Model Context Protocol server providing tools to access VesselAPI endpoints

VesselAPI MCP Server

CInpmNodeLicense: MIT

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

  1. Sign up at dashboard.vesselapi.com
  2. Create an API token in your dashboard
  3. Use the token as VESSELAPI_API_KEY in the configuration below

Resources: Documentation | API Explorer | Dashboard | Contact Support

Features

  • 16 tools covering vessels, ports, location search, and maritime safety
  • Vessel search, positions, ETA, classification, ownership, emissions, inspections, and casualties
  • Port search, details, and port events (arrivals/departures)
  • Geographic vessel search (bounding box and radius)
  • NAVTEX maritime safety messages
  • Manual pagination to control API quota usage

Quick Start

No installation required — just configure your AI client with npx:

{
  "mcpServers": {
    "vesselapi": {
      "command": "npx",
      "args": ["-y", "vesselapi-mcp"],
      "env": {
        "VESSELAPI_API_KEY": "your-api-key"
      }
    }
  }
}

Configuration

Add the JSON above to the config file for your client:

Client Config file
Claude Desktop ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)
Cursor .cursor/mcp.json or ~/.cursor/mcp.json
Claude Code .claude/settings.json or ~/.claude/settings.json
Windsurf ~/.codeium/windsurf/mcp_config.json

Tools

Vessel Tools

Tool Description
search_vessels Search vessels by name, IMO, MMSI, flag, type, or callsign
get_vessel Get detailed vessel information
get_vessel_position Get current vessel position (lat/lon, speed, heading)
get_vessel_eta Get vessel estimated time of arrival
get_vessel_classification Get classification details (class society, surveys, hull)
get_vessel_ownership Get ownership details (owner, manager, operator)
get_vessel_emissions Get emissions data (CO2, fuel consumption)
get_vessel_inspections Get port state control inspections
get_vessel_casualties Get marine casualty records

Port Tools

Tool Description
search_ports Search ports by name, country, type, or region
get_port Get port details by UN/LOCODE
get_port_events Get arrivals/departures for a port
get_port_events_by_vessel Get port events for a vessel

Location Tools

Tool Description
get_vessels_in_area Find vessels in a bounding box
get_vessels_in_radius Find vessels within a radius of a point

Safety Tools

Tool Description
get_navtex_messages Get NAVTEX maritime safety messages

Pagination

All list endpoints support limit and nextToken parameters for manual pagination. When more results exist, the response includes a nextToken — pass it in the next call to get the next page.

Development

git clone https://github.com/vessel-api/vesselapi-mcp.git
cd vesselapi-mcp
npm install
npm run build

npm run build        # Build the server
npm run typecheck    # Type-check without emitting
npm run clean        # Remove build artifacts

Testing with MCP Inspector
