Contribution Exchange MCP — discover and act on Contribution Exchange opportunities. Read-only tools: exchange_discover_domain (check if a domain has an Exchange profile), exchange_get_policy (fetch domain policy), exchange_preflight (advisory policy evaluation — no state change), exchange_list_signals (domain-published work signals), exchange_get_signal, exchange_get_attempt. Mutation tools (require auth): exchange_propose (unsolicited proposal — creates a non-binding proposal, NOT a Commitment), exchange_create_attempt, exchange_submit_attempt, exchange_create_proposal_from_attempt.…

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.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
standard-record unknown never probed
Create a sigrank/0.1-draft record from I/O/W/R telemetry. The base record excludes Construction, Build Archetypes, and RS05.
discover-peers unknown never probed
Find mentors (1-2 class tiers above with similar cascade shapes + pillar deltas), peers (same tier), and complementary operators (whose strength is your weakness). Uses enrolled device identity — no codename needed.
leaderboard unknown never probed
Get the current top-N AI operator rankings by Yield (Υ)
operator unknown never probed
Get a single operator's full profile, metrics, and rank
metrics unknown never probed
Get definitions and formulas for SigRank core and product metrics
hall-of-signal unknown never probed
Get all-time records and badge holders

Head-to-head comparison of two operators
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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
