SudnoKontrol MCP

Model Context Protocol server for the Ukrainian national vessel registry — search vessels by registration number, name or owner, look up full registry records, and query aggregate statistics. Exposes the public data of the Державний судновий реєстр України (State Ship Registry) and the Суднова книга України (Ship Book).

Data is read-only and public — no API key required.

Hosted endpoint (recommended): https://api.sk.ukrfish.org/mcp (Streamable HTTP)
Project docs: https://sk.ukrfish.org/api-docs and https://sk.ukrfish.org/info/ai-agents

Tools

Tool	Description
`search_vessel_registries`	Free-text + structured search across both national registries. Deterministic ordering: exact registration-number matches first. Supports Cyrillic/Latin and separator-insensitive numbers (`УПС-0129` ≡ `УПС 0129` ≡ `UPS-0129`).
`lookup_vessel`	Exact vessel lookup by normalized registration number. Returns full registry record.
`get_registry_stats`	Aggregate public vessel counts ("how many vessels...").
`get_dataset_metadata`	Dataset context: sources, import dates, record counts, fields.

Every search/lookup result includes a web_url → https://sk.ukrfish.org/registry?vessel=<reg> pointing to the public vessel information page.
