Common questions

Is Spree Commerce: open-source B2B and marketplace ecommerce safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed today, and the latest version (6.0.1) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Spree MCP Server

A Model Context Protocol server for the Spree back office. Any MCP client — Claude Code, Cursor, an in-house agent — can merchandise the catalog, answer reporting questions and manage store setup in plain language, under the same tenancy and permission rules as the Admin API.

spree add mcp   # or add gem 'spree_mcp' to the Gemfile

The endpoint is POST /api/v3/admin/mcp, authenticated with a Spree secret API key sent as X-Spree-API-Key: sk_… or Authorization: Bearer sk_…. The key's scopes decide which tools the model is offered, so an agent is never told about a capability its credential does not carry.

This gem is a protocol adapter and nothing more. The tools, their schemas and the permissions gating them live in spree_core as Spree.admin_agent_tools, which means an extension registers a tool without depending on this gem, and the dashboard assistant offers the same tools over a different transport.

See the documentation and docs/plans/6.0-mcp-server.md.
