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.

  • Project docs: https://sk.ukrfish.org/api-docs and https://sk.ukrfish.org/info/ai-agents
  • Discovery: https://sk.ukrfish.org/llms.txt

Tools

ToolDescription
search_vessel_registriesFree-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_vesselExact vessel lookup by normalized registration number. Returns full registry record.
get_registry_statsAggregate public vessel counts ("how many vessels...").
get_dataset_metadataDataset 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.
