  • AI-judged instruction clarity (good).Pass

Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "pay_preflight" implies "pay" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail

MCP tools · 13 exposed · ~1,921 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 →

Install

How do I install the eu.vokko/vokko MCP server?

eu.vokko/vokko is a hosted endpoint at https://www.vokko.eu/api/v1/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.

Common questions

What is the eu.vokko/vokko MCP server?

eu.vokko/vokko is an MCP server listed in the public MCP registry as eu.vokko/vokko. Multi-protocol capability index: lookup, live refresh, pay-preflight, endpoint health. This page covers its hosted endpoint (https://www.vokko.eu/api/v1/mcp).

Is the eu.vokko/vokko MCP server safe to use?

eu.vokko/vokko scores 65 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 eu.vokko/vokko MCP server expose?

eu.vokko/vokko exposes 13 tools: lookup_host, refresh_host, participation_check, list_changes, refresh_host_protocol, and 8 more. Their descriptions and schemas cost roughly 1,921 tokens of context every time the server is loaded.

Does the eu.vokko/vokko MCP server require authentication?

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

Is the eu.vokko/vokko MCP server still maintained?

eu.vokko/vokko is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
