AI agents invoke keyboard_press to trigger actions in OODA Computer Control. 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.
Simulating keyboard input can trigger arbitrary system actions depending on the key combination pressed (e.g., Ctrl+Alt+Del, Ctrl+W, Alt+F4). The effect is entirely context-dependent and can cause unintended application behavior, data loss, or system-level operations, making this an Execute-category tool with high severity.

Documented attack patterns abuse exactly the kind of access keyboard_press gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OODA Computer Control, and nothing reaches the server without passing your rules. This is the rule we recommend for keyboard_press:
{
"version": "1",
"default": "deny",
"tools": {
"keyboard_press": {
"limits": [
{
"counter": "keyboard_press_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}keyboard_press 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.

Press a key with optional modifiers (ctrl, alt, shift). It is categorised as a Execute tool in the OODA Computer Control MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OODA Computer Control MCP server in PolicyLayer and add a rule for keyboard_press: 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 OODA Computer Control. Nothing to install.
keyboard_press 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 keyboard_press 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 keyboard_press. 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.
keyboard_press is provided by the OODA Computer Control MCP server (mnehmos/mnehmos.ooda.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OODA Computer Control, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
