lookup_host | Cached host report. Free. Does not 402. Body includes cache.presenceStale, cache.callabilityStale, and refresh (payable live re-probe: priceUsd, network, rest.url, mcp.tool refresh_host). Does not re-probe. params: domain* |
refresh_host | Paid live re-probe named by lookup_host refresh.rest. Unpaid calls return HTTP 402 with x402Version and accepts. Price matches refresh.priceUsd ($0.02 USDC on Base by default). Vokko never pays the target. params: domain* |

Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
