Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 53 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name release-radar-mcp.

  • Pass
    Lists tools

    tools/list returned 5 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 53 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 53 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

    16 of 16 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 2026-11-10T23:33:34.517021Z, within 180 days.

Capabilities

Tools 5

release_radar_github_latest_deploy

Low-level building block: the latest GitHub deployment for a repo (falls back to the latest release), returning sha + timestamp. Used internally by release_radar_whats_broken_since_last_deploy. GitHub: GET /repos/{owner}/{repo}/deployments.

Discovered
release_radar_incident_snapshot

COMPOSITE. A right-now on-call picture: top unresolved Sentry issues + active (triggered/acknowledged) PagerDuty incidents + who's currently on-call, fused into one snapshot with a human summary. Each service degrades independently if its creds are missing.

Discovered
release_radar_oncall_handoff

COMPOSITE. A start-of-shift briefing for whoever is currently on call, fusing all three services: (a) PagerDuty current on-call + any active (triggered/acknowledged) incidents they're inheriting, (b) the GitHub deployment/release that most recently shipped (what's live), and (c) Sentry's top unresolved errors. Correlates them into one object — including a heads-up when a fresh deploy coincides with active incidents (a likely culprit). Degrades gracefully: every service is optional; whatever's unconfigured or failing is named in `notes` and the briefing still returns. Never crashes.

Discovered
release_radar_sentry_recent_issues

Low-level building block: unresolved Sentry issues over a relative window. Sentry: GET /api/0/projects/{org}/{project}/issues/?query=is:unresolved.

Discovered
release_radar_whats_broken_since_last_deploy

COMPOSITE. Finds the latest GitHub deployment/release for a repo, then queries Sentry for unresolved issues SINCE that deploy's timestamp (the deploy time drives the Sentry window), then looks up who's currently on-call in PagerDuty — and synthesizes one situational-awareness object. Degrades gracefully: if Sentry or PagerDuty creds are absent it returns what it can plus a note. GitHub is required (it's the anchor).
