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

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 650 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name releasealert.

  • Pass
    Lists tools

    tools/list returned 8 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 650 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 650 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

    19 of 19 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 2026-10-23T01:25:20.965126Z, within 180 days.

Capabilities

Tools 8

check_manifest

Check the dependencies a manifest or lockfile names, such as a package.json, go.mod, requirements.txt, or Cargo.lock. For each one, it reports how the version asked for compares with the latest release, and the advisories that affect that version, with the versions that fix them. A range is checked at the version it names, as ^1.2.0 is at 1.2.0. Dependencies that couldn't be checked are listed under skipped, with the reason. A project new to Release Alert is added; until it has been checked, releases_checked or advisories_checked is false, and checking again in a few minutes fills in the rest.

Discovered
get_cve

Get a CVE by its id.

Discovered
get_project

Get a project by its registry and name.

Discovered
list_project_cves

List the CVEs that affect a project, newest first.

Discovered
list_project_release_notes

List the release notes of every release of a project after one version and up to another, newest first. A release without notes is still listed, with notes null and a link to the release. Pre-releases are left out unless the last version is one.

Discovered
list_project_releases

List a project's releases, newest first.

Discovered
list_registries

List the registries Release Alert tracks. A registry's id is what search and the project tools take.

Discovered
search

Search for a project by its name, optionally followed by a version, or by its URL, or for a CVE by its id. Each project found carries the registry and name the project tools take.
