pdf_export · RC Engine MCP: Risk & Policy

WHAT IT DOES

What pdf_export does on RC Engine

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

WHY IT NEEDS A POLICY

Why pdf_export needs a policy

This tool generates and writes new HTML files to the filesystem based on input markdown. It is a reversible, non-destructive write operation—the original markdown files remain unchanged, the created HTML files can be deleted, and the operation has no side effects beyond file creation. It does not read sensitive data beyond what users explicitly provide, execute arbitrary code, delete anything, or move money.

From the tool's definition Tool description states it 'converts' markdown files into styled HTML and 'saves the HTML' to a directory (rc-method/exports/), creating new files as output.

Verdict

pdf_export Rate-limited

pdf_export stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
