## Findings

- **info** The word "credentials" in `check_openapi` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.url.description mentions "credentials".

inputSchema.properties.url.description: "...ger JSON or YAML URL (http or https, no credentials or query string)"
```


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_openapi`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Developer tool for OpenAPI audit, API analysis, Swagger analysis, and API contract change validation (not general OpenAPI conformance linting). The paid analysis detects breaking changes and API drift by comparing a public OpenAPI/Swagger JSON or YAML contract with the service's last stored snapshot of that URL (the first check records the baseline). It returns deterministic JSON classifying endpoint, method, media-type, status, request/response field, type, requiredness, and structural oneOf/anyOf branch changes as breaking, potentially breaking, non-breaking or informational, plus a Markdown summary. It does not infer schema satisfiability or branch overlap; not and external references are unsupported. Cost: 0.10 USDC per completed analysis via x402 on Base (eip155:8453), settled only after the analysis is computed. This MCP tool itself is free: it validates the URL and returns the x402 endpoint and payment terms; it does not run the analysis or move funds. Canonical service OpenAPI: https://agent.prh.news/openapi.json. To get the analysis, POST {"url": "<spec URL>"} to the returned endpoint with an x402-capable HTTP client.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `compare_openapi`

- The name "compare_openapi" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validates explicit before and after public OpenAPI/Swagger URLs and returns purchase terms for an immediate deterministic semantic comparison, including structural oneOf/anyOf branch changes. It does not infer schema satisfiability or branch overlap; not and external references are unsupported. The paid endpoint returns breaking, potentially breaking, non-breaking and informational findings plus Markdown without reading or advancing snapshot history. Cost: 0.25 USDC via x402 on Base (eip155:8453). This MCP tool is free and never executes analysis or moves funds.
```
