## Quality 88/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 636 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 2, about 636 tokens to load them all
- tool set hash: 32ed12af301ef3cfdc30c85d5d52d767
- tools last changed: 2026-09-28T01:50:20.014Z
- badge: [![protogrid quality](https://protogrid.dev/badge/news.prh/revenue-agent.svg)](https://protogrid.dev/servers/news.prh/revenue-agent)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-28 `compare_openapi` changed (description)
  - before: Validates explicit before and after public OpenAPI/Swagger URLs and returns purchase terms for an immediate deterministic semantic comparison. 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.
  - after: 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.
- 2026-09-28 `check_openapi` changed (description)
  - before: 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 and requiredness changes as breaking, potentially breaking, non-breaking or informational, plus a Markdown summary. 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.

- 2026-09-27 `check_openapi` changed (description, outputSchema)
  - before: Audit a public OpenAPI/Swagger spec (JSON or YAML) for API contract changes: breaking-change detection, API drift detection and semantic specification comparison, suitable for ongoing spec monitoring. The paid analysis compares the spec with the service's last stored snapshot of that URL (the first check records the baseline) and returns a deterministic JSON report, classifying changes to endpoints, methods, request/response fields, types and required/optional status as breaking, potentially breaking, non-breaking or informational, plus a Markdown summary.
