What is Stripe Model Context Protocol

The Stripe Agent Toolkit is a library that facilitates integration with Stripe APIs using popular agent frameworks such as OpenAI’s Agent SDK, LangChain, CrewAI, Vercel’s AI SDK, and the Model Context Protocol (MCP). It is designed for both Python and TypeScript, providing functionalities built on top of the official Stripe SDKs.

Use cases

The toolkit can be used to automate tasks involving payment processing, customer management, invoicing, and subscription management in Stripe. It supports creating customers, products, prices, payment links, invoices, and refunds, making it useful for businesses that require programmatic access to Stripe’s services.

How to use

To use the Stripe Agent Toolkit, install the appropriate package for your programming language (Python or TypeScript), configure it with your Stripe secret key, and define the actions you intend to perform. For example, create instances of the toolkit and pass them as tools to agent frameworks, allowing you to execute various Stripe API calls.

Key features

Key features include the ability to create and manage customers, products, prices, payment links, and subscriptions. The toolkit also supports context management for connected accounts, middleware for billing events, and interactions with various agent frameworks, enhancing automation and billing capabilities.

Where to use

The toolkit can be used in any application that requires integration with Stripe for payment processing and financial operations. It is particularly applicable in e-commerce platforms, subscription services, and any software that requires automated handling of customer and payment-related tasks.

Stripe Agent Toolkit

The Stripe Agent Toolkit enables popular agent frameworks including OpenAI’s Agent SDK, LangChain, CrewAI, Vercel’s AI SDK, and Model Context Protocol (MCP) to integrate with Stripe APIs through function calling. The
library is not exhaustive of the entire Stripe API. It includes support for both Python and TypeScript and is built directly on top of the Stripe Python and Node SDKs.

Included below are basic instructions, but refer to the Python and TypeScript packages for more information.

Python

Installation

You don’t need this source code unless you want to modify the package. If you just
want to use the package run:

pip install stripe-agent-toolkit

Requirements

• Python 3.11+

Usage

The library needs to be configured with your account’s secret key which is
available in your Stripe Dashboard.

from stripe_agent_toolkit.openai.toolkit import StripeAgentToolkit

stripe_agent_toolkit = StripeAgentToolkit(
    secret_key="sk_test_...",
    configuration={
        "actions": {
            "payment_links": {
                "create": True,
            },
        }
    },
)

The toolkit works with OpenAI’s Agent SDK, LangChain, and CrewAI and can be passed as a list of tools. For example:

from agents import Agent

stripe_agent = Agent(
    name="Stripe Agent",
    instructions="You are an expert at integrating with Stripe",
    tools=stripe_agent_toolkit.get_tools()
)

Examples for OpenAI’s Agent SDK,LangChain, and CrewAI are included in /examples.

Context

In some cases you will want to provide values that serve as defaults when making requests. Currently, the account context value enables you to make API calls for your connected accounts.

stripe_agent_toolkit = StripeAgentToolkit(
    secret_key="sk_test_...",
    configuration={
        "context": {
            "account": "acct_123"
        }
    }
)

TypeScript

Installation

You don’t need this source code unless you want to modify the package. If you just
want to use the package run:

npm install @stripe/agent-toolkit

Requirements

• Node 18+

Usage

The library needs to be configured with your account’s secret key which is available in your Stripe Dashboard. Additionally, configuration enables you to specify the types of actions that can be taken using the toolkit.

import { StripeAgentToolkit } from "@stripe/agent-toolkit/langchain";

const stripeAgentToolkit = new StripeAgentToolkit({
  secretKey: process.env.STRIPE_SECRET_KEY!,
  configuration: {
    actions: {
      paymentLinks: {
        create: true,
      },
    },
  },
});

Tools

The toolkit works with LangChain and Vercel’s AI SDK and can be passed as a list of tools. For example:

import { AgentExecutor, createStructuredChatAgent } from "langchain/agents";

const tools = stripeAgentToolkit.getTools();

const agent = await createStructuredChatAgent({
  llm,
  tools,
  prompt,
});

const agentExecutor = new AgentExecutor({
  agent,
  tools,
});

Context

In some cases you will want to provide values that serve as defaults when making requests. Currently, the account context value enables you to make API calls for your connected accounts.

const stripeAgentToolkit = new StripeAgentToolkit({
  secretKey: process.env.STRIPE_SECRET_KEY!,
  configuration: {
    context: {
      account: "acct_123",
    },
  },
});

Metered billing

For Vercel’s AI SDK, you can use middleware to submit billing events for usage. All that is required is the customer ID and the input/output meters to bill.

import { StripeAgentToolkit } from "@stripe/agent-toolkit/ai-sdk";
import { openai } from "@ai-sdk/openai";
import {
  generateText,
  experimental_wrapLanguageModel as wrapLanguageModel,
} from "ai";

const stripeAgentToolkit = new StripeAgentToolkit({
  secretKey: process.env.STRIPE_SECRET_KEY!,
  configuration: {
    actions: {
      paymentLinks: {
        create: true,
      },
    },
  },
});

const model = wrapLanguageModel({
  model: openai("gpt-4o"),
  middleware: stripeAgentToolkit.middleware({
    billing: {
      customer: "cus_123",
      meters: {
        input: "input_tokens",
        output: "output_tokens",
      },
    },
  }),
});

Model Context Protocol

The Stripe Agent Toolkit also supports the Model Context Protocol (MCP).

To run the Stripe MCP server using npx, use the following command:

npx -y @stripe/mcp --tools=all --api-key=YOUR_STRIPE_SECRET_KEY

Replace YOUR_STRIPE_SECRET_KEY with your actual Stripe secret key. Or, you could set the STRIPE_SECRET_KEY in your environment variables.

Alternatively, you can set up your own MCP server. For example:

import { StripeAgentToolkit } from "@stripe/agent-toolkit/modelcontextprotocol";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

const server = new StripeAgentToolkit({
  secretKey: process.env.STRIPE_SECRET_KEY!,
  configuration: {
    actions: {
      paymentLinks: {
        create: true,
      },
      products: {
        create: true,
      },
      prices: {
        create: true,
      },
    },
  },
});

async function main() {
  const transport = new StdioServerTransport();
  await server.connect(transport);
  console.error("Stripe MCP Server running on stdio");
}

main().catch((error) => {
  console.error("Fatal error in main():", error);
  process.exit(1);
});
