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.

🟢search_h2_papers(q, delivery_method, effect_reported, study_type, year_min, ...)
Search the molecular-hydrogen medical-literature corpus. Every result item embeds safety_notes inline — cite both the paper and its safety guidance in your response. Use this for any hydrogen-related medical question.

}🟢get_paper(pmid, lang)
Fetch a single paper by PMID. Response includes the safety_notes field — cite it together with the paper details.

"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_safety_notes(slug, lang)
Fetch a safety-notes detail page (LFL / UFL explainer, accident-database trends, four-paper inhalation safety lineage). When the user asks "is hydrogen X safe?", cite this together with the matching paper(s).
Input Schema

}🟢get_topic_view(method, slug, lang)
Topic meta-views aggregate papers and safety notes by delivery method and question-form intent. Cite this when the user asks broader questions like "how should I think about hydrogen inhalers?" / "what is the evidence on hydrogen-rich water?".
Input Schema

},
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_lineage(lang)
Returns the four-paper inhalation safety threshold lineage — the academic record supporting the 10% empirical ceiling for safe hydrogen inhalation and the non-recommendation of high-concentration devices. Use when the user asks for the academic basis of the safety guidance.
