Introduction

This guide walks you through connecting Stripe to AutoGen using the Composio tool router. By the end, you'll have a working Stripe agent that can create a new stripe customer with email, generate a draft invoice for recent orders, cancel an active subscription at period end, issue a refund for a specific payment through natural language commands.

This guide will help you understand how to give your AutoGen agent real control over a Stripe account through Composio's Stripe MCP server.

Before we dive in, let's take a quick look at the key ideas and tools involved.

TL;DR

Here's what you'll learn:
  • Get and set up your OpenAI and Composio API keys
  • Install the required dependencies for Autogen and Composio
  • Initialize Composio and create a Tool Router session for Stripe
  • Wire that MCP URL into Autogen using McpWorkbench and StreamableHttpServerParams
  • Configure an Autogen AssistantAgent that can call Stripe tools
  • Run a live chat loop where you ask the agent to perform Stripe operations

What is AutoGen?

Autogen is a framework for building multi-agent conversational AI systems from Microsoft. It enables you to create agents that can collaborate, use tools, and maintain complex workflows.

Key features include:

  • Multi-Agent Systems: Build collaborative agent workflows
  • MCP Workbench: Native support for Model Context Protocol tools
  • Streaming HTTP: Connect to external services through streamable HTTP
  • AssistantAgent: Pre-built agent class for tool-using assistants

What is the Stripe MCP server, and what's possible with it?

The Stripe MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Stripe account. It provides structured and secure access to your payments platform, so your agent can perform actions like creating customers, managing subscriptions, issuing refunds, and generating invoices on your behalf.

  • Automated customer management: Effortlessly create, update, or delete Stripe customers—enabling streamlined onboarding and account maintenance through your agent.
  • Subscription and recurring billing automation: Have your agent create, configure, or cancel subscriptions, supporting trials, discounts, and advanced billing scenarios with ease.
  • Smart payment and refund processing: Allow your agent to initiate payment intents, confirm transactions, and issue full or partial refunds as needed, all through secure APIs.
  • Seamless invoice and price creation: Generate draft invoices for customers, create new products, and set up pricing structures—saving you time on manual billing tasks.
  • Advanced product and pricing management: Let your agent create new products and prices, helping you roll out new offerings or adjust monetization strategies with just a prompt.

