JSON Schema Store MCP — catalog of JSON Schemas for hundreds of well-known config/data file formats (package.json, tsconfig.json, GitHub Actions workflows, OpenAPI, etc). Keyless.

Tools

• list_schemas(filter?, limit?) — list catalog entries; filter is a case-insensitive substring on name/description/fileMatch
• find_schema_for(filename) — find schemas that match a given filename (e.g. package.json, .github/workflows/ci.yml)
• fetch_schema(url) — fetch the raw JSON Schema document from the catalog (schemastore-hosted URL)
• lookup(name) — exact-name lookup against the catalog
