Agent Embassy MCP
Provides trust infrastructure for the agent economy, enabling agents to pay for work and generate machine-readable proof of transactions that is verifiable indefinitely for agents, people, and businesses.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

register_recovery — Register Recovery
Escrow an encrypted recovery blob: stored opaquely — we cannot decrypt it — for operator review, signed receipt proving its hash; quorum_rules govern release. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $1.00, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/recovery/register.
