Japan Port Vessel Traffic MCP (AIS Position & ETA)
LocalAbout Japan Port Vessel Traffic MCP (AIS Position & ETA)
Japan Port Vessel Traffic MCP provides AIS-based vessel traffic data for major Japanese ports. It is intended for users tracking ships and port activity, with live positions, historical tracks, and ETA estimates.
Key features
- 01List 20 configured Japanese ports
- 02Retrieve live vessel positions and details
- 03Get historical tracks as GeoJSON
- 04Estimate ETA and delays
- 05Summarize port activity
Use cases
- 01Check vessels currently in a port
- 02Review a vessel's historical route
- 03Estimate arrival times and delays
- 04Monitor aggregated port activity
MCP support
The MCP server exposes tools for Japanese port catalogs, live vessel data, historical tracks, ETA estimates, and port activity summaries.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Tools
| Tool | Description |
|---|---|
list_japan_ports() | Catalog of 20 Japanese ports with bboxes |
get_vessels_in_port(port_code, limit=30) | Live vessel list within a port bbox |
get_vessel(mmsi) | Single-vessel latest position + static info |
get_vessel_track(mmsi, hours=24, interval="5m", limit=500) | Historical track as GeoJSON coordinates |
estimate_vessel_eta(mmsi, port_code=None) | ETA delay estimation |
get_port_overview(port_code, max_age_hours=6) | Aggregated port activity summary |
Quick examples
# List Japanese ports
ports = list_japan_ports()
# Vessels in Tokyo Bay
tokyo = get_vessels_in_port("JPTYO", limit=20)
# ETA delay for a specific vessel
eta = estimate_vessel_eta("431005321", port_code="JPTYO")
print(eta["delay_hours"])

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
