- 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.secret_in_url`: no templated URL

### tool hygiene: 93 (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`: 11 of 11 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 1 of 11 tools declare all four hints; missing: find_stations (destructiveHint, idempotentHint); currents (destructiveHint, idempotentHint); marine_warnings (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 1,949 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 2 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: 11, about 1,949 tokens to load them all

## Tools (11)

- `best_low_tides`: The lowest daylight low tides over the next days (default 30, up to 90 with a pass key), marking the good ones for clamming, foraging and tide pools.
- `coast_map_pass`: What the Coast Map Pass adds over the free map (offline regions for trips with no signal; longer tide and current ranges for assistants), its prices (CA$5 a month or CA$55 a year), whether it is on sale yet, and the purchase or support links. Covers offline use, longer tide ranges and upgrading.
- `currents`: Slack water and maximum flood/ebb times and speeds at a current station, in local time. Up to 7 days free; longer with a Coast Map Pass key.
- `find_stations`: Nearest tide stations (high/low times) and current stations (slack water, max flood/ebb) to a point, with distance and time zone. Coverage: Canada, the US, Norway, Ireland, the Netherlands, New Zealand, Australia (Queensland) and modelled tides elsewhere.
- `marine_forecast`: Hourly wind and gusts (knots), direction, temperature, rain, fog and thunder risk for the next 48 hours, plus wave height and period, from Environment Canada (HRDPS/GDWPS), the US National Weather Service or MET Norway.
- `marine_warnings`: Marine warnings (gale, storm, small craft…) in effect for the marine forecast area at a point.
- `pass_status`: Checks whether the payment for a purchase reference has completed. Returns pending (with a retry interval) or paid with the pass key, which is sent as "Authorization: Bearer <key>" from then on, plus a link that activates the pass in the user's own map.
- `plan_paddle`: One call that answers "what will the water be like at this spot?": the nearest tide station with 2 days of highs and lows, currents nearby, the next 24 h of wind, gusts and waves with the maxima, warnings in effect, water temperature and sunrise/sunset, with the important heads_up lines listed first.
- `start_pass_purchase`: Begin a Coast Map Pass purchase without leaving the conversation: returns checkout links (CA$5 a month or CA$55 a year, Stripe, no account) tagged with a purchase reference, or says the pass is not on sale yet. The user pays in their browser; the reference identifies that payment afterwards.
- `tide_times`: High and low tides with heights, in the station's local time. Up to 7 days ahead free; longer ranges (up to 90 days) need the user's Coast Map Pass key.
- `water_temperature`: Water temperature from the nearest buoy within 40 km, otherwise satellite sea surface temperature.
