FAQ

Questions about sap_build_agent_register_transaction

What does the sap_build_agent_register_transaction tool do? +

Hosted-safe unsigned builder for register_agent. Browser runtimes preview this transaction, the owner wallet approves and signs locally, then it goes through the Steve signed-transaction submit relay or sap_payments_finalize_transaction. Pays the 0.1 SOL SAP protocol registration fee from the signing wallet. Keypair bytes never leave the user device. SAP MCP context: Direct synapse-sap-sdk wrapper served by this MCP. Read tools return on-chain state; write tools require signer policy, configured RPC, and the active SAP profile. SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required. It is categorised as a Financial tool in the Sap MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
