A new agent mandate is created, signed by both parties, and minted as an immutable ERC-721 contract on Base L2, establishing legal authorization for the agent.
The agent uses the MCP server to create a contract using a specific template (e.g., d1-general-auth) with defined parameters like scope and spending limits. It then facilitates the handshake process where the counterparty accepts the terms, followed by ECDSA wallet signatures from both parties to activate the mandate and trigger on-chain minting.

- Source quote: "The MCP server exposes six tools -- ambr_list_templates , ambr_create_contract , ambr_get_contract , ambr_get_contract_status , ambr_verify_hash , and ambr_agent_handshake -- so any MCP-compatible agent can manage mandates natively."
