MCPatterns is an MCP server that lets you save and retrieve personalized coding patterns. It acts as a persistent memory layer for your LLM agents, helping them adopt your coding style, patterns, and conventions across sessions and projects.

How to use

You interact with MCPatterns through an MCP client to create, read, update, and search for patterns. Organize patterns by category and technology, then reference these patterns during code generation, refactoring, or style suggestions. Use the provided tools to add new patterns, attach code examples in multiple languages, and retrieve patterns that match your current tech stack and use case.

How to install

Prerequisites: Node.js and a modern package manager (npm or pnpm) installed on your system.

# Clone the project
git clone https://github.com/nicholasrubright/mcpatterns.git
cd mcpatterns

# Install dependencies
pnpm install

# Development server (hot reloading)
pnpm run dev

# Build for production
pnpm run build

# Run the server
pnpm start

Additional setup for MCP client integration

There are ready-to-use MCP client integrations that let you connect MCPatterns to your tooling. The following configurations show how to run the MCP server locally with a standard MCP command and how to inject a custom storage path for the patterns database.

Configuration and integration details

Environment variables let you customize where the patterns data is stored and how the server is invoked by MCP clients.

Notes on usage

Use descriptive names and categorize patterns consistently to improve searchability. - Store focused, single-purpose patterns with rich metadata and multiple language examples when applicable. - Keep code examples up-to-date with current practices and make them easy to reuse in future sessions.
