## 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 2026-11-05.

- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 0 of 46 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to QuincyGB/list-smith-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 368 tokens (~184/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**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `list_grade` (~145 tokens)

Grade one x402 route's Bazaar discovery metadata.

Calls ListSmith POST /v1/grade ($0.10 USDC on Base via x402).
Returns SDK validation verdicts, a schema-quality score, itemized
defects with severities, and a 0-100 grade. Diagnosis only — no
repaired content. Use list_fix when you want the repair.

Args:
    resource_url: Full URL of the x402 resource to grade.
    sample_output: Optional real response body from the endpoint;
        when supplied, it is also checked against the endpoint's
        published output schema.

Input parameters:

- `resource_url` (string, required)
- `sample_output`

### `list_fix` (~223 tokens)

Repair one x402 route's Bazaar discovery metadata.

Calls ListSmith POST /v1/fix ($0.50 USDC on Base via x402).
Returns a complete repaired discovery package — a full output
schema inferred from your sample, a sub-500-char description with
a use-when sentence, OpenAPI and well-known snippets, and paste-in
instructions. The package ships only if it passes both x402 SDK
validators.

Args:
    resource_url: Full URL of the x402 resource to repair.
    sample_output: One real response body from the endpoint
        (required). The repaired output schema is inferred from
        this sample only — nothing is invented.
    name: Optional display name for the generated description;
        derived from the URL when omitted.
    category: Optional category (e.g. token-risk, search, data,
        media, monitoring) used to phrase the description's
        use-when sentence.

Input parameters:

- `category`
- `name`
- `resource_url` (string, required)
- `sample_output` (required)
