Crystallize MCP
Operate Crystallize headless commerce catalog, discovery, and authenticated APIs from your AI agent via MCP.
Overview
Crystallize MCP is an MCP server for the Build phase that exposes Crystallize headless commerce catalog and API tools to AI agents.
What is this MCP server?
- Headless commerce operations for AI agents over MCP
- Tenant-scoped tools via CRYSTALLIZE_TENANT_IDENTIFIER
- Optional access token ID/secret or static read-only auth token
- Public catalogue and Discovery API usable without full auth
- npm stdio @hayodev/crystallize-mcp 0.2.0 via npx
- npm @hayodev/crystallize-mcp version 0.2.0
- Public catalogue and Discovery API work without auth per server docs
- stdio transport via npx runtimeHint
What problem does it solve?
Agents cannot safely manage your Crystallize store if every product query requires custom GraphQL scripts outside MCP.
Who is it for?
Builders shipping headless or composable commerce who already use Crystallize and want agent-driven catalog and API tasks.
Skip if: Shopify-only stacks, non-commerce apps, or teams that need a full storefront theme without Crystallize.
What do I get? / Deliverables
After tenant and token setup, your agent can call Crystallize commerce tools through a standard MCP stdio server.
- Agent-callable Crystallize commerce MCP tools
- Catalogue and Discovery API access scoped to tenant
- Authenticated commerce operations when tokens are configured
