WHAT IT DOES

What actual_session_list does on Actual

AI agents call actual_session_list to retrieve information from Actual without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why actual_session_list is rated Low

This tool only queries and retrieves information about active sessions and their status. It performs no mutations, executions, or destructive actions. The blast radius is minimal — an AI agent listing sessions cannot cause harm beyond potentially gathering metadata about the Actual Budget system's state. The activity is purely informational.

From the tool's definition Tool name contains 'list' and description states 'List all active MCP sessions' — a retrieval operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs actual_session_list safely

actual_session_list Allowed

actual_session_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