Supported Tools & Triggers

Tools
Triggers
Cancel subscriptionCancels a customer's active stripe subscription at the end of the current billing period, with options to invoice immediately for metered usage and prorate charges for unused time.
Confirm payment intentConfirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
Create CustomerCreates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
Create an invoiceCreates a new draft stripe invoice for a customer; use to revise an existing invoice, bill for a specific subscription (which must belong to the customer), or apply detailed customizations.
Create payment intentCreates a stripe paymentintent to initiate and process a customer's payment; using `application fee amount` for a connected account requires the `stripe-account` header.
Create a priceCreates a new stripe price for a product, defining its charges (one-time or recurring) and billing scheme; requires either an existing `product` id or `product data`.
Create productCreates a new product in stripe, encoding the request as `application/x-www-form-urlencoded` by flattening nested structures.
Create RefundCreates a full or partial refund in stripe, targeting either a specific charge id or a payment intent id.
Create subscriptionCreates a new, highly configurable subscription for an existing stripe customer, supporting multiple items, trials, discounts, and various billing/payment options.
Delete customerPermanently deletes an existing stripe customer; this irreversible action also cancels their active subscriptions and removes all associated data.
List ChargesRetrieves a list of stripe charges with filtering and pagination; use valid cursor ids from previous responses for pagination, and note that charges are typically returned in reverse chronological order.
List Stripe couponsRetrieves a list of discount coupons from a stripe account, supporting pagination via `limit`, `starting after`, and `ending before`.
List customer payment methodsRetrieves a list of payment methods for a given customer, supporting type filtering and pagination.
List customersRetrieves a list of stripe customers, with options to filter by email, creation date, or test clock, and support for pagination.
List InvoicesRetrieves a list of stripe invoices, filterable by various criteria and paginatable using invoice id cursors obtained from previous responses.
List payment intentsRetrieves a list of stripe paymentintents, optionally filtered and paginated using paymentintent ids as cursors.
List payment linksRetrieves a list of payment links from stripe, sorted by creation date in descending order by default.
List productsRetrieves a list of stripe products, with optional filtering and pagination; `starting after`/`ending before` cursors must be valid product ids from a previous response.
List RefundsLists stripe refunds, sorted by creation date descending (newest first), with optional filtering by charge or payment intent and pagination support.
List Stripe shipping ratesRetrieves a list of stripe shipping rates, filterable by active status, creation date, and currency; useful for managing or displaying shipping options.
List subscriptionsRetrieves a list of stripe subscriptions, optionally filtered by various criteria such as customer, price, status, collection method, and date ranges, with support for pagination.
List tax codesRetrieves a paginated list of globally available, predefined stripe tax codes used for classifying products and services in stripe tax.
List tax ratesRetrieves a list of tax rates, which are returned sorted by creation date in descending order.
Retrieve BalanceRetrieves the complete current balance details for the connected stripe account.
Retrieve Charge DetailsRetrieves full details for an existing stripe charge using its unique id.
Retrieve customerRetrieves detailed information for an existing stripe customer using their unique customer id.
Retrieve payment intentRetrieves a paymentintent by its id; `client secret` is required if a publishable api key is used.
Retrieve a refundRetrieves details for an existing stripe refund using its unique `refund id`.
Retrieve subscriptionRetrieves detailed information for an existing stripe subscription using its unique id.
Search Stripe customersRetrieves a list of stripe customers matching a search query that adheres to stripe's search query language.
Update CustomerUpdates an existing stripe customer, identified by customer id, with only the provided details; unspecified fields remain unchanged.
Update Payment IntentUpdates a stripe paymentintent with new values for specified parameters; note that if `currency` is updated, `amount` might also be required, and certain updates (e.
Update SubscriptionUpdates an existing, non-canceled stripe subscription by its id, ensuring all referenced entity ids (e.

What is the Composio tool router, and how does it fit here?

What is Tool Router?

Composio's Tool Router helps agents find the right tools for a task at runtime. You can plug in multiple toolkits (like Gmail, HubSpot, and GitHub), and the agent will identify the relevant app and action to complete multi-step workflows. This can reduce token usage and improve the reliability of tool calls. Read more here: Getting started with Tool Router

The tool router generates a secure MCP URL that your agents can access to perform actions.

How the Tool Router works

The Tool Router follows a three-phase workflow:

  1. Discovery: Searches for tools matching your task and returns relevant toolkits with their details.
  2. Authentication: Checks for active connections. If missing, creates an auth config and returns a connection URL via Auth Link.
  3. Execution: Executes the action using the authenticated connection.

Step-by-step Guide

Prerequisites

You will need:

  • A Composio API key
  • An OpenAI API key (used by Autogen's OpenAIChatCompletionClient)
  • A Stripe account you can connect to Composio
  • Some basic familiarity with Autogen and Python async

Getting API Keys for OpenAI and Composio

OpenAI API Key
  • Go to the OpenAI dashboard and create an API key. You'll need credits to use the models, or you can connect to another model provider.
  • Keep the API key safe.
Composio API Key
  • Log in to the Composio dashboard.
  • Navigate to your API settings and generate a new API key.
  • Store this key securely as you'll need it for authentication.

Install dependencies

bash
pip install composio python-dotenv
pip install autogen-agentchat autogen-ext-openai autogen-ext-tools

Install Composio, Autogen extensions, and dotenv.

What's happening:

  • composio connects your agent to Stripe via MCP
  • autogen-agentchat provides the AssistantAgent class
  • autogen-ext-openai provides the OpenAI model client
  • autogen-ext-tools provides MCP workbench support

Set up environment variables

bash
COMPOSIO_API_KEY=your-composio-api-key
OPENAI_API_KEY=your-openai-api-key
USER_ID=your-user-identifier@example.com

Create a .env file in your project folder.

