reload_config · Mcpcute MCP: Risk & Policy

WHAT IT DOES

What reload_config does on Mcpcute

AI agents invoke reload_config to trigger actions in Mcpcute. 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_config needs a policy

This tool triggers an external operation — reloading the application configuration from disk — which causes the running system to pick up potentially new or changed MCP server definitions. It is not a simple read (it changes runtime state), not a write to persistent storage, and not destructive.

From the tool's definition 'Reload the mcpcute configuration file from disk. Use this after updating the config file to pick up changes like new MCP servers or updated versions.'

Verdict

reload_config Rate-limited

reload_config 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.

What risk level is reload_config? +

reload_config is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit reload_config? +
