pause_all · Syncthing MCP Server MCP: Risk & Policy

WHAT IT DOES

What pause_all does on Syncthing MCP Server

AI agents invoke pause_all to trigger actions in Syncthing MCP 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 pause_all needs a policy

This tool triggers an external operation that stops all file synchronization across the entire Syncthing instance. While not permanently destructive, pausing all syncing can have significant operational impact (data not syncing, potential for divergence between nodes) and affects the entire instance rather than a scoped subset.

pause_all Rate-limited

pause_all 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.
