## 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**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (132 of 136), 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 (132 of 136), so this covers what we could see, not the whole tree.
- **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 (MIT).
  - Actively maintained (last published 100 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 42/100
  - 0% 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 423 tokens (~60/item across 7 items; 6 tools + 1 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: 1 category.** A category scored 0 because we could not verify it: 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.

First indexed and scored.

## MCP tools (6)

### `validate_output` (~74 tokens)

Score agent output quality against configurable criteria. Checks length, required keywords, forbidden patterns, claim density, and task relevance.

Input parameters:

- `criteria` (object, required): Quality criteria to check against
- `output` (string, required): The agent output text to validate
- `task_description` (string, required): Description of what the agent was asked to do

### `check_hallucination_risk` (~101 tokens)

Estimate hallucination likelihood in agent output. If source text is provided, checks grounding. Otherwise flags outputs with high counts of specific numbers, dates, and URLs.

Input parameters:

- `claim_count` (number): Threshold for number of specific claims before flagging as high risk (default 5)
- `output` (string, required): The agent output text to analyze
- `source_text` (string): Original source material the output should be grounded in (optional)

### `check_scope_compliance` (~60 tokens)

Validate that agent output stays within a defined scope contract. Checks allowed/forbidden topics, word limits, and required sections.

Input parameters:

- `output` (string, required): The agent output text to check
- `scope` (object, required): Scope contract to validate against

### `log_validation` (~101 tokens)

Store a validation result for trending and failure pattern analysis. Accumulates per-agent statistics over time.

Input parameters:

- `agent_id` (string, required): Unique identifier for the agent whose output was validated
- `issues_count` (integer, required): Number of issues found
- `output_hash` (string, required): Hash or identifier for the specific output that was validated
- `pass` (boolean, required): Whether the output passed validation
- `score` (number, required): Quality score from 0-100

### `get_failure_patterns` (~47 tokens)

Analyze common failure modes for a specific agent. Returns pass rate, average score, most frequent issue types, and quality trend direction.

Input parameters:

- `agent_id` (string, required): Agent identifier to analyze

### `generate_quality_report` (~36 tokens)

Generate a quality dashboard for all validated agents. Shows per-agent summaries, overall pass rate, worst/best performers, and actionable recommendations.
