Available Tools

The DataDocked MCP Server provides 18 tools for querying maritime data.

Basic Tools

Single-endpoint operations that query one API endpoint.

Tool	API Endpoint	Identifier	Credits	Rate Limit
`track_vessel`	get-vessel-location	IMO or MMSI	1	100/min
`track_vessels_bulk`	get-vessels-location-bulk-search	IMO or MMSI	1/vessel	15/min
`search_vessel_by_name`	vessels-by-name	Vessel name	1	50/min
`get_vessel_history`	get-vessel-historical-data	IMO or MMSI	5/day	15/min
`search_vessels_by_area`	get-vessels-by-area	lat, lon, radius_km	10	50/min
`get_vessel_details`	get-vessel-info	IMO or MMSI	5	15/min
`get_vessel_specs`	get-vessel-particulars	IMO or MMSI	1	50/min
`get_vessel_engine`	get-vessel-engine-data	IMO or MMSI	1	50/min
`get_vessel_management`	get-vessel-management-data	IMO or MMSI	1	50/min
`get_port_calls`	port-calls-by-vessel	IMO or MMSI	5	15/min
`get_port_traffic`	port-calls-by-port	Port code	50	15/min
`get_psc_inspections`	vessel-mou	IMO only	3	15/min
`get_vessel_weather`	get-vessel-weather	IMO or MMSI	1	15/min

get_vessel_details returns comprehensive data including specifications, engine info, and management details in a single call - often eliminating the need for separate get_vessel_specs, get_vessel_engine, and get_vessel_management calls.

get_psc_inspections requires IMO number only. MMSI is not accepted.

Compound Tools

Multi-endpoint operations that combine multiple API calls into comprehensive reports.

Tool	Description	Credits
`vessel_intelligence_report`	Complete vessel dossier	~13
`fleet_dashboard`	Fleet status with vessel details	~6/vessel
`voyage_analysis`	Current voyage with weather & history	~38
`port_activity_analysis`	Rich port traffic analysis	varies
`risk_assessment`	Composite risk score	~10
`area_intelligence`	Region with full vessel profiles (circular search)	10 + 5/vessel

Area Search

Area-based searches use circular search with center coordinates and radius:

latitude, longitude, radius_km

Maximum radius is 50 km. For larger areas, use multiple searches with different center points.

Example regions:

Region	Center Lat	Center Lon	Radius
Singapore Strait	1.25	103.75	50 km
Strait of Hormuz	26.5	56.5	50 km
English Channel (Dover)	51.1	1.3	50 km
Rotterdam Port	51.9	4.5	30 km

Usage Examples

Track a Vessel

"Where is the Ever Given right now?"

Uses track_vessel (1 credit) to return:

Current position (lat/lon)
Speed and course
Destination and ETA
Navigation status

Get Complete Vessel Intelligence

"Generate a full dossier on vessel 9811000"

Uses vessel_intelligence_report (~13 credits) combining:

Position tracking
Full vessel details (specs, engine, management)
Port call history
PSC inspection records (requires IMO)

Search an Area

"Show me all tankers within 50km of Singapore"

Uses search_vessels_by_area (10 credits) with circular search to find vessels in the specified region, filtered by vessel type.

Credit Management

Check your credit balance anytime by asking: “How many credits do I have left?”

Credits are deducted when a tool executes. The MCP server shows estimated costs before running compound operations. To disable credit warnings:

export DATADOCKED_SHOW_COST=false
