Common questions

Is Gillby safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 22 days ago, and the latest version (1.0.1) reached the registry 22 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Gillby MCP

Florida marine conditions for AI agents. Tides, waves, wind, marine forecasts, hazards, red tide, rip currents, depth-aware boat routing and 84 verified coastal spots, through one remote MCP server and a public HTTP API.

Connect any MCP-compatible agent (Claude, ChatGPT, Cursor, Windsurf, Claude Code) to Gillby, a guide to Florida water. Public data needs no API key, no login, no signup: point your agent at https://www.gillby.com/mcp and ask.

Why Gillby exists

I'm newer to boating. I'm not from Florida, but I've been down here for years. My wife said it first: it was way too hard to get a good read on the weather without checking five different things, and when we asked an AI, it didn't have good answers on its own.

So I built Gillby. It's a hobby and a passion project: one map and one clock for a day on Florida water, plus this MCP server so your assistant can answer from real water data instead of guessing. More in Why I built Gillby.

"Can I run Boca Inlet tomorrow morning?" · "Is the Gulf Stream close off Palm Beach?" · "Any red tide on the Gulf coast?" · "Will my 2.5 ft draft make it to the sandbar at low tide?"

What makes it different

One map, one clock. Wind, waves, tide, radar and lightning line up on the same timeline, per spot.
Chop for your boat. Ride comfort accounts for boat size and hull, so a 21-foot center console gets a different answer than a big sportfish.
Bridge clearance at today's tide. 97 bridges, with charted clearance adjusted for the NOAA tide prediction and the nearest live water-level gauge when it passes checks.
Calibrated rain and thunder chances. Probabilities are recalibrated against airport observations, so a stated chance matches how often it actually rains.
A 16-day outlook with honest confidence. Ensemble ranges and a trend against normal. From day 10 on, every day is labeled "Low confidence: trend only."
Sources stay attached. Every answer carries source names, observation times, freshness and anything unavailable.

Claude Code plugin

This repo is also a Claude Code plugin: the Gillby MCP server plus 9 skills and 6 agents.

/plugin marketplace add OneWave-AI/gillby-mcp

/plugin install gillby@gillby

On Claude Code 2.1.275+ this is one step: /plugin install gillby --marketplace OneWave-AI/gillby-mcp.

Agents and evals call tools as mcp__plugin_gillby_gillby__ . If you also connected Gillby as a claude.ai connector, the same tools appear twice; either works with the skills.

Skills	Use for
`gillby-conditions`	Live read at any spot, compare spots
`gillby-go-no-go`	Boating / fishing / inlet trip call with departure windows
`gillby-route`	Depth-, tide- and bridge-aware routing, ICW-only
`gillby-fishing`	Gulf Stream, temp breaks, color, reefs, wrecks, tides
`gillby-beach-day`	Swim, rip risk, bacteria, sargassum, jellyfish, UV
`gillby-dive`	Visibility, currents, dive sites, protected areas
`gillby-surf-kite`	Surf, SUP, kite (rider wind range), skim, paddle
`gillby-water-quality`	Red tide, algae, Lake O, discharges, fish kills
`gillby-account`	Saved places, trips, vessel, settings (OAuth)

Agents	Role
`gillby-captain`	Trip planner, go / caution / no-go
`gillby-navigator`	Charts, depth, bridges, grounding risk
`gillby-fishing-guide`	Offshore and inshore fishing conditions
`gillby-beach-scout`	Best beach for swim, surf, kite, snorkel
`gillby-surf-guide`	Surf session windows for Florida and supported California spots
`gillby-water-quality-analyst`	Dated water-quality records, explained

Evals

evals/ holds 6 cases (spot conditions, go/no-go, route asks for draft, kite asks for wind range, swim no-go with no wading, captain agent). MCP calls are answered by mocks recorded from the live server (evals/mocks/gillby/), so runs need no network access to Gillby.

Tools

105 tools on the hosted server, generated from the live tool reference. Start with list_spots and get_conditions with view=summary; that one result carries the forecast, tides, scores, advisories, hazards, lightning and source freshness.

