Nothing serious here today

Today is the operative word: we check Arca Life Sciences 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 4

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

datasets

list_datasets

Describe the corpus this server searches: the source lanes search_medical accepts in sourceTypes, with the underlying mirrored datasets in each.

medical

search_medical

Hybrid keyword + semantic search over Arca's mirrored public-source corpus: FDA drug labels, Drugs@FDA approvals, complete response letters, warning letters, Orange Book, Purple Book, NDC, drug shortages, device 510(k)/PMA/registrations, MAUDE adverse events, DailyMed, GUDID, postmarket requirements, import refusals, inspections, Form 483s, ClinicalTrials.gov studies, VAERS reports, CDC data, EU expert panel opinions, and BfArM/PMDA device vigilance. Read-only lookup of already-published records: it cannot file, submit, or report anything to FDA, VAERS, MedWatch, or any other agency, so do not call it for requests to file or submit a report. When the question names a record type (warning letters, labels, adverse event reports, trials, recalls), pass the matching sourceTypes rather than searching the whole corpus. Results carry recordId for fetch_source_record and a citable source URL.

papers

search_papers

Ranked PubMed literature search: Arca's paper index fused with PubMed Best Match, with citation and open-access metadata from OpenAlex. Returns papers with title, authors, journal, year, DOI, PMID, abstract, citation count, and open-access status.

source

fetch_source_record

Read the full indexed text of one record from the public-source corpus by its recordId (returned by search_medical). Use after search when the excerpt is not enough.

Arca Life Sciences — questions

Answers built from our own checks of this server.

What can Arca Life Sciences do?

It exposes 4 tools, read directly from the server on our last check. Among them: fetch_source_record, list_datasets, search_medical, search_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 Arca Life Sciences 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 459 ms. The bar chart above shows every period we have measured.

How do I connect Arca Life Sciences?

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 Arca Life Sciences need an API key?

No. Arca Life Sciences completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Arca Life Sciences?

It answers our handshake in 459 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
