It performs no modifications, deletions, or external operations. The output is informational only, making it a standard Read operation with low severity since misuse would only expose financial data visibility, not alter or delete records. From the tool's own definition: "Tool name is 'list_expenses' and description states it 'List[s] business expenses' with filtering and summary—purely retrieval operations with 'no side effects' characteristic of Read category." ## Use case AI agents call list_expenses to retrieve information from Businys 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**.
