MCP Registry Validator — Check Endpoints Actually Resolve
REMOTE · MCP-UPTIME.THEOPSLOG.WORKERS.DEV · SCANNED AUG 3
Check an MCP endpoint resolves: liveness, live tool list, schema drift. Free.
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 Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 311 tokens (~77/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 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

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 3 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.
- 2 Aug 26 0

First indexed and scored.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

check_mcp_endpoint ~89
Probe an MCP endpoint right now: is it alive, which transport it speaks, how many tools it exposes, and whether its tool schema changed since the last check. Use before depending on a third-party MCP server.
| Name | Type | Req | Description |
|---|---|---|---|
| include_tools | boolean | — | Return the full tool list, not just the count. |
| url | string | yes | Public http(s) URL of the MCP endpoint to inspect. |
No output schema declared.
No examples provided.
check_schema_drift ~70
Probe an MCP endpoint and diff its tool schema against the last stored snapshot: tools added, removed, or whose description/inputSchema changed. Schema drift fails quietly mid-run, which is why it is worth checking.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Public http(s) URL of the MCP endpoint to inspect. |
No output schema declared.
No examples provided.
get_known_tools ~55
The tool list last observed at an MCP endpoint, with the timestamp of the most recent schema change. Reads stored history; does not probe.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Public http(s) URL of the MCP endpoint to inspect. |
No output schema declared.
No examples provided.
get_uptime ~70
Uptime history for an MCP endpoint over the last N days (max 30), with incident windows. Reads stored history; does not probe.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | — | Window in days. Default 30. |
| url | string | yes | Public http(s) URL of the MCP endpoint to inspect. |
No output schema declared.
