## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 45
- drivers: +website +reachable +uptime-99% +updated-24d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 84/100 (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: 100 (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`: 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 365 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 67 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 2, about 365 tokens to load them all
- tool set hash: 9832d6c57a3ebadd2a16e3e681779a8f
- tools last changed: 2026-10-24T21:56:37.461Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.hal-boring-utils/expiry-watch.svg)](https://protogrid.dev/servers/io.github.hal-boring-utils/expiry-watch)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-24 `check_domain_expiry` changed (description)
  - before: Looks up when a domain registration expires, over RDAP at the registry for its TLD. Subdomains are looked up by their registered domain (www.example.co.uk becomes example.co.uk).
  - after: Looks up a domain registration over RDAP at the registry for its TLD: when it expires, the registrar, the statuses (flagging a hold, redemption, pending delete or pending transfer) and the nameservers. Subdomains are looked up by their registered domain (www.example.co.uk becomes example.co.uk).
- 2026-10-24 `check_certificate` changed (description) **meaning changed**
  - before: Connects to a domain on port 443 and reports its TLS certificate: whether it is trusted and matches the name, the issuer, the expiry date and days left, the lifetime, the chain and the TLS version.
  - after: Connects to a domain on port 443 and reports its TLS certificate: whether it is trusted and matches the name, the issuer, the expiry date and days left, the lifetime, the chain and the TLS version, what each of its server addresses serves (up to 4 IPv4 and 4 IPv6), and, for certificates from Let’s Encrypt, Google Trust Services, ZeroSSL or Sectigo, the renewal window the CA suggests (ACME Renewal Information).
