  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass

Install

How do I install the SudnoKontrol MCP server?

SudnoKontrol is a hosted endpoint at https://api.sk.ukrfish.org/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 4 exposed · ~340 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the SudnoKontrol MCP server?

SudnoKontrol is an MCP server listed in the public MCP registry as org.ukrfish.sk/sudnokontrol. Ukrainian vessel registry: search by number/name/owner, full records, stats. No API key required. This page covers its hosted endpoint (https://api.sk.ukrfish.org/mcp).

Is the SudnoKontrol MCP server safe to use?

SudnoKontrol scores 87 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the SudnoKontrol MCP server expose?

SudnoKontrol exposes 4 tools: search_vessel_registries, lookup_vessel, get_registry_stats, get_dataset_metadata. Their descriptions and schemas cost roughly 340 tokens of context every time the server is loaded.

Does the SudnoKontrol MCP server require authentication?

No. We connected to SudnoKontrol without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the SudnoKontrol MCP server still maintained?

SudnoKontrol is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
