## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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: get_rules (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_site (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_log_summary (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 604 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: 6, about 604 tokens to load them all
- tool set hash: ceb839bb7eda54eaeccd8211f44c7d6c
- badge: [![protogrid quality](https://protogrid.dev/badge/app.rowb.pool-log/water-log.svg)](https://protogrid.dev/servers/app.rowb.pool-log/water-log)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `add_readings`: Append water readings to an existing log. Requires a bearer key.
- `check_readings`: Check a list of pool or spa water readings for things that cannot be true, and compare pH, free chlorine and bromine against the ranges published on the US CDC pages. Deterministic arithmetic only - no AI. It does not decide whether a pool is legally compliant, and it does not know your local code.
- `create_site`: Open a water-test log for one pool, hot tub or splash pad (returns a site id). Requires a bearer key.
- `get_log_summary`: Every reading, the flagged issues, the CDC-range counts, the longest gap between tests, and the A4 log sheet URL, for one log. Requires a bearer key.
- `get_rules`: The exact rule table this service checks against, the quoted source of every range, and what it explicitly does not claim. Quote it if you need to explain a result.
- `request_operator_signoff`: Create a one-time URL the pool operator can open to confirm the log. Requires a bearer key. The token is single use.
