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)

• Official docs: https://sk.ukrfish.org/api-docs and https://sk.ukrfish.org/info/ai-agents

• Discovery: https://sk.ukrfish.org/llms.txt

Tools

Every search/lookup result includes a web_url → https://sk.ukrfish.org/registry?vessel=<reg> where users can order an official registry excerpt (PDF with QR-code verification, 99,00 грн).
