@brainerce/mcp-server

Framework-agnostic domain knowledge for building on Brainerce, a headless commerce platform. This MCP server answers questions an AI coding assistant needs while building or extending a Brainerce-powered storefront — SDK reference, type definitions, business-flow sequencing, critical rules, and a given store's live capabilities.

It does not generate framework boilerplate. Use Next.js, Remix, Vite + React, Vue, Svelte, Astro, SolidStart, or whatever the surrounding project already uses — this server tells the agent what to build correctly, not how to lay out files. For opinionated scaffolding, see the companion create-brainerce-store CLI.

Install

Claude Code (plugin):

claude plugin install brainerce-mcp@claude-plugins-community

Any MCP client (stdio, manual config):

{
  "mcpServers": {
    "brainerce": {
      "command": "npx",
      "args": ["-y", "@brainerce/mcp-server"]
    }
  }
}

Tools

| Tool | Purpose | | --- | --- | | get-store-capabilities | Live features configured for a specific store (payment providers, OAuth, discounts, shipping, i18n). Call first — it tells the agent which conditional features to build. | | get-required-features | Functional coverage checklist — what users must be able to do, not which files to create. Mandatory features must exist even when currently disabled in the store (they auto-hide; owners enable them later). | | get-critical-rules | Do's and don'ts that cause production incidents if violated — SDK usage, auth token handling, checkout invariants, i18n, type safety. | | get-business-flows | Non-negotiable ordered SDK call sequences: checkout, auth, password reset, OAuth, order confirmation, cart persistence, inventory reservation. | | get-sdk-docs | SDK documentation by topic — setup, API usage, best practices. | | get-type-definitions | TypeScript types for Product, Cart, Checkout, Order, etc. | | get-code-example | Short, focused snippets for tricky SDK calls (payment confirmation, reservation countdown, OAuth redirect, variant selection). | | get-store-info | Live store metadata (display name, currency, language) for a sales channel. | | get-integration-guide | Step-by-step integration walkthrough — core (products/cart/checkout/payment/orders), optional (accounts/OAuth/promotions), or rules (validation/error codes/edge cases). |

Resources

• sdk-types — the full Brainerce SDK type surface as a text resource.

Prompts

• create-store — framework-agnostic brief for building a new Brainerce-powered store; instructs the agent to call the knowledge tools above before writing code.
• add-feature — focused prompt for adding one feature to an existing Brainerce store.

Self-hosting

pnpm build
pnpm start:stdio   # stdio transport, for local MCP clients
pnpm start:http    # Streamable HTTP + legacy SSE, for remote clients (default port 3100)

The HTTP server is a public, unauthenticated documentation oracle by design — everything behind it is public SDK/docs data. It applies allow-listed CORS, per-IP rate limiting, request size caps, and SSE session limits; see src/bin/http.ts for details.

Privacy

This server serves static SDK documentation and, for the store-scoped tools (get-store-info, get-store-capabilities, get-required-features), reads public store configuration via Brainerce's public API. It does not collect or store conversation data. See brainerce.com/privacy for the full policy.
