WHAT IT DOES

What save_presentation does on ContextForge MCP Gateway

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

WHY IT NEEDS A POLICY

Why save_presentation needs a policy

The save action creates or overwrites a file artifact, making it a Write operation rather than Read (no side effects) or Execute (no code execution). Severity is medium because file overwrites could lose previous work but are reversible through undo/recovery mechanisms and lack the irreversibility of Destructive operations.

From the tool's definition Tool description states 'Save the presentation to a file', which creates or modifies a file on the filesystem.
