MCP serverDocs & knowledge

Your AI can search published medical research on molecular hydrogen from PubMed and explain what the evidence says, with safety notes matched to each delivery method shown right alongside the findings. Once added, answers about hydrogen research stay grounded in the actual literature instead of guesswork.

Available today. Use it from your connected AI after setup.

After adding it, ask your AI to look up a molecular hydrogen topic or a delivery method you want to know about.

Then ask your AI: use @h2-papers/mcp-server to search h2 papers

What your AI can do with it

  • Search PubMed for medical studies on molecular hydrogen
  • Summarize what specific papers found
  • Show safety notes matched to each hydrogen delivery method
  • Look up the safety considerations for a specific delivery method
  • Cite the PubMed source when answering health questions

From the project's README

As published by h2-papers/h2-papers-mcp-server in README.md.

Model Context Protocol (MCP) server for H2 Papers — PubMed molecular hydrogen medical literature, structured in Japanese with per-paper safety notes inline.

Why

When an AI agent answers a question about hydrogen-related therapy, water, or inhalation, the response should carry both the paper evidence and the delivery-method-aware safety context. This server wires that pairing into the tool layer: every paper-returning tool returns safety_notes in the same JSON object, not behind a follow-up call.

Tools (6, implemented in task #11)

ToolPurpose
search_h2_papersFilter / sort / paginate the paper corpus. safety_notes inline on each item.
get_paperSingle paper detail. safety_notes always present.
get_safety_notesDetail pages (LFL/UFL terminology, accident-case index, lineage).
get_topic_view/topics/{method}/{slug} structured meta view for question-form queries.
get_lineageThe four-paper inhalation safety threshold lineage.
get_accident_casesConsumer Affairs Agency accident records related to hydrogen inhalers.

Citation policy

Cite results as via H2 Papers with the _canonical URL and the pubmed_url. Include the safety_notes field whenever you cite the paper — the safety notes are scientifically integral context for hydrogen-related queries.
