wtf_freshell · Wtf MCP: Risk & Policy

WHAT IT DOES

What wtf_freshell does on Wtf

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

WHY IT NEEDS A POLICY

Why wtf_freshell needs a policy

The tool archives the current incident and initializes a new journal session. Since previous entries are explicitly preserved, this is not destructive. It modifies state by closing/archiving the current incident context and creating a new one, making it a Write operation. Misuse could cause loss of active incident context mid-investigation, hence medium severity.

From the tool's definition Archive the current incident and start a fresh journal. Previous entries are preserved in the database.
