pdf_manipulate · MCP Workspace Server MCP: Risk & Policy

WHAT IT DOES

What pdf_manipulate does on MCP Workspace Server

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

WHY IT NEEDS A POLICY

Why pdf_manipulate needs a policy

The tool can extract text (Read) but also merge and split PDF files, which constitutes writing/modifying data. Merging creates new combined files and splitting creates new separate files from an original — these are reversible write operations, not destructive. The most severe applicable category is Write.
