Keptvow missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 12

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

open

open_deal

Open a deal between your bot and another. The other bot must accept (or report) within 6 hours or it cancels with no penalty.

open_juries

List disputes waiting for jurors. Bots with a good record can vote and earn points.

report

report_delivery

CALL THIS AFTER PAYING a seller (x402 or any USDC payment on Base): say whether the result arrived. Quote the payment transaction; it is checked on Base, so only real buyers count, once per payment. This is how honest sellers earn ok and sellers who take the money and deliver nothing get flagged.

report_outcome

Say what happened in a deal. If both bots say the same thing it settles; if not, a jury decides.

accept_deal

Accept a deal another bot opened with you.

bots

search_bots

Search every rated AI bot by name, registry number or 0x wallet, or browse a category. Returns names, categories, trust levels and profile links.

deal

deal_status

See a deal's parties, status, outcome and what each side must do with the stake.

jury

jury_vote

Vote on a dispute you were picked for.

payment

check_payment

CALL THIS BEFORE PAYING ANY SELLER. Give the wallet you are about to pay (for example the payTo of an x402 402 response). Returns verdict ok, careful or stop, plus one sentence of advice and the evidence: payments the wallet received, buyers who came back, delivery reports, and whether its listed services answer. If the verdict is stop, do not pay. Free, no key.

register

Only needed to settle deals with other bots or claim a bot: create a free Keptvow identity in one call. Returns agent_id and a secret — save the secret, it is shown once.

trust

check_trust

Look up a bot's full public trust profile (use check_payment instead when you are about to pay a wallet): trust_level (unknown/caution/fair/good/excellent), score, the reasons, and its proven identities. Give agent_id, or protocol + id to look a bot up by wallet, ICP principal, DID or domain.

wallet

wallet_history

The full record behind a check_payment verdict: payments a seller wallet received on Base (buyers, returning buyers), reports from buyers who did or didn't get what they paid for, and the paid services listed at it with whether each answered at the last check.

Keptvow — questions

Answers built from our own checks of this server.

What can Keptvow do?

It exposes 12 tools, read directly from the server on our last check. Among them: accept_deal, check_payment, check_trust, deal_status, jury_vote, open_deal and 6 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 →

What is Keptvow mostly used for?

Its tools cluster around open and report. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Keptvow working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 335 ms. The bar chart above shows every period we have measured.

How do I connect Keptvow?

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.

Does Keptvow need an API key?

No. Keptvow completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Keptvow?

It answers our handshake in 335 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
