## Trust

- hygiene: 100
- liveness: 100
- freshness: 45
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% -stale-184d
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: linkpulse_diff (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); linkpulse_resolve (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); linkpulse_check (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 378 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`: no 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: 4, about 378 tokens to load them all
- tool set hash: 60f7ea10195a8829e6350c6823b400aa
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.walkojas-boop/linkpulse.svg)](https://protogrid.dev/servers/io.github.walkojas-boop/linkpulse)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `linkpulse_check`: Fetch a URL and return its current state: HTTP status, final URL after redirects, SHA-256 content hash, classification, readability score, title/meta-description, and wayback archive fallback if dead. Cached 10 minutes.
- `linkpulse_classify`: Classify content you already have (status code + content-type + body sample) without an outbound fetch. Useful if your agent already fetched the URL via another tool.
- `linkpulse_diff`: Re-check a URL and tell you whether its content hash has changed since a previous hash you supply. Returns boolean + new hash.
- `linkpulse_resolve`: Resolve redirect chain for a URL without downloading the full body. Returns final URL + redirect count.
