Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security86
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to j0hanz/cortex-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 149 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability73
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 652 tokens (~93/item across 7 items; 1 tools + 6 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

- 3 Aug 26 +1
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.

reasoning_think Reasoning Think ~496
Structured multi-step reasoning tool. Decomposes analysis into sequential thought steps stored in a persistent session trace. USAGE PATTERN: 1. Start: { query: "...", level: "basic"|"normal"|"high"|"expert", thought: "your analysis..." } 2. Continue: { sessionId: "<from response>", thought: "next step..." } — level is optional; session level is used 3. Repeat until status: "completed" — the summary field contains the exact next call to make IMPORTANT: Pass the returned sessionId on every continuation call. The thought parameter stores YOUR reasoning verbatim — write thorough analysis in each step. Use stepSummary for a 1-sentence conclusion per step — these accumulate in the summary field for navigation. Levels: basic (1–3 steps, 2K budget), normal (4–8 steps, 8K budget), high (10–15 steps, 32K budget), expert (20–25 steps, 128K budget). Alternatives: runMode="run_to_completion" (batch, basic level only), or observation/hypothesis/evaluation fields (structured). Errors: E_SESSION_NOT_FOUND (expired — start new), E_INVALID_THOUGHT_COUNT (check level ranges).
