WHY IT NEEDS A POLICY

Why create_wires needs a policy

Based on the server's documented capability to manage knowledge graphs and RDF operations, 'create_wires' most likely creates new connections or edges within a graph structure. This is a Write operation (reversible creation of data structures). Severity is medium because misuse could corrupt graph relationships, but the operation is theoretically reversible via deletion.

From the tool's definition Tool name 'create_wires' is listed among tools for 'managing Mnemosyne knowledge graphs' (per server description). The naming pattern matches sibling tools like 'create_graph' and 'create_folder', all supporting graph/data creation.
