It fits the Write category (creates/modifies data reversibly). Severity is medium because misuse could add misleading or malicious annotations to documents, but the change is non-destructive and can be corrected or removed.

From the tool's definition Tool name 'annotate_pdf' indicates modification of PDF documents. Server context shows tools for 'PDF generation, parsing, splitting, merging, and manipulation'.
