set_configure · Scouter MCP: Risk & Policy

WHAT IT DOES

What set_configure does on Scouter

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

WHY IT NEEDS A POLICY

Why set_configure needs a policy

This tool creates or modifies data reversibly by updating configuration settings. While not destructive (changes can typically be reverted), it goes beyond read-only queries. The high severity reflects that misconfigured APM servers or agents could degrade monitoring visibility, trigger false alerts, or impact application performance tracking across the entire monitored system.

From the tool's definition 'Save server or agent configuration' indicates the tool modifies configuration settings. The description explicitly states it saves/persists configuration changes to server or agent targets.

Verdict

set_configure Rate-limited

set_configure stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
