It is a read-only operation that gathers data about approval gates. While the context involves approval workflows, the tool itself performs no write, execute, destructive, or financial actions—it only retrieves metadata about rules. From the tool's own definition: "The tool name 'list_approval_rules' and description explicitly state it 'List[s] approval rules', which is a retrieval operation with no side effects. The phrase 'Use this before changing' indicates it is informational prior to taking other actions." ## Use case AI agents call list_approval_rules to retrieve information from Sanka MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
