Tools observed via MCP handshake

identify — Call this FIRST whenever you hold something other than a wallet address. Give it a transaction hash, an http(s) URL, a hostname or an ERC-8004 registration numb
check_service_endpoint — Call this before connecting to a service. Give it the http(s) URL of an MCP or A2A endpoint and it says who declares it, whether our daily probe reached it, wha
preflight_payment — Call this immediately before sending a payment, every time — not once per counterparty. It weighs THIS payment (the amount, the chain, the endpoint) against wha
vault_exits — Before putting capital somewhere, ask what has actually LEFT it. Every liquidity figure elsewhere is a level at an instant — how much could be withdrawn right n
evidence_for — Everything we hold about one subject, as edges, each carrying where it came from. Use it when you need to explain a decision rather than just make one, or to se
evaluate_action — Call this when you are about to DO something and need one answer you can act on: pay an address, connect to an MCP server, call a tool, or put capital into a va
list_policies — The policies evaluate_action can be run under, in full: every rule, its id and the sentence it checks. Published deliberately, including to the agents being eva
counterparty_check — Before paying or hiring an agent: what the chain records about that address. Independent payers (counterparties that paid it and were never paid back), the ones
vault_check — Before putting capital into a vault: what the record shows about it. The headline is what a holder ACTUALLY EARNED set against the advertised rate, with the ris
find_vaults — Find a vault by what it has DONE rather than what it is called. Free. The filter worth knowing is `earned`: `short` returns the vaults where a holder earned LES
operator_check — The question that follows vault_check: who runs the money, and how much of it is their own. Free. Read `ownShare` with its limits, which travel inside it: the l
list_vaults — The vaults we read, so a caller holding a name rather than a slug can find the one it means. Free. Absence from this list means we do not read that vault, never
find_agents — Find agents to hire by what the chain records rather than what they claim: filter every address ever paid on x402, Virtuals ACP, the Olas mech marketplace or Ma
counterparty_history — How one agent’s record has moved: dealings, independent payers, concentration and delivery, day by day. PAID, one cent a call over x402 — the median price of th
