WHAT IT DOES

What ims_graph_create_pattern does on IMS MCP Server

AI agents use ims_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 ims_graph_create_pattern needs a policy

The 'create' prefix combined with graph-based sibling tools indicates this tool creates or adds data to the IMS graph structure. This is reversible (nodes can be deleted or modified), making it Write rather than Destructive. The empty description prevents higher confidence, but the naming pattern and server context strongly suggest data creation without deletion or financial impact.

From the tool's definition Tool name 'ims_graph_create_pattern' contains 'create', which indicates data creation. Sibling tools include 'graph_create_bug', 'graph_create_component', 'graph_create_decision', 'graph_create_feature', all Write-category operations.
