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.

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 77 other origins: the figure is the gateway's, not this listing's alone.

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.

  • quantumwerk_qkd_key_request reads unknown never probed

    Compares caller-supplied Alice and Bob bases, retains matching-basis positions, calculates the quantum bit error rate over caller-selected revealed positions, and returns only a digest and count for remaining demonstration bits. It neither exchanges quantum states nor creates a secret key: all submitted bits are disclosed to this service and must never be used as production key material.

It preserves only these local identities; it does not commute gates, model hardware topology, synthesize arbitrary unitaries or prove global optimality.

_ 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
100%

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.
