VesselAPI MCP Server
An MCP (Model Context Protocol) server that exposes maritime data from the VesselAPI to AI assistants like Claude Desktop, Cursor, Windsurf, and Claude Code.
Prerequisites
- Sign up at dashboard.vesselapi.com
- Create an API token in your dashboard
- Use the token as
VESSELAPI_API_KEYin the configuration below
Resources: Documentation | API Explorer | Dashboard | Contact Support
Features
- 23 tools covering vessels, ports, location search, emissions, and maritime safety
- Vessel search, positions (single and batch), ETA, classification, ownership, emissions, inspections, and casualties
- Port search, details, port events (arrivals/departures), and global port event search
- Geographic vessel search (bounding box and radius)
- NAVTEX maritime safety messages
- Manual pagination to control API quota usage
Hosted deployment
A hosted deployment is available on Fronteir AI.
