Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security78
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1475 tokens (~122/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

healthchecksio_create_check Create check ~365
CREATES a new check — this MODIFIES live monitoring config. Provide a `timeout` (simple period-based check) OR a `schedule` + `tz` (cron-based check); the two are mutually exclusive.

| channels | string | — | Integrations to assign: "*" for all, or a comma-separated list of integration ids. |
| desc | string | — | Free-form description of the check. |
| grace | integer | — | Grace time in seconds after the deadline before the check goes down. |
| manual_resume | boolean | — | If true, a paused check does not auto-resume on the next ping (resume manually). |
| methods | string | — | Allowed ping HTTP methods: "" (any) or "POST" (POST-only). |
| name | string | — | Human-readable name for the check. |
| schedule | string | — | Cron expression for the expected ping schedule (e.g. "15 5 * * *"). Mutually exclusive with `timeout`; requires `tz`. |

| tags | string | — | Space-separated list of tags, e.g. "prod db backups". |
| timeout | integer | — | Expected period between pings, in seconds (60..31536000). Mutually exclusive with `schedule`. |
| tz | string | — | Server's timezone for the cron `schedule`, e.g. "Europe/Riga". |
