Vokko does not always answer

Over the last week it answered 20.8% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

refresh

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.

refresh_host_protocol

Paid live probe of one protocol. Args domain, protocol (ucp, mcp, a2a, x402, and the other detector ids). Unpaid calls return HTTP 402 at $0.005 USDC on Base. Full-host refresh_host stays $0.02.

refresh_hosts_batch

Paid live re-probe of up to 10 hosts. Args domains (string array) and mode "full". Unpaid calls return one HTTP 402. Price is $0.01 + $0.002 × N USDC on Base.

changes

list_changes

Newest-first drift. Anonymous: last 5 summaries. Subscriber for that origin: full history.

endpoint

endpoint_health

Is this paid API up, and what does it charge right now? Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.

lookup

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.

participation

participation_check

Cached participation status and evidence. Not a legal finding.

pay

pay_preflight

Can an agent pay at this host? Rails, endpoint, price, freshness. Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.

payable

find_payable

Alphabetical hosts whose index row includes x402. Evidence only. Not a rank and not a payable proof.

payto

payto_check

Does this payTo address belong to the domain? Evidence, not a guarantee. Unpaid calls return HTTP 402 at $0.002 USDC. Same resource URL as the REST route.

provider

find_provider

Cheapest live x402 providers for a task. Placement is never sold. Unpaid calls return HTTP 402 at $0.005 USDC. Same resource URL as the REST route.

seller

seller_trust

Observational x402 seller trust score for a payTo and network. Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.

verify

verify_receipt

Did this USDC transfer settle to the expected address and amount? Unpaid calls return HTTP 402 at $0.001 USDC. Same resource URL as the REST route.

Vokko — questions

Answers built from our own checks of this server.

What can Vokko do?

It exposes 13 tools, read directly from the server on our last check. Among them: endpoint_health, find_payable, find_provider, list_changes, lookup_host, participation_check and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Vokko working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 107 ms. The bar chart above shows every period we have measured.

Is Vokko still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Vokko?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Vokko need an API key?

Yes. Every time we knock, Vokko answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Vokko?

It answers our handshake in 107 ms on average, which is faster than 96% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