All 105 tools by category

Start here (8)

Tool	What it does
`get_briefing`	A short headline + <=60-word body written from the live data (numbers validated against the fact sheet; falls back to a template when no model is available). source says claude/openai/template. Rate limited: may call an LLM on a cold cache.
`get_conditions`	The full conditions bundle for a named spot: current waves (ft, s, deg FROM), wind (kt), tide (ft MLLW), water temp (F), activity scores with reasons, 7-day hourly forecast, hi/lo tides, best windows, NWS alerts, rip/red tide/bacteria hazards, lightning and an AI briefing. Kitesurf: kiteboarding contains rider-specific weather screening and unverified launch status; supply kiteStyle, kiteExperience, kiteMinWindKt and kiteMaxWindKt. No overall kite score or verified launch is implied. Activities: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim scores are absent without shoreline observations; do not substitute other activity scores. Prefer view=summary unless you need every hour. boat= adds boat-specific chop comfort. For an arbitrary lat/lon use get_point_conditions. Start here for a current spot question with view=summary: this single result includes forecast, tides, scores, advisories, hazards, lightning and source status. Avoid duplicate hazard/tide calls unless a needed detail is absent. For beach questions, sea-model wave heights and NWS breaking-surf heights measure different things; their difference alone is not a forecast conflict. A swim no-go must not be followed by a recommendation to wade. Interpretation: omit boat unless the user supplied or confirmed it. Describe lightning as flashes observed or not detected in the stated window, never a clear/safe guarantee. Report unavailable/QC-failed sources even when freshness.stale=false; fresh does not mean every source is usable. Model sea height is not breaking surf height. Tide heights at different local MLLW gauges do not establish relative channel depths. High tide is not necessarily slack current. For kitesurfing use get_conditions with kiteStyle (freeride/waves/foil), kiteExperience and rider-supplied kiteMinWindKt/kiteMaxWindKt. Read kiteboarding for weather screening, gust spread and explicitly unverified launch status. Never infer the rider wind range, legal launch access or rescue coverage. Activity keys: kite, surf, skim (flatland), skim-wave (wave riding), paddle (flatwater paddleboard), sup-surf (SUP surf). Skim suitability is unscored without shoreline observations; missing scores must not inherit another activity. Offshore wind can favor surf while increasing paddleboard drift risk. A point depth cannot prove route clearance. Do not invent detection percentages, future readings, vessel ownership, or app settings instructions.
`get_data_coverage`	Published dataset inventory and verified spot coverage; distinguishes unavailable data.
`get_health`	Rolls up whether the ingest worker is running, which feed families (ndbc, coops, nws, openmeteo, goes19, coastwatch...) have stale sources, government dataset status and the GLM lightning feed. status is ok \	degraded \	down; HTTP 503 only when down. Check this before trusting 'no data' from other tools. detail=true lists every source.
`get_release_updates`	Read the current Gillby release version, date, supported MCP protocol and dated changes shared by the API and MCP. API URL versions are separate from product release versions.
`get_source_status`	Fresh, stale, unavailable and QC-rejected sources used by spot conditions.
`get_spot`	A single spot record plus now.scores (go/caution/nogo per activity for the current hour) when the worker has scored it.
`list_spots`	Every named Florida spot the app scores, with its lat/lon, kind, region and the NOAA stations used for it. Use the returned id with conditions, forecast, tides, hazards and briefing tools. include=status adds the current-hour go/caution/nogo band per activity. Use this for a map of verified coastal spots: the MCP app panel renders an interactive Florida map with selectable spots, nearby camera markers and conditions. Coordinates are geographic locations, not safe navigation routes.

Forecast and conditions (23)

Tool	What it does
`compare_spots`	Compare current conditions for up to five verified comma-separated spot IDs. Partial failures remain explicit.
`get_activity_scores`	Hourly published activity scores with reasons and vetoes. Missing activity scores are unscored.
`get_air_temperature`	Air temperature for a verified spot over the next hours. Includes timestamp, source status and explicit nulls when unavailable. Water temperature is F; atmospheric visibility is mi, not underwater visibility; current sign follows the assigned station convention.
