## Quality 72/100 (needs work)

### 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
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 17 of 18 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 17 of 18 tools declare all four hints; missing: domain_dns_tls_audit (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 5,090 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 38 tool changes in 30 days
- fail `stability.rug_pull`: 19 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

### Tool changes

- 2026-10-20 `web_monitor` changed (description, inputSchema) **meaning changed**
  - before: Compare an HTTPS page or Serper search snapshot by SHA-256. Optional DeepSeek structured diagnostic. Separate authenticated Agent Tools relay: requires your own company Bearer API key. URL and query are mutually exclusive. Prepaid uses the shared company credit wallet; x402 produces a workload-specific payment quote. Preserve the same idempotency key, arguments and payment mode on retry; admission is not delivery. Poll job status and fetch result with SHA256 verification.
  - after: Fetch a public HTTPS page and report its content hash, with an optional change comparison. Separate authenticated processing relay: requires your Agent Tools Bearer API key and an available catalog operation. Default x402 returns a workload quote; prepaid spends shared company credits. Use the same idempotency_key and inputs on retries. An admitted job is not delivered; poll skavio_agent_job_status then skavio_agent_job_result and verify SHA256. No execution when backend admission is disabled.
- 2026-10-20 `web_extract` changed (description, inputSchema) **meaning changed**
  - before: Extract one public HTTPS page or search Google then extract 1–5 actual source pages. Optional DeepSeek structured diagnostic. Separate authenticated Agent Tools relay: requires your own company Bearer API key. URL and query are mutually exclusive.

  - after: Fetch a public HTTPS page and return only its visible text. Separate authenticated processing relay: requires your Agent Tools Bearer API key and an available catalog operation. Default x402 returns a workload quote; prepaid spends shared company credits. Use the same idempotency_key and inputs on retries. An admitted job is not delivered; poll skavio_agent_job_status then skavio_agent_job_result and verify SHA256. No execution when backend admission is disabled.
