Datalastic Vessel Tracking & Maritime Intelligence

by com.datalastic

Vessel ownership & management chain

intel_ownership

Reveal the commercial control behind a vessel: beneficial owner, operator, technical manager and commercial manager — each with its company IMO and country — plus the P&I club and flag. Look up one vessel by imo or name, or turn the question around and pass a company name (beneficial_owner, operator, technical_manager or commercial_manager) to list every vessel that company controls. Part of the Maritime Reports add-on.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
imoNoVessel IMO number (exactly 7 digits) to look up.
nameNoVessel name to look up (use when the IMO is unknown).
operatorNoCompany name of the operator; returns every vessel under that operator.
updated_fromNoOnly include records updated on or after this date (YYYY-MM-DD).
beneficial_ownerNoCompany name of the beneficial owner; returns every vessel under that owner.
technical_managerNoCompany name of the technical manager; returns every vessel under that manager.
commercial_managerNoCompany name of the commercial manager; returns every vessel under that manager.

A4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It discloses the tool returns ownership details and can list vessels, implying read-only behavior. However, it omits details on rate limits, authorization requirements, or behavior when no results are found.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loading the main purpose and covering key functionality without unnecessary words. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema, return values are covered. The description covers primary functionality and parameters. Lacks mention of pagination or limits when listing vessels by company, but overall complete for the tool's purpose.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds context by explaining the reverse lookup capability, but does not significantly extend meaning beyond the schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it reveals the commercial control behind a vessel, listing specific entities (beneficial owner, operator, manager, P&I club, flag). It distinguishes itself by offering both vessel lookup and reverse company lookup, differentiating from sibling tools like intel_companies.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly provides two usage modes: lookup by vessel (IMO or name) or by company name to list vessels. It implies context by stating 'Part of the Maritime Reports add-on,' but lacks explicit when-not-to-use guidance or alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.2/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose: vessel tracking (get_vessel, get_vessel_pro, get_vessel_history, get_vessel_info, estimated_vessel_position), registry search (find_vessels, find_ports), port details (get_port), weather (get_weather), sea route (sea_route), async reports (report_*), and intelligence modules (intel_*). Even similar tools like find_vessels vs get_vessel are well-differentiated by their descriptions.

Naming Consistency5/5

All tool names follow a consistent lowercase underscore pattern with a verb_noun structure (e.g., get_vessel, find_ports, sea_route). The intel_* tools use a uniform prefix for intelligence operations, maintaining predictability across the set.

Tool Count3/5

With 25 tools, this server is at the upper boundary of the borderline range. While the tools are well-organized and necessary for the comprehensive maritime intelligence domain, the count feels slightly heavy compared to an ideal 3-15 tool scope.

Completeness5/5

The tool surface is remarkably complete: it covers vessel tracking (live, historic, estimated), registry search, port details, weather, sea route calculation, async report management, and a full suite of intelligence reports (casualties, inspections, ownership, etc.). There are no obvious gaps for maritime vessel tracking and intelligence tasks.
