WHAT IT DOES

What add_edge does on 247afk Block Editor MCP Server

AI agents use add_edge to create or update resources in 247afk Block Editor MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 247afk Block Editor MCP Server environment.

WHY IT NEEDS A POLICY

Why add_edge needs a policy

This tool creates new connections between nodes in a visual script editor, which is a reversible modification of script structure. It does not execute code, delete data irreversibly, or involve financial operations. The modification is live but can be undone (evidenced by the existence of remove_edge). Classified as Write rather than Execute because it manipulates the script graph itself rather than running it.

From the tool's definition Tool description states 'Connect two node ports with an edge' which modifies the script structure. Server description emphasizes 'live manipulation of block editor content' and 'edit 247afk scripts'.
