What scan_surrounding_channels does on Ikuai
AI agents invoke scan_surrounding_channels to trigger actions in Ikuai. 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 scan_surrounding_channels is rated High
This tool triggers an active scan of surrounding wireless channels on the iKuai router. It executes a real-time hardware/firmware operation rather than simply reading cached data. The blast radius is medium: misuse could disrupt wireless performance or interfere with connected clients during scanning, but it does not delete data or move money.
From the tool's definition 扫描周边信道 — 'scan' implies actively triggering a wireless channel scan operation on the router

The rule that runs scan_surrounding_channels safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ikuai, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scan_surrounding_channels, this is the rule to start with:
scan_surrounding_channels 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Ikuai, apply this rule, and every scan_surrounding_channels call is checked against it from then on.

Register the Ikuai MCP server in PolicyLayer and add a rule for scan_surrounding_channels: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ikuai. Nothing to install.
scan_surrounding_channels is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the scan_surrounding_channels rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
