## 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**: 0/100
  - Malware scan not yet available for this package.
  - CVE data not yet available for this package.
  - Install-script risk not yet assessed.
  - Dependency-health data not yet available.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (AGPL-3.0).
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 268 tokens (~89/item across 3 items; 1 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.

**Unverified: 2 categories.** Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-07-29 (score 11)

First indexed and scored.

## MCP tools (1)

### `scan` (~227 tokens)

Score a repository's engineering-trust signals (tests, secrets, isolation, claim-vs-reality, CI discipline) with the @cejel/cejel trust-certificate scan — the exact same offline, deterministic scoring as running the @cejel/cejel CLI on the path. Returns the trust cert as JSON: overall + code/process sub-scores (0-4) for a scored repository, or null scores with an abstention reason when Cejel establishes structural source absence or zero measurable free-core criteria; plus the verdict and top findings. No network, no telemetry, no signup. After a scan, the full HTML certificate and SVG badge are readable as the resources cejel-cejel://last-scan/certificate.html and cejel-cejel://last-scan/badge.svg.

Input parameters:

- `format` (string): summary (default): compact cert digest — scores, verdict, top findings. json: the full structured report, identical to the CLI's report.json.
- `path` (string, required): Path to the repository to score (absolute, or relative to the server CWD)
