## Trust

- hygiene: 80
- liveness: 98
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-95% +updated-5d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 100/100 (new)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 336 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 4 of the 7 days needed

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

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

- tools: 1, about 336 tokens to load them all
- tool set hash: deb6023f7e61b6ea29d6bc3c64c42432
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.workers.mike-tusa.hrefgate/hrefgate.svg)](https://protogrid.dev/servers/dev.workers.mike-tusa.hrefgate/hrefgate)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `lint_hreflang`: Lint hreflang annotations for international SEO. Accepts pasted text (not a URL; this tool never fetches anything): page HTML with <link rel="alternate" hreflang> tags, an XML sitemap with xhtml:link alternates, or a JSON set {"pages":[{"url","canonical","alternates":[{"hreflang","href"}]}]}. Checks language/script/region codes, x-default, self-reference, canonical conflicts, duplicates and reciprocal return links. Returns valid true/false, counts, the codes found, and up to 25 issues with paths, messages and suggested fixes. Read-only. Same engine as the HrefGate JSON API (POST /api/lint).
