What create_sidechain_pump does on Aos
AI agents invoke create_sidechain_pump to trigger actions in Aos. 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.
Why create_sidechain_pump is rated High
The tool appears to create and connect multiple TouchDesigner operators to set up a sidechain pump effect in one call. This spans Write (creating nodes) and Execute (triggering live visual/audio system changes). Since it operates on a live visual system and the description is nearly empty ('EXPERIMENTAL — One-call' is all we have), confidence is lowered.
From the tool's definition 'EXPERIMENTAL — One-call' and the name 'create_sidechain_pump' suggest triggering an audio-reactive sidechain pumping effect in TouchDesigner, creating nodes/operators and wiring them together
Attacks that exploit this kind of access
The rule that runs create_sidechain_pump safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_sidechain_pump, this is the rule to start with:
create_sidechain_pump 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every create_sidechain_pump call is checked against it from then on.
Questions about create_sidechain_pump
EXPERIMENTAL — One-call. It is categorised as a Execute tool in the Aos MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Aos MCP server in PolicyLayer and add a rule for create_sidechain_pump: 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 Aos. Nothing to install.
create_sidechain_pump 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_sidechain_pump 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_sidechain_pump. 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_sidechain_pump is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
