The rule that runs blinks_buildActionUrl 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 blinks_buildActionUrl, this is the rule to start with:
blinks_buildActionUrl is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Sap, apply this rule, and every blinks_buildActionUrl call is checked against it from then on.
Questions about blinks_buildActionUrl
Build and optionally wrap a Solana Action URL for sharing as a Blink. SAP MCP context: Protocol blinks; operation class read. Use for Solana Actions and Blinks metadata fetch, validation, and POST action preparation. Preview and validate actions before signing or submitting transactions through SAP transaction tools. SAP MCP execution guidance: Intent: SAP MCP tool workflow. 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 Read tool in the Sap MCP Server, which means it retrieves data without modifying state.
