generate_work_notes · ServiceNow- MCP: Risk & Policy

WHAT IT DOES

What generate_work_notes does on ServiceNow-MCP

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

WHY IT NEEDS A POLICY

Why generate_work_notes needs a policy

The tool creates new data (work notes) that are added to ServiceNow records. While this is reversible (work notes can be deleted or edited), it modifies the audit trail and record state. This is a Write operation rather than Read (which would only retrieve existing work notes).

From the tool's definition Tool description states 'Generate AI-drafted work notes' which creates new content (work notes) attached to records. Work notes are persistent modifications to ServiceNow records that document actions and decisions.
