AI agents invoke look to trigger actions in Reachy Mini MCP. 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.
Given the server context (Reachy Mini robot control with vision capabilities) and sibling tools like 'snap' and 'show', 'look' most likely commands the robot to physically orient its head/camera toward a target, constituting an Execute-level action (triggering external physical operation). The description is empty, which reduces confidence.
From the tool's definition Tool name 'look' on a robot control server with sibling tools including 'snap' (camera), 'show' (display), 'listen' (audio) — likely triggers physical head/camera movement or gaze direction on the Reachy Mini robot.
Documented attack patterns abuse exactly the kind of access look gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Reachy Mini MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for look:
{
"version": "1",
"default": "deny",
"tools": {
"look": {
"limits": [
{
"counter": "look_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}look 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.

look. It is categorised as a Execute tool in the Reachy Mini MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Reachy Mini MCP server in PolicyLayer and add a rule for look: 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 Reachy Mini MCP. Nothing to install.
look 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 look 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 look. 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.
look is provided by the Reachy Mini MCP server (jackccrawford/reachy-mini-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Reachy Mini MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
