Guidance Lark Mcp

Guidance Lark Mcp is a Model Context Protocol (MCP) server for building, validating, and batch-testing Lark grammars that are compatible with llguidance—a framework for AI-assisted grammar-based generation. It exposes tools to validate grammar definitions, execute batch validation tests, retrieve up-to-date grammar syntax documentation, and optionally generate text constrained by grammar rules using LLMs like OpenAI or Azure OpenAI. This MCP server integrates with environments such as GitHub Copilot CLI, VS Code, and Claude Desktop, and is designed for developers, AI engineers, and anyone building structured grammars or tools that interface with LLMs using precise parsing or generation constraints.
