## Quality 88/100 (new)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 88 (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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_recent_stockings (idempotentHint); search_waters (idempotentHint); get_water (idempotentHint)
- pass `tools.token_cost`: about 456 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: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 1 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: 3, about 456 tokens to load them all
- tool set hash: 1556026282574c6ae1a82783f8e7f012
- tools last changed: 2026-11-13T21:45:41.892Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.castthewater/cast-the-water.svg)](https://protogrid.dev/servers/com.castthewater/cast-the-water)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-11-13 `get_waterbody` removed
  - Full water body detail for a state open for indexing: identity, size/shoreline, structured nearest_town + nearest_town_label, stocking, natural species, surveys, editorial content (incl. gauge_relationship / gauge_notes), gallery, regs link, gauge. Pass id or seo_path (state/county/slug). A closed state is not available. Admin listing/writes are HTTP/Central only.
- 2026-11-13 `find_nearby` removed
  - Find water bodies near a lat/lon in states open for indexing. At most 25 hits from a bbox query. Filters: radius, species, min acres, stocked-only, recent stocking window, optional amenity feature flag.
- 2026-11-13 `search_places` removed
  - Search US census places (cities/towns) by name in states open for indexing. Use the lat/lon of a hit with find_nearby.
- 2026-11-13 `get_nearby_waterbodies` removed
  - Nearby water bodies in states open for indexing, for internal linking / trip planning. A closed state is not available.
- 2026-11-13 `get_species` removed
  - Likely natural species (USGS GAP HUC8) and survey abundance rows for a water body in a state open for indexing. A closed state is not available.
- 2026-11-13 `get_stocking_history` removed
  - Stocking events for a water body in a state open for indexing. Year-only dates are 'sometime in YYYY' with estimated true. An around date stays an estimate.
- 2026-11-13 `get_conditions` removed
  - Conditions for a water in a state open for indexing. Reads the existing forecast and USGS cache only: a miss is unavailable, with the canonical page URL. No live fetch.
- 2026-11-13 `search_waterbodies` removed
  - Search water bodies by name (or nearest town name). Optional state filter. Only states open for indexing are returned. Prefer this over county browse.
