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

describe
describe_verify_evidence
Describe when deterministic verification is useful, when it is not, free request validation, recipes, limits, and the explicit paid MCP path.
prepare
prepare_verify_evidence_purchase
After a successful free precheck, create or reuse a bound quote and return the exact HTTP request that will produce the x402 challenge. Do not pay until the binding, price, network, asset, payTo, and expiry match local policy.
quote
quote_verify_evidence
Validate a complete verification request and return a free quote when the margin policy passes.
revenue
get_revenue_goal_status
Read the active revenue goal, measured funnel, contribution margin, and the next bounded improvement recommendation. This tool never changes price, spends funds, or sends messages.
verify
verify_evidence
Run deterministic checks and return Ed25519-signed evidence after one explicitly authorized x402 payment. A free precheck receipt and a matching bound payment requirement are required before signing.

Agent Verification Utility — questions

Answers built from our own checks of this server.

What can Agent Verification Utility do?
It exposes 5 tools, read directly from the server on our last check. Among them: describe_verify_evidence, get_revenue_goal_status, prepare_verify_evidence_purchase, quote_verify_evidence, verify_evidence. 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 Agent Verification Utility 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 283 ms. The bar chart above shows every period we have measured.
How do I connect Agent Verification Utility?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Agent Verification Utility need an API key?
No. Agent Verification Utility completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agent Verification Utility?
It answers our handshake in 283 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
