@pipeworx/digitraffic-ais

Live vessel positions in Finnish and Baltic waters, from Fintraffic's AIS receivers. Keyless.

Tools

• ais_vessels_near(...) — vessels within a radius of a point, with position, speed, course, navigational status and type.

• ais_area_count(...) — how many vessels are in an area, broken down by ship type.

• ais_vessel(...) — latest position and voyage details for one vessel by MMSI.

None.

Coverage

Regional, not worldwide. Fintraffic's receivers cover Finland and the surrounding Baltic — Gulf of Finland, Gulf of Bothnia, Archipelago Sea, Åland — with fringe reception toward Estonia and Sweden. Every tool description says so, because a worldwide vessel question routed here would return a confidently empty answer. For coverage beyond the Baltic use live_ships_in_area (vessel-tracking), which reaches wherever community receivers exist.

Gotcha worth knowing

The API requires Accept-Encoding: gzip — requesting identity encoding returns HTTP 406. The pack also sniffs the gzip magic bytes (0x1f 0x8b) rather than trusting the Content-Encoding header, because Node/undici transparently decompresses while leaving the header in place, and double-decompressing throws Z_DATA_ERROR.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "digitraffic-ais": {
      "url": "https://gateway.pipeworx.io/digitraffic-ais/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Digitraffic Ais data" })

The gateway picks the right tool and fills the arguments automatically.
