What it does
Commerce Builder is a Claude Code plugin from Anthropic's reference repository for two commerce agents. Four commands drive the build: `/scaffold-commerce-agent` asks about your stack, plays the plan back and creates a project on the repository packages, `/add-commerce-flow` adds a flow, `/author-commerce-evals` writes checks and `/review-commerce-agent` reviews an existing agent. Six skills give Claude Code reference material: architecture, evals, merchant-operations, prompt-caching, trust-safety and ui-tools. The plugin reads the repository as its model, so you clone it next to your working project. The repository itself holds two agents. The shopping agent searches and compares products, fills the cart, answers order questions and remembers preferences. The merchant agent reads performance numbers, edits listings and reacts to stock, pricing and campaigns. Each of its writes is staged first and a person applies it.
Who it is for. Teams building a Claude-based store assistant or a staff back-office agent who want to start from a tested skeleton.
Good fit when
- Your store app needs an assistant that searches, compares and fills the cart while checkout stays on your site
- Staff need an agent for stock, pricing and campaigns where a person approves every change
- A shopping agent you already have needs a structure review: `/review-commerce-agent` does that
- A store agent needs quality checks and `/author-commerce-evals` writes them from the repository's model
Not a fit when
- You want a ready chat widget for a site: the repository gives a skeleton and your team writes the catalog and order integration
- You need connectors to platforms like Shopify or Stripe: the repository ships no ready MCP connectors
- The agent should charge money or change live listings with no person involved: the example does not do this
Example request
Using commerce-agents as a model, scaffold a shopper assistant for our Python store, starting with search and product detailsLimitations
- The repository is a reference implementation: Anthropic does not maintain it and accepts no contributions.
- The fictional company ACME and four examples (retail, travel, telecom, tickets) show patterns, not finished stores.
- Running the examples needs Python 3.11, Node 22 and `ANTHROPIC_API_KEY`.
- The examples have no authentication and the MCP servers bind to loopback only, so the developer adds protection before anything goes online.
How to disable. `claude plugin uninstall commerce-builder@claude-commerce-agents` removes the plugin. The repository clone can be deleted from your project folder separately.
FAQ
How do I install Commerce Builder in Claude Code?
Run `claude plugin marketplace add anthropics/commerce-agents`, then `claude plugin install commerce-builder@claude-commerce-agents`. Clone the repository next to your project too, because the plugin reads it as its model. After `claude` starts, `/scaffold-commerce-agent` opens with questions about your stack.
Does the agent place orders or charge money?
No. In the examples `checkout` only renders the cart and your site finishes the purchase. Each write by the merchant agent is staged and a person applies it. Payment and authorization rules belong to the deployment.
Does the plugin need an Anthropic key?
The plugin inside Claude Code needs no separate key. Running the demo examples needs `ANTHROPIC_API_KEY` in the `.env` file.
How does the shopping agent differ from the merchant agent?
The shopping agent serves a store customer: it searches products, fills the cart and answers order and policy questions. The merchant agent serves staff: performance, listings, stock, pricing and campaigns. Its changes go through an approval queue.
Where can the built agent run?
The same agent runs through the Messages API, the Claude Agent SDK and Managed Agents. The repository has a separate deployment guide for Vertex AI, Bedrock and Microsoft Foundry.

README in short
The README opens with running four industry demos and building your own agent through the plugin. It then describes the two agents, the package layout and three ways to run: Messages API, Agent SDK and Managed Agents. Separate sections cover safety, verification and deployment on Vertex AI, Bedrock and Foundry. No ready MCP connectors ship; the agents reach your systems through backend interfaces.
