Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 362 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name arca-life-sciences.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 362 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 362 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    15 of 15 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-06T05:02:17.946764Z, within 180 days.

Capabilities

Tools 4

fetch_source_record

Read the indexed text of one public-source record by its recordId (returned by search_medical). Use after search when the excerpt is not enough. Returns a bounded text window; pass nextInput unchanged to continue. contentCapped reports text unavailable beyond the stored content.

Discovered
list_datasets

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

Discovered
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. Press releases and SEC company filings are searched only when sourceTypes names press_releases or company_filings. 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.

Discovered
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.
