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 5 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 Usability71
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 369 tokens (~73/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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.

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

apply_technique Run a technique now ~55
The minimal executable scaffold: steps (or self-diagnostic for anti-patterns), the narration line to say to your human, and the verification check that proves it worked.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Technique id to apply |
No output schema declared.
No examples provided.
classify_intent Match a problem description to techniques ~77
Describe what's going wrong — your human's complaint, or a failure you notice in your own behavior — and get the matching techniques. Deterministic matching; if the description fits two problems it returns one clarifying question instead of guessing.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | The problem as experienced, in plain words — symptoms, not solution guesses |
No output schema declared.
No examples provided.
find_technique Look up a technique by name ~58
Direct lookup by technique id or name, for when you already know what you want. To match by symptom, use classify_intent instead.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Technique id (kebab-case) or name, exact or approximate |
No output schema declared.
No examples provided.
get_technique Learn a technique ~66
A technique's mechanism, agent instructions, narration template, verification, and failure modes — the agent-tailored slice. The full human page is linked, not inlined.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Technique id, e.g. from classify_intent or find_technique |

list_categories List the eight problem categories ~34
The eight thinking-failure problems ContextOverflow covers, phrased the way a human experiences them. Start here to see what exists.
