Grimoire MCP

What it does

Grimoire-MCP transforms your coding assistant into a knowledge curator by allowing it to save and retrieve software development patterns. It manages a local library of reusable code best practices stored as markdown files with YAML frontmatter, ensuring your hard-won architectural insights are always available to your LLM.

Tools

• list_patterns: Lists all available patterns in the library.
• search_patterns: Search patterns by query, category, framework, or tag.
• get_pattern: Retrieves the full content of a specific pattern by name.
• create_pattern: Saves a new pattern including metadata and content to the filesystem.

Installation

Requires the PATTERNS_DIR environment variable to be set to your desired storage directory.
