export_structure · Doc MCP: Risk & Policy

WHAT IT DOES

What export_structure does on Doc

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

WHY IT NEEDS A POLICY

Why export_structure needs a policy

This tool creates/generates structured output files (JSON or Markdown) from document analysis. While it doesn't modify existing data irreversibly, it does write/create new files which constitutes a Write operation. Severity is medium because file exports could potentially consume storage or overwrite existing files if not properly handled, but the operation is typically reversible.

From the tool's definition Tool name 'export_structure' with description 'Export document structure as JSON or Markdown file' indicates creation or generation of new files/exports. The verb 'export' combined with 'to JSON or Markdown file' suggests the tool writes output data to files.

Verdict

export_structure Rate-limited

export_structure 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.
