- 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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_stations (destructiveHint); get_tides (destructiveHint); get_conditions (destructiveHint)
- pass `tools.token_cost`: about 556 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: 3, about 556 tokens to load them all

## Tools (3)

- `get_conditions`: Current wind speed and direction, sea surface temperature and sky at a tide station. Any of them may be missing where the forecast service has no data.
- `get_tides`: High and low tide times and heights for one station, over one or more days in the station's local time, plus the current height and direction when the range includes now. Times are ISO 8601 with the station's UTC offset. Heights are above the station's chart datum, in feet for US stations and metres for Canadian ones unless units is given.
- `search_stations`: Find tide stations in the United States, Canada and US territories by place name, by position, or both. With a name, results are ranked by how well they match (then by distance, if a position is given). With only a position, the nearest stations come first. Returns each station's id, which get_tides and get_conditions take.
