AI agents invoke dance to trigger actions in Reachy Mini MCP Server. 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.
Based on the server description mentioning 'choreographed dances' and sibling tools like move_head and play_emotion, 'dance' likely triggers physical robot movement sequences. This is an Execute-category action as it triggers external physical operations on a robot.
From the tool's definition Tool name 'dance' on a server that controls physical Reachy Mini robots with 'choreographed dances' mentioned in server description; description is empty.
Documented attack patterns abuse exactly the kind of access dance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Reachy Mini MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for dance:
{
"version": "1",
"default": "deny",
"tools": {
"dance": {
"limits": [
{
"counter": "dance_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}dance 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.

dance. It is categorised as a Execute tool in the Reachy Mini MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Reachy Mini MCP Server MCP server in PolicyLayer and add a rule for dance: 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 Server. Nothing to install.
dance 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 dance 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 dance. 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.
dance is provided by the Reachy Mini MCP Server MCP server (pixelml/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 Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
