export_chapter_pdf · Mangadex MCP: Risk & Policy

WHAT IT DOES

What export_chapter_pdf does on Mangadex

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

WHY IT NEEDS A POLICY

Why export_chapter_pdf needs a policy

This tool writes/creates a new file locally (PDF export). While it modifies the local filesystem, the action is reversible (the file can be deleted), and there is no irreversible data destruction or external side effects beyond file creation. It does not delete data, execute arbitrary code, or move money. It is therefore Write rather than Destructive or Execute.

From the tool's definition Tool creates a new local PDF file from MangaDex chapter data ('Export an internal MangaDex chapter to a local PDF file'). The operation writes data to the user's filesystem.
