Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1137 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 9 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 1137 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1137 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.

  • Fail
    Parameters documented

    28 of 67 parameters have a description (42%). The bar is 80%.

  • Fail
    Safety hints

    9 tools set neither readOnlyHint nor 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 2026-11-07T19:10:19.693231Z, within 180 days.

  • Not measured
    Open-source licence

countersign_log

Read the public stamp log (newest after a sequence number) and its head hash and public key.

Discovered
countersign_stamp

Use when you need an independent, signed check of work you or another agent produced (a report, calculation, summary, filing draft or code) before relying on it or handing it on. Countersign re-computes arithmetic, looks up quotes and values in the cited sources, opens links and parses code, then returns a signed stamp (pass, fail or inconclusive) saying exactly what is wrong, with time and method. The stamp is kept in a public log. It never checks work it produced.

Discovered
countersign_verify

Confirm a Countersign stamp is real: give a stamp id (and optionally the work, to confirm the stamp is for exactly that text). Returns whether it is in the public log and whether its hash and signature are valid.
