WHAT IT DOES

What hotkey does on Mcp Control Plane

AI agents invoke hotkey to trigger actions in Mcp Control Plane. 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.

RISK

Why hotkey is rated High

This tool triggers keyboard input actions on a live system. Hotkeys can execute arbitrary system commands, close applications, delete data, or perform sensitive OS-level operations depending on the key combination passed. An AI agent could misuse this to trigger destructive shortcuts (e.g., Alt+F4, Ctrl+Z, Win+D) or interact with privileged system dialogs, making it a high-severity Execute tool.

From the tool's definition Press a key combination, for example ['ctrl', 'l']

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hotkey safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hotkey, this is the rule to start with:

hotkey Rate-limited

hotkey 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.

    }
  }

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every hotkey call is checked against it from then on.

FAQ

Questions about hotkey

What does the hotkey tool do? +

Press a key combination, for example ['ctrl', 'l']. It is categorised as a Execute tool in the Mcp Control Plane MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on hotkey? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for hotkey: 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 Mcp Control Plane. Nothing to install.

What risk level is hotkey? +

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

Can I rate-limit hotkey? +

Yes. Add a rate_limit block to the hotkey 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.

How do I block hotkey completely? +

Set action: deny in the PolicyLayer policy for hotkey. 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.

What MCP server provides hotkey? +

hotkey is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
