MetaMask, in the top right, signs you in โ it maps your address to a Hedera account so this console knows who you are. It cannot pay: x402 settles with a partially-signed native Hedera transfer, and MetaMask only signs Ethereum-prefixed messages. The Hedera keypair below is what actually buys โ you hand it to the MCP bridge, which answers the 402s on your client's behalf. Issue it once, keep it local, and never paste it into this dashboard.
An agent needs one credential: a Hedera keypair. No signup, no API key. The service mints a testnet account, funds it and keeps no copy of the key.
discover, compute_providersA paid call answers 402 with amount, payTo and fee payer, then stops. That is the protocol working, not an error.

Then ask Claude to run `discover` โ it lists every priced tool with no credentials.
