- Look up a chemical compound by name or molecular formula. Returns name, formula, and source from offline and online databases.GPL 3.0
- Computes the natural isotopic pattern (isotopologue masses, m/z, and relative intensities) of a chemical formula for mass spectrometry analysis, using NIST atomic weights and isotopic compositions.GPL 3.0
- Report the availability, version, and environment details of the MCP server.GPL 3.0
- 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.ConnectorNo auth
- Returns Consumer Affairs Agency (Japan) accident records related to hydrogen inhalers and the editorial framing. Use when the user asks about real-world safety incidents.ConnectorNo auth

PubMed molecular-hydrogen medical literature with delivery-aware safety notes inline.
Chemical molecular intelligence platform covering compound search, structure analysis, physicochemical property retrieval, and molecular interaction profiling.
- 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).ConnectorNo auth
- 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?".ConnectorNo auth
- Fetch a single paper by PMID. Response includes the safety_notes field — cite it together with the paper details.ConnectorNo auth
- 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.ConnectorNo auth
