## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 13 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1921 tokens (~147/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 70/100
  - Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 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.
  - An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

- `tx` (string): Alias of txHash. Same 0x-prefixed 64-hex format. If both are sent they must match case-insensitively.
- `txHash` (string): 0x-prefixed 64-hex-character transaction hash. Required by the validator (tx is an accepted alias).

## 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.
