reload_servers · SuperMCP Server MCP: Risk & Policy

WHAT IT DOES

What reload_servers does on SuperMCP Server

AI agents invoke reload_servers to trigger actions in SuperMCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why reload_servers needs a policy

This tool performs an active system operation: reloading configuration from a persistent store and reconstructing the in-memory registry. It is not a simple read (it modifies runtime state) nor a write (it doesn't persist new data), but rather executes an administrative action that reinitializes the orchestration layer.

From the tool's definition 'Reload servers from the registry and rebuild the in-memory registry' — triggers a rebuild/reinitialization operation on the in-memory server registry

reload_servers Rate-limited

reload_servers stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
