Shopify Liquid MCP Server
๐ Fast, local, offline-first MCP server for Shopify Liquid documentation with 198 comprehensive docs including all tags, filters, and objects.
A specialized Model Context Protocol (MCP) server that provides instant access to complete Shopify Liquid documentation for AI assistants like Claude, Cursor, and other MCP-compatible tools.
๐ฏ Why This MCP Server?
vs. Official Shopify MCP
While Shopify provides an official MCP server that covers all Shopify APIs, this server is specifically optimized for Liquid template development:
| Feature | Official Shopify MCP | This (Liquid MCP) | |---------|---------------------|-------------------| | Focus | All Shopify APIs (Admin, Storefront, Functions, etc.) | Liquid templating only | | Storage | Remote (queries shopify.dev) | Local (no network needed) | | Speed | Network-dependent | Instant (<1ms) | | Offline | โ Requires internet | โ Fully offline | | Customization | Fixed documentation | Add your own docs | | Coverage | General API docs | 198 Liquid-specific docs | | Runtime | Node.js | Python |
Use Cases
Use Official Shopify MCP for:
- Admin API/GraphQL development
- App development with Shopify APIs
- Functions and POS extensions
- Real-time schema validation
Use This Liquid MCP for:
- Theme development with Liquid
- Liquid template debugging
- Offline development
- Faster Liquid reference lookups
- Project-specific Liquid snippets
Use Both! They complement each other perfectly - official MCP for APIs, this for Liquid.
