Overview

AI-generated overview

Local MCP server that gives an assistant live AIS vessel positions, tracks and ETA estimates for 20 major Japanese ports.

What you can do
  • List the 20 pre-configured Japanese ports with their bounding boxes
  • Look up live vessels inside a port and fetch a single vessel's latest position and static details
  • Retrieve historical vessel tracks as GeoJSON coordinates
  • Estimate ETA and delay by comparing AIS-reported and speed-projected arrival
  • Summarize port activity by vessel type, flag and status
When to use it
Useful when you want an assistant to answer questions about ship traffic in Japanese ports — which vessels are in port, where a ship is, its recent track, or whether it is running late — without signing up for a commercial AIS feed.
Requirements
Runs as a local stdio process; the README installs it from the repository with uv (or pip) and starts it via uv run. No API key is declared for the anonymous tier, and no environment variables or headers are declared. Network access to the Open Waters AIS API is needed.
Before you install
Data comes from an aggregate of community AIS receivers, AISHub and aisstream, so coverage and accuracy are not official or guaranteed. Requests go to a third-party AIS API. The README also points to paid Apify and Gumroad listings, which are separate from this local server.

Installation

In SourceWeft

  1. Open Japan Port Vessel Traffic MCP (AIS Position & ETA) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
