaded MCP Server tools directly into your AssistantAgent constructor.

Q: Can AutoGen agents collaborate to debug a failed Fastn execution?

Yes. One agent can call listexecutions to find failures, while another calls getexecution to analyze the error logs and propose fixes.

Q: How do AutoGen agents manage API limits when running Fastn workflows?

Your agents can query getquotausage and getquotadaily to check resource limits. They negotiate how to distribute the remaining quota across pending tasks.

Build multi-agent AutoGen conversations that collaborate to run, monitor, and optimize your Fastn workflows using this MCP Server.

Fastn MCP Server execution via multi-agent debate

Fastn MCP Server tools allow your AutoGen agents to coordinate complex backend actions. One agent plans the execution steps, while another calls `execute_flow` to run the actual task. A third agent can monitor the progress by calling `get_execution`. If things go wrong, the agents debate the failure reason and use `cancel_execution` to stop runaway processes.

Automated credential rotation via agent consensus

Your security agent manages access keys programmatically using `store_credentials` and `rotate_credentials`. The security agent coordinates with your operational agent to update expired keys without manual intervention. Before updating, the agent checks `get_credentials` to confirm which connector needs attention. This ensures your automated flows never fail due to expired third-party API keys.

Dynamic workflow optimization and deployment

Your agents get the ability to write and deploy code-free automations on the fly using `create_workflow` and `update_workflow`. The developer agent drafts the new flow structure, and the QA agent reviews it. Once both agents reach consensus, they run `publish_workflow` to push the changes live. Old versions are cleaned up using `archive_workflow` to maintain a tidy workspace.

Setup guide

Set up Fastn 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 Fastn 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="Fastn_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

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

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

Yes. Your agents can draft definitions, write them using create_workflow, and then deploy them live to production using publish_workflow.

Raw secrets never enter the agent conversation logs. The MCP Server uses store_credentials and rotate_credentials to manage keys within Fastn's sandboxed environment, keeping your credentials isolated from the chat history.
