RECOMMENDED RULE

The rule that runs sap_chat_start_room safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sap, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sap_chat_start_room, this is the rule to start with:

sap_chat_start_room Rate-limited

sap_chat_start_room stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about sap_chat_start_room

What does the sap_chat_start_room tool do? +

Start an on-chain SAP chat room by creating the backing vault, session, and ledger if needed. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. 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 Write tool in the Sap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does sap_chat_start_room accept? +

sap_chat_start_room accepts 5 parameters: topic, roomId, roomKind, roomName, participants. The full parameter table on this page comes from the server's own tool schema.

How do I block sap_chat_start_room completely? +
