Registrar

Builds unsigned EVM transaction payloads for ERC-8004 registry operations, returning a raw transaction object with to, data, and value fields ready for signing. Inputs include operation (deploy, register, update), optional payload JSON string, agentName, metadataURI, registryAddress, and optional paymentValue Wei string, with conditional requirements per operation documented in parameter descriptions. The tool must always return output that strictly validates against the system-provided structured output schema, with no extra fields or type mismatches.
