Introduction

This guide walks you through connecting Stripe to CrewAI 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 CrewAI 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 a Composio API key and configure your Stripe connection
  • Set up CrewAI with an MCP enabled agent
  • Create a Tool Router session or standalone MCP server for Stripe
  • Build a conversational loop where your agent can execute Stripe operations

What is CrewAI?

CrewAI is a powerful framework for building multi-agent AI systems. It provides primitives for defining agents with specific roles, creating tasks, and orchestrating workflows through crews.

Key features include:

  • Agent Roles: Define specialized agents with specific goals and backstories
  • Task Management: Create tasks with clear descriptions and expected outputs
  • Crew Orchestration: Combine agents and tasks into collaborative workflows
  • MCP Integration: Connect to external tools through Model Context Protocol

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

Before starting, make sure you have:
  • Python 3.9 or higher
  • A Composio account and API key
  • A Stripe connection authorized in Composio
  • An OpenAI API key for the CrewAI LLM
  • Basic familiarity with Python

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 crewai crewai-tools python-dotenv
What's happening:
  • composio connects your agent to Stripe via MCP
  • crewai provides Agent, Task, Crew, and LLM primitives
  • crewai-tools includes MCP helpers
  • python-dotenv loads environment variables from .env

Set up environment variables

bash
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_here
OPENAI_API_KEY=your_openai_api_key_here

Create a .env file in your project root.

What's happening:

  • COMPOSIO_API_KEY authenticates with Composio
  • USER_ID scopes the session to your account
  • OPENAI_API_KEY lets CrewAI use your chosen OpenAI model

Import dependencies

python
from crewai import Agent, Task, Crew, LLM
from crewai_tools import MCPServerAdapter  # optional import if you plan to adapt tools
from composio import Composio
from dotenv import load_dotenv
import os
from crewai.mcp import MCPServerHTTP

load_dotenv()
What's happening:
  • CrewAI classes define agents and tasks, and run the workflow
  • MCPServerHTTP connects the agent to an MCP endpoint
  • Composio will give you a short lived Stripe MCP URL

Create a Composio Tool Router session for Stripe

python
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:
  • You create a Stripe only session through Composio
  • Composio returns an MCP HTTP URL that exposes Stripe tools

Configure the LLM

python
llm = LLM(
    model="gpt-5-mini",
    api_key=os.getenv("OPENAI_API_KEY"),
)
What's happening:
  • CrewAI will call this LLM for planning and responses
  • You can swap in a different model if needed

Attach the MCP server and create the agent

python
toolkit_agent = Agent(
    role="Stripe Assistant",
    goal="Help users interact with Stripe through natural language commands",
    backstory=(
        "You are an expert assistant with access to Stripe tools. "
        "You can perform various Stripe operations on behalf of the user."
    ),
    mcps=[
        MCPServerHTTP(
            url=url,
            streamable=True,
            cache_tools_list=True,
            headers={"x-api-key": os.getenv("COMPOSIO_API_KEY")},
        ),
    ],
    llm=llm,
    verbose=True,
    max_iter=10,
)
What's happening:
  • MCPServerHTTP connects the agent to the Stripe MCP endpoint
  • cache_tools_list saves a tools catalog for faster subsequent runs
  • verbose helps you see what the agent is doing

Add a REPL loop with Task and Crew

python
print("Chat started! Type 'exit' or 'quit' to end.\n")
print("Try asking the agent to perform Stripe operations.\n")

conversation_context = ""

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

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

    if not user_input:
        continue

    conversation_context += f"\nUser: {user_input}\n"
    print("\nAgent is thinking...\n")

    task = Task(
        description=(
            f"Based on the conversation history:\n{conversation_context}\n\n"
            f"Current user request: {user_input}\n\n"
            f"Please help the user with their Stripe related request."
        ),
        expected_output="A helpful response addressing the user's request",
        agent=toolkit_agent,
    )

    crew = Crew(
        agents=[toolkit_agent],
        tasks=[task],
        verbose=False,
    )

    result = crew.kickoff()
    response = str(result)

    conversation_context += f"Agent: {response}\n"
    print(f"Agent: {response}\n")
What's happening:
  • You build a simple chat loop and keep a running context
  • Each user turn becomes a Task handled by the same agent
  • Crew executes the task and returns a response

Run the application

python
if __name__ == "__main__":
    main()
What's happening:
  • Standard Python entry point so you can run python crewai_stripe_agent.py

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 CrewAI?

Yes, you can. CrewAI 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.
