What it can do

Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.

  • whoami

    The authenticated caller's own profile (id, email, name, language). Takes no arguments. IDs are 6-character case-sensitive alphanumeric strings. Timestamps are UTC ISO 8601. Distances are integer meters. Durations are integer seconds.

  • trip_read

    Read the caller's voyages: list (the caller's OWN log), list the trips others shared with the caller (list_shared), get one trip, get its combined map, and get its public share link (get_share). `get` composes trip metadata with its crew, charter, and legs (there is no separate c

  • trip_write

    Change the caller's own voyages: create, update, delete, replace the full crew set (set_crew, PUT semantics), set or clear the charter (set_charter — a null charter clears it), announce the trip to its crew by email (announce), and turn its public link on or off (create_share, re

  • ship_read

    Read the caller's boats — a reusable, per-owner registry: list them all, or get one by id. The optional `flag` field is a ship's flag state as an uppercase ISO 3166-1 alpha-2 country code (e.g. "HR", "CZ"), or null. The optional `hullType` is 'monohull', 'catamaran' or 'trimaran'

  • ship_write

    Create, update or delete one of the caller's boats. The optional `flag` field is a ship's flag state as an uppercase ISO 3166-1 alpha-2 country code (e.g. "HR", "CZ"), or null. The optional `hullType` is 'monohull', 'catamaran' or 'trimaran', or null when unknown. Sending null fo

  • person_read

    Read the caller's private address book of people — crew and contacts: list them all, or get one by id. Personal data (birth date, passport) is never shared across users. `linkedAccount` reports whether this person has accepted an invitation and is linked to a Seamark account. `is

  • person_write

    Change the caller's private address book of people — crew and contacts (create, update, delete, unlink_account, mark_self, unmark_self, invite, accept_invitation). Personal data (birth date, passport) is never shared across users. `linkedAccount` reports whether this person has a

  • leg_read

    Read a trip's ordered legs: list them, or get one by id. A leg's `statsSource` is 'track' when its stats, coordinates and times are computed from a GPX track, 'manual' otherwise. On a trip someone else shared with the caller, `get` reads a leg but `list` does not — its legs are i

  • leg_write

    Change a trip's ordered legs: create, update, delete, reorder (a full leg-id permutation, reassigning seq 1..N), and fill a leg's wind from a weather service (fetch_weather). A leg backed by a track (statsSource: 'track') rejects an update that touches any computed stats/coordina

  • track_read

    Read a leg's GPX track: get the current track, and audit every kept/dropped point with its drop reason. Audit results are paged with offset/limit; a long track has many points. On a trip someone else shared with the caller, `get` reads the track; the audit stays the owner's. IDs

  • track_write

    Change a leg's GPX track: import raw GPX text (inline, capped at 5 Mi UTF-16 code units — that is what the schema counts, so it is roughly 5 MB for plain-ASCII GPX and no less for a file full of non-ASCII names; the server-side pipeline caps are separate: 32 MB of bytes AND at mo

  • stats

    The caller's lifetime logbook statistics across their whole log — the trips they own AND the trips shared with them as linked crew. Returns totals (distance in meters, moving/total time in seconds, days at sea, distinct shipmates, best sustained 1/5/10-minute speeds in knots, ave

  • resume

    The caller's sailing résumé — the record a charter company asks for before handing over a boat: one row per voyage the caller sailed with a known role, newest first, each with start and end date, the boat (name, model, length overall in centimeters as `loaCm`, hull type, or null

Common questions

Is Seamark safe?

It passed 2 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 –, and the latest version (1.6.0) reached the registry 2 months 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 on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

In the same category: QueryWeaver, Supabase, Neon, DBCode, Keboola MCP
