Available tools 6

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?".

水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) — questions

Answers built from our own checks of this server.

What can 水素分子医学文献データベース — Molecular hydrogen medical literature (H2 Papers) do?
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 214 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 in the form 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 214 ms on average, which is faster than 67% 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 49 times in the last week. Week over week that is +17%. 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?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at h2-papers.org, which runs on its operator's own terms.
