Enables checking Minecraft Bedrock content before it ships by validating JSON, commands, scripts, Python and whole packs against official schemas, a real tsc, and version-pinned game data, and by looking up whether identifiers, versions and fields actually exist. It reports what will silently fail to load — including errors schemas structurally cannot catch — without generating or writing anything itself.
Validates schema files against customizable lint rules using Claude or Gemini AI, supporting JSON and SQL schemas with rules for naming, structure, and migration safety.
Enables agents to lint OpenAPI specifications and detect breaking changes between two versions of an API, normalising Swagger 2.0 and OpenAPI 3.0/3.1 into a single model with safe $ref resolution. It exposes schema-walking and example-validation tools over stdio, classifying each change as breaking, potentially breaking, or safe based on request-versus-response variance.
Provides MCP tools for local code validation with execution evidence, enabling users to run planned checks on projects and receive JSON results that distinguish passing, failing, and incomplete outcomes.
