Agent Verification Utility is an MCP server with 5 tools an agent can call, among them describe_verify_evidence, get_revenue_goal_status, prepare_verify_evidence_purchase. It answers at https://agent-economy.kgninja.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Deterministic JSON checks with signed evidence and x402-paid execution
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
describe_verify_evidence | Describe when deterministic verification is useful, when it is not, free request validation, recipes, limits, and the explicit paid MCP path. |
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. |
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. Inputs: idempotency_key, intent |
quote_verify_evidence | Validate a complete verification request and return a free quote when the margin policy passes. Inputs: idempotency_key, intent |
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. Inputs: idempotency_key, intent |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://agent-economy.kgninja.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
