## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 19/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 0 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 452 tokens (~226/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `pre_flight_check` (~242 tokens)

Security pre-flight check for local file changes BEFORE committing. Run this whenever you are about to suggest `git commit`, `git push`, or open a pull request — especially when changes add package imports or dependencies (package.json / requirements.txt / Cargo.toml / go.mod / Gemfile / composer.json / import statements) or could contain secrets. Detects AI-hallucinated (non-existent) packages by live-checking six registries (npm, PyPI, crates.io, RubyGems, Go module proxy, Packagist) plus a bundled public threat-feed snapshot, which keeps catching a known hallucinated name even after an attacker registers it; risk-scores dependencies an AI agent introduced by compounding metadata signals (new + install-scripts + low-adoption + no-provenance = an attack shape no single check flags); and finds hardcoded credentials via pattern + entropy analysis. Always free, no account required. Returns CLEAR, REVIEW_REQUIRED, or BLOCKED with specific findings and remediation.

Input parameters:

- `context` (string): What these changes do (helps triage)
- `files` (array, required): Files staged for commit (path + content)

### `report_hallucination` (~210 tokens)

Report an AI-hallucinated package name to Graneth's public threat feed, so every user's pre-flight catches it — permanently, even if an attacker registers the name later. IMPORTANT: only call this AFTER the human has explicitly agreed to report the name; ask them first. Sends exactly one package name + ecosystem to graneth.com (never file contents). The server re-verifies non-existence against the live registry before accepting. Reportable ecosystems: npm (unscoped), pypi, crates, gems — namespaced names (npm @scope, go, composer) are rejected to keep internal package names out of a public feed. Optional `reporter` is a public attribution handle shown on the feed entry.

Input parameters:

- `ecosystem` (string, required): Registry the name was checked against
- `package` (string, required): The hallucinated package name (as caught by pre_flight_check)
- `reporter` (string): Optional public attribution handle ([a-zA-Z0-9_-])
