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

breakthrough
get_breakthrough
Everything Frontier holds on one entry: the plain-language summary, why it matters and what to watch, authors and institutions, the full Frontier Score breakdown (each pillar and what drives it, recency and confidence) and the sources behind each figure. Accepts an OpenAlex work id (e.g. W7214802080), an entry slug, or a frontierresearch.co entry URL.
breakthroughs
search_breakthroughs
Search Frontier's evidence-scored index of new research from the top scientific journals. Matches the query against titles, plain-language summaries, authors and topics, optionally within one field, and returns the matching entries ranked by Frontier Score (or newest paper first), each with its summary, score, Frontier URL and DOI. Leave the query empty to browse a field.
explain
explain_frontier_score
The Frontier Score method: its three pillars and what each measures, recency, the integrity rule, tiers and confidence.
fields
list_fields
The research fields Frontier covers, with how many entries each holds and its median Frontier Score.
latest
latest_breakthroughs
What Frontier added most recently: the entries listed in the last N days (the index adds a few new papers from the top journals every day), newest first, optionally within one field.

Frontier: evidence-scored science breakthroughs — questions

Answers built from our own checks of this server.

What can Frontier: evidence-scored science breakthroughs do?
It exposes 5 tools, read directly from the server on our last check. Among them: explain_frontier_score, get_breakthrough, latest_breakthroughs, list_fields, search_breakthroughs. 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 Frontier: evidence-scored science breakthroughs working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 112 ms. The bar chart above shows every period we have measured.
The registry lists Frontier: evidence-scored science breakthroughs as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Frontier: evidence-scored science breakthroughs?
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 Frontier: evidence-scored science breakthroughs need an API key?
No. Frontier: evidence-scored science breakthroughs completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
