Play a drum pattern using SuperCollider.
AI agents invoke create_drum_pattern to trigger actions in SuperCollider OSC 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.
This tool executes an external operation (audio playback via OSC in SuperCollider). It doesn't merely read or write data — it triggers real-time sound synthesis on an external system. Misuse could cause unwanted noise output or resource consumption on the audio system, warranting medium severity.

Documented attack patterns abuse exactly the kind of access create_drum_pattern gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SuperCollider OSC MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_drum_pattern:
{
"version": "1",
"default": "deny",
"tools": {
"create_drum_pattern": {
"limits": [
{
"counter": "create_drum_pattern_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}create_drum_pattern 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.
Free to start. No card required.
Play a drum pattern using SuperCollider. It is categorised as a Execute tool in the SuperCollider OSC MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the SuperCollider OSC MCP server in PolicyLayer and add a rule for create_drum_pattern: 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 SuperCollider OSC MCP. Nothing to install.
create_drum_pattern 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 create_drum_pattern 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 create_drum_pattern. 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.
create_drum_pattern is provided by the SuperCollider OSC MCP server (tok/supercollidermcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SuperCollider OSC MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
