WHAT IT DOES

What get_session_changes does on Mcp Dev

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

RISK

Why get_session_changes is rated Low

This tool queries and retrieves historical session data (changes logged in the current session). It does not create, modify, delete, or execute any actions. The word 'Retrieve' explicitly confirms read-only semantics. The low severity reflects minimal blast radius if misused by an AI agent — it only exposes visibility into prior session activity without enabling any destructive or financial actions.

From the tool's definition Tool name is 'get_session_changes' and description states 'Retrieve all changes logged in the current session' — purely a retrieval operation with no modification or side effects.
