Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

This repo is the one-stop shop for building AI-powered products and businesses on top of Stripe.

It contains a collection of SDKs to help you integrate Stripe with LLMs and agent frameworks, including:

  • @stripe/ai-sdk - for integrating Stripe's billing infrastructure with Vercel's `ai` and `@ai-sdk` libraries.
  • @stripe/token-meter - for integrating Stripe's billing infrastructure with native SDKs from OpenAI, Anthropic, and Google Gemini, without any framework dependencies.

Model Context Protocol (MCP)

Stripe hosts a remote MCP server at https://mcp.stripe.com. This allows secure MCP client access via OAuth. View the docs here.

You can also build autonomous agents with MCP as well.

Agent skills

Agent skills are instructions that agents can use to build faster and more accurately. Stripe offers a collection of skills that help your agents use the latest best practices when building with Stripe.

If you use one of these popular agent harnesses, we recommend installing the official Stripe plugins, which include additional agent tools and update automatically.

Questions

What is the Stripe Agent Toolkit MCP server?

One-stop shop for building AI-powered products and businesses with Stripe.

What tools does Stripe Agent Toolkit expose?

9 in total: 8 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Stripe Agent Toolkit safe to connect to an agent?

With care. The audit graded it F (60/100) and found 25 things worth knowing before you trust this server, listed below with the exact line each was found on.

What credentials does Stripe Agent Toolkit need?

It reads ANTHROPIC_API_KEY, GOOGLE_GENERATIVE_AI_API_KEY, NEXTAUTH_URL, NEXT_PUBLIC_STRIPE_PUBLIC_KEY, OPENAI_API_KEY, STRIPE_API_KEY, STRIPE_PUBLISHABLE_KEY, STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Stripe Agent Toolkit run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @stripe/agent-toolkit at 0.9.1.

How current is this page?

The grade is for one exact copy of the source (6262a0e7e4a7), read on 2026-09-26. The repository is watched and re-audited when it changes.
