Nothing serious here today

Today is the operative word: we check Hydrogen Studies every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

aggregate

aggregate_studies

Count matching studies grouped by year, subject, design, delivery_method, outcome, country, condition or species — for trends and 'how many' questions. Unknown values are counted separately.

compare

compare_evidence

Side-by-side evidence profiles for 2–4 groups of studies, e.g. inhalation vs drinking water for one condition, or two conditions. Each group is a set of filters merged over the optional shared filters.

condition

get_condition_evidence

Evidence profile for a health condition hub: how many studies, human vs animal vs in-vitro, number of human RCTs and participants, outcome mix, delivery methods, publication years, data coverage, and the strongest studies.

conditions

list_conditions

Every health condition hub with its study count, evidence grade (where reviewed) and page URL. Use the slug as the `condition` filter.

database

get_database_stats

Size and makeup of the database: total studies, breakdown by subject and design, year range, and field coverage.

find_related_studies

Studies a given study cites, studies that cite it, and the most similar studies by shared health conditions.

studies

search_studies

Find molecular hydrogen studies by keywords and/or filters. Returns compact study records (design, subject, sample size, delivery method, outcome, key finding, url). Sorted by relevance when a query is given, otherwise by strength of evidence.

study

get_study

Full record for one study: citation, design, population, H2 protocol (delivery, concentration, dosage), outcome, our plain-language summary and key finding, limitations, quality score with red flags, conditions/mechanisms, and links. Accepts an id, slug, DOI or study URL.

Hydrogen Studies — questions

Answers built from our own checks of this server.

What can Hydrogen Studies do?

It exposes 8 tools, read directly from the server on our last check. Among them: aggregate_studies, compare_evidence, find_related_studies, get_condition_evidence, get_database_stats, get_study and 2 more. 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 Hydrogen Studies working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 275 ms. The bar chart above shows every period we have measured.

How do I connect Hydrogen Studies?

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 Hydrogen Studies need an API key?

No. Hydrogen Studies completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Hydrogen Studies?

It answers our handshake in 275 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
