MCP Inspector

Run the official MCP Inspector locally and enter the indexed Streamable HTTP endpoint.

identify — Call this FIRST whenever you hold something other than a wallet address.
check_service_endpoint — Call this before connecting to a service, the way preflight_payment is called before sending money.
preflight_payment — Call this immediately before sending a payment, every time — not once per counterparty.
counterparty_check — Before paying or hiring an agent: what the chain records about that address.
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 Masumi by independent payers, dealings, ACP completion, whether its declared service answers, whether it pays its own payers back, and how recently it was paid.
counterparty_bulk — Check up to fifty addresses in one call, each with its observations: for an agent or a desk holding a list of counterparties before paying any of them.
