What upgrade_ap_firmware does on Ikuai
AI agents invoke upgrade_ap_firmware 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 upgrade_ap_firmware is rated High
Upgrading firmware and rebooting an AP is an irreversible external operation with significant blast radius (network disruption, potential bricking), but it is not purely destructive data deletion. It is best classified as Execute since it triggers an external hardware operation with side effects dependent on arguments. Severity is high because misuse could cause network outages or render APs inoperable.
From the tool's definition 升级 AP 固件 ⚠️ AP 会重启 — triggers a firmware upgrade and forced reboot of the access point

The rule that runs upgrade_ap_firmware 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 upgrade_ap_firmware, this is the rule to start with:
upgrade_ap_firmware 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 upgrade_ap_firmware call is checked against it from then on.
Questions about upgrade_ap_firmware
升级 AP 固件 ⚠️ AP 会重启. It is categorised as a Execute tool in the Ikuai MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ikuai MCP server in PolicyLayer and add a rule for upgrade_ap_firmware: 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.
upgrade_ap_firmware 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 upgrade_ap_firmware 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.
Set action: deny in the PolicyLayer policy for upgrade_ap_firmware. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
upgrade_ap_firmware is provided by the Ikuai MCP server (gxxHuang/ikuai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
