Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
accident
get_accident_cases
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.
lineage
get_lineage
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.
paper
get_paper
Fetch a single paper by PMID. Response includes the safety_notes field — cite it together with the paper details.
papers
search_h2_papers
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.
safety
get_safety_notes
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).
topic
get_topic_view
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?".

It exposes 6 tools, read directly from the server on our last check. Among them: get_accident_cases, get_lineage, get_paper, get_safety_notes, get_topic_view, search_h2_papers. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 212 ms. The bar chart above shows every period we have measured.
How do I connect 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers)?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) need an API key?
No. 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers)?
It answers our handshake in 212 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers)?
The npm package @h2-papers/mcp-server was installed 22 times in the last week. Week over week that is +29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
