What is the Crystallize MCP MCP server?

Connect Crystallize MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Crystallize headless commerce tools for AI agents via Model Context Protocol. The crystallize mcp mcp server is what makes that connection.

What the server does

MCP server for Crystallize headless commerce. Gives AI agents read and write access to your catalogue, products, shapes, orders, customers, and tenant config — with deep links back to the Crystallize UI, dry-run safety for mutations, and PII masking for customer data.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • browse_catalogue — Traverse the item tree by path
  • get_item — Fetch an item by path or ID with full component data
  • search_catalogue — Keyword search across all items
  • get_product_variants — List variants with pricing and stock
  • list_discovery_shapes — List all shapes with their queryable fields
  • browse_shape — Browse items of a shape with filters, pagination, and field selection
  • get_shape_fields — Detailed field info for a specific shape
  • list_shapes — All shapes with component summaries
  • get_shape — Full component definition for a shape
  • get_tenant_info — Tenant configuration and available languages
  • list_orders — List orders for a customer with pagination
  • get_order — Full order details — cart, payments, customer, totals

Credentials and setup notes

Configuration is passed through the environment: CRYSTALLIZE_TENANT_IDENTIFIER, CRYSTALLIZE_ACCESS_TOKEN_ID, CRYSTALLIZE_ACCESS_TOKEN_SECRET, CRYSTALLIZE_ACCESS_MODE, CRYSTALLIZE_DRY_RUN, CRYSTALLIZE_STATIC_AUTH_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Installation goes through your MCP client rather than a global install: point it at @hayodev/crystallize-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

This sits in the browser automation group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Crystallize MCP's toolset — browse_catalogue, get_item, search_catalogue and 11 more — is a fair guide to whether it matches your workflow. It is maintained by HayoDev; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Crystallize MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Crystallize MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
