WHAT IT DOES

What generate_session_id does on Mcp Network Analyzer

AI agents use generate_session_id to create or update resources in Mcp Network Analyzer — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Network Analyzer environment.

WHY IT NEEDS A POLICY

Why generate_session_id needs a policy

This tool creates and returns generated session IDs, which is a Write-class action (reversible data creation). It has minimal blast radius since session IDs are typically ephemeral identifiers with no side effects on existing systems. The severity is low because misuse would only generate additional session IDs, not expose sensitive data, modify critical systems, or delete information.

From the tool's definition Tool description states it 'Generates a new unique session ID' — a creation operation that produces new data (session identifiers) for use with subsequent network capture operations.
