The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 3 tools
3 never probed 0 of 3 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • issue_receipt changes data unknown never probed

    Anchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana. Returns a permanent, publicly verifiable receipt (poll until outcome === "settled"). Costs 0.001 USDC via x402; if x402_payment_signature is omitted, returns the payment challenge instead (pay 0.001 USDC to the service address, then call again with the payment tx signature).

  • get_receipt reads unknown 3h ago

    Fetch full receipt details: digests, checks, outcome, amount, buyer, seller, timestamp, PDA. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

  "type": "object",
  "properties": {
    "receipt_id": {
      "type": "string",

    "payment_ref": {

  • verify_receipt reads unknown never probed

    Verify an AgentToll receipt against live Solana state: PDA owner must be the AgentToll program and the stored digest must match the receipt. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

    {
  "type": "object",
  "properties": {
    "receipt_id": {

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
