Shopify Liquid MCP Server

🚀 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.

🎯 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	❌ Requires internet	✅ 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.

✨ Features

🚀 Lightning Fast - Local SQLite FTS5 search (<1ms response time)
📚 Complete Coverage - 30 tags, 101 filters, 67 objects (198 total docs)
🔌 Offline First - No network requests, works anywhere
🐳 Docker Ready - One command deployment
🎨 IDE Integration - Works with VS Code, Cursor, Claude Desktop, Zed
🔧 Customizable - Add your own project-specific Liquid docs
📖 Rich Documentation - Full syntax, parameters, examples for everything
🔍 Smart Search - Full-text search with snippet highlighting
