AI agents call actual_session_close as a supporting operation in Actual workflows.

RISK

Why actual_session_close is rated Low

This tool closes an MCP session (a connection/resource handle), not financial data or user content. It is a session/resource management operation — it doesn't read, write, execute, or delete user data, nor does it involve financial transactions. It is closest to 'Other' as it manages infrastructure/connection state rather than application data.
