WHAT IT DOES

What graph_create_pattern does on IMS MCP Server

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

WHY IT NEEDS A POLICY

Why graph_create_pattern needs a policy

The tool name strongly suggests creating and storing a new pattern record in the IMS graph system, which is a reversible Write operation. Without a description, confidence is moderately lowered, but the naming convention and sibling context support Write categorization.

From the tool's definition Tool name 'graph_create_pattern' indicates creation of a new entity (pattern) in a graph structure. No description provided, but the 'create_' prefix aligns with write operations.
