WHAT IT DOES

What reconfigure_basin does on S2 StreamStore MCP Server

AI agents use reconfigure_basin to create or update resources in S2 StreamStore MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your S2 StreamStore MCP Server environment.

WHY IT NEEDS A POLICY

Why reconfigure_basin needs a policy

Reconfiguring a basin changes its settings/configuration. This is a Write operation (update/modify) rather than Destructive since reconfiguration is typically reversible. However, severity is high because misconfiguring a basin could affect all streams within it and potentially disrupt data access or processing pipelines at scale.

From the tool's definition "Reconfigure a basin" — modifies configuration of a basin, which is a reversible write/update operation
