What createPage does on GROWI MCP Server

AI agents use createPage 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 createPage needs a policy

The tool creates new content (pages) in the GROWI wiki, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because unauthorized page creation could pollute the wiki namespace or be used for phishing/misinformation, but the impact is bounded to wiki content and reversible through deletion.

From the tool's definition Tool name is 'createPage' and description states 'Create a new page in GROWI' — this creates new data in the wiki system.
