WHAT IT DOES

What generate_experimental_diagram does on Notemd MCP Server

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

WHY IT NEEDS A POLICY

Why generate_experimental_diagram needs a policy

This tool generates diagram artifacts within the knowledge base. While diagrams are reversible (can be edited/deleted), the tool creates or modifies data within Markdown files. It does not execute arbitrary code or delete data, so Write is the appropriate category rather than Execute or Destructive.

From the tool's definition Tool generates diagram content, explicitly described as 'generate_diagram' functionality with 'legacy-mermaid compatibility mode'. The sibling tool 'generate_diagram' and context of 'Markdown files' indicate this creates or modifies file content.
