Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1226 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-03-26, serverInfo.name cerebrum.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Fail
    Current protocol

    Negotiated 2025-03-26. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1226 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1226 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

    4 of 4 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.

  • Pass
    Source repo linked

    A 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 2026-10-14T13:34:31.917947Z, within 180 days.

Capabilities

Tools 4

get_reception_report

Build the standing reception report for one paper: the citation statement counts Cerebrum holds for it, the reception tallies served via scite.ai, and its retraction status under the multi signal rule, where a paper counts as retracted only when at least two of the three checking channels agree. A clean read prints no retraction line at all, and a status no channel could settle is reported as unknown.

Discovered
get_statements

Look up what later papers say about a paper, in the citing sentences Cerebrum has collected and classified for it. Returns, for each DOI, whether its sentences are ready, still being collected, or settled empty, the counts by stance, and the sentences themselves, each with two separate labels: the stance Cerebrum assigned and the purpose Semantic Scholar recorded. A paper still being collected is reported as collecting, never as holding nothing.

Discovered
get_trending

Get the current Today in Science edition and return the top headlines grouped by section with links to the original stories.

Discovered
search_literature

Search the scientific literature for a research question and return a cited answer with a numbered source list. Use this when you need evidence from papers rather than general knowledge.
