Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢validate_jsonld(input, include_raw)
Validate JSON-LD structured data against the Schema.org vocabulary. Accepts raw JSON-LD or an HTML snippet/page containing <script type="application/ld+json"> blocks (pass the text, not a URL: this tool never fetches anything). Returns valid true/false, error/warning/info counts, the Schema.org types found, and up to 25 issues with JSON paths, messages and did-you-mean suggestions. Read-only. Same engine as the RichProof JSON API (POST /api/validate).
