WHY IT NEEDS A POLICY

Why create_page_summary needs a policy

The tool appears to create or generate summary content (a new artifact), which is a reversible write operation. Without explicit description, confidence is moderate. If it merely retrieves and reformats existing summaries, it would be Read; if it writes summary content back to the wiki, it is Write. Given the server's stated content management scope and the tool name, Write is the most likely category.

From the tool's definition Tool name 'create_page_summary' indicates creation of new content. Server description states the MCP server enables 'page creation, searching, and updating' operations.
