--- Stop AI coding tools from breaking your data files. No more grep guesswork, hallucinated fields, or non-schema-compliant data added to files. This MCP server gives AI assistants a strict, round-trip safe interface for working with structured data. ## The Problem AI coding tools often destroy structured data files: - They **grep** through huge json, yaml, and toml files (like json logs, or AI transcript files) and guess at keys. - They **hallucinate** fields that never existed. - They use **sed and regex** that leave files in invalid states. - They break **YAML indentation** and **TOML syntax**. - They can't **validate** changes before writing. ## The Solution **mcp-json-yaml-toml** provides AI assistants with proper tools for structured data: - **Token-efficient**: Extract exactly what you need without loading entire files. - **Schema validation**: Enforce correctness using SchemaStore.or