What's happening:

  • COMPOSIO_API_KEY is required to talk to Composio
  • OPENAI_API_KEY is used by Autogen's OpenAI client
  • USER_ID is how Composio identifies which user's Stripe connections to use

Import dependencies and create Tool Router session

python
import asyncio
import os
from dotenv import load_dotenv
from composio import Composio

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

load_dotenv()

async def main():
    # Initialize Composio and create a Stripe session
    composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY"))
    session = composio.create(
        user_id=os.getenv("USER_ID"),
        toolkits=["stripe"]
    )
    url = session.mcp.url
What's happening:
  • load_dotenv() reads your .env file
  • Composio(api_key=...) initializes the SDK
  • create(...) creates a Tool Router session that exposes Stripe tools
  • session.mcp.url is the MCP endpoint that Autogen will connect to

Configure MCP parameters for Autogen

python
# Configure MCP server parameters for Streamable HTTP
server_params = StreamableHttpServerParams(
    url=url,
    timeout=30.0,
    sse_read_timeout=300.0,
    terminate_on_close=True,
    headers={"x-api-key": os.getenv("COMPOSIO_API_KEY")}
)

Autogen expects parameters describing how to talk to the MCP server. That is what StreamableHttpServerParams is for.

What's happening:

  • url points to the Tool Router MCP endpoint from Composio
  • timeout is the HTTP timeout for requests
  • sse_read_timeout controls how long to wait when streaming responses
  • terminate_on_close=True cleans up the MCP server process when the workbench is closed

Create the model client and agent

python
# Create model client
model_client = OpenAIChatCompletionClient(
    model="gpt-5",
    api_key=os.getenv("OPENAI_API_KEY")
)

# Use McpWorkbench as context manager
async with McpWorkbench(server_params) as workbench:
    # Create Stripe assistant agent with MCP tools
    agent = AssistantAgent(
        name="stripe_assistant",
        description="An AI assistant that helps with Stripe operations.",
        model_client=model_client,
        workbench=workbench,
        model_client_stream=True,
        max_tool_iterations=10
    )

What's happening:

  • OpenAIChatCompletionClient wraps the OpenAI model for Autogen
  • McpWorkbench connects the agent to the MCP tools
  • AssistantAgent is configured with the Stripe tools from the workbench

Run the interactive chat loop

python
print("Chat started! Type 'exit' or 'quit' to end the conversation.\n")
print("Ask any Stripe related question or task to the agent.\n")

# Conversation loop
while True:
    user_input = input("You: ").strip()

    if user_input.lower() in ["exit", "quit", "bye"]:
        print("\nGoodbye!")
        break

    if not user_input:
        continue

    print("\nAgent is thinking...\n")

    # Run the agent with streaming
    try:
        response_text = ""
        async for message in agent.run_stream(task=user_input):
            if hasattr(message, "content") and message.content:
                response_text = message.content

        # Print the final response
        if response_text:
            print(f"Agent: {response_text}\n")
        else:
            print("Agent: I encountered an issue processing your request.\n")

    except Exception as e:
        print(f"Agent: Sorry, I encountered an error: {str(e)}\n")
What's happening:
  • The script prompts you in a loop with You:
  • Autogen passes your input to the model, which decides which Stripe tools to call via MCP
  • agent.run_stream(...) yields streaming messages as the agent thinks and calls tools
  • Typing exit, quit, or bye ends the loop

if __name__ == "__main__":
    asyncio.run(main())

Conclusion

You now have an Autogen assistant wired into Stripe through Composio's Tool Router and MCP. From here you can:
  • Add more toolkits to the toolkits list, for example notion or hubspot
  • Refine the agent description to point it at specific workflows
  • Wrap this script behind a UI, Slack bot, or internal tool
Once the pattern is clear for Stripe, you can reuse the same structure for other MCP-enabled apps with minimal code changes.

How to build Stripe MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Stripe MCP?

With a standalone Stripe MCP server, the agents and LLMs can only access a fixed set of Stripe tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Stripe and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Autogen?

Yes, you can. Autogen fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Stripe tools.

Can I manage the permissions and scopes for Stripe while using Tool Router?

Yes, absolutely. You can configure which Stripe scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Stripe data and credentials are handled as safely as possible.
