createShareLink · GROWI MCP Server MCP: Risk & Policy

WHAT IT DOES

What createShareLink does on GROWI MCP Server

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

WHY IT NEEDS A POLICY

Why createShareLink needs a policy

Creating a share link is a reversible modification that generates new data (the link resource) without destroying or executing arbitrary operations. It can be undone via deleteShareLinkById or deleteShareLinks. The severity is medium because share links can expand access to wiki content, potentially exposing information depending on what pages are shared, but the operation itself is not destructive or financial.

From the tool's definition Tool name 'createShareLink' and description 'Create a share link for a page' indicate creation of a new resource (a share link).
