WHAT IT DOES

What add_pdf_content does on oxidize-pdf MCP Server

WHY IT NEEDS A POLICY

Why add_pdf_content needs a policy

The tool name 'add_pdf_content' suggests it adds or inserts content into a PDF document, which is a reversible modification operation (Write category). This aligns with the broader PDF manipulation capabilities shown by sibling tools. Severity is medium because modifying PDFs could corrupt documents or introduce unintended content, but changes are typically reversible via undo or re-processing.

From the tool's definition Tool name 'add_pdf_content' combined with sibling tools including 'create_pdf', 'save_pdf', and 'manipulate_pdf' indicates content modification. The description is empty, limiting direct evidence.
