Toggle bypass state of the currently selected device
AI agents use toggle_device_bypass to create or update resources in Bitwig MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bitwig MCP Server environment.
Toggling a device's bypass state modifies a reversible setting in Bitwig Studio (enabling/disabling a device effect). This is a reversible write operation with low blast radius — it only affects audio processing for the selected device and can easily be undone.

Documented attack patterns abuse exactly the kind of access toggle_device_bypass gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Bitwig MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for toggle_device_bypass:
{
"version": "1",
"default": "deny",
"tools": {
"toggle_device_bypass": {
"limits": [
{
"counter": "toggle_device_bypass_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}toggle_device_bypass stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Toggle bypass state of the currently selected device. It is categorised as a Write tool in the Bitwig MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Bitwig MCP Server MCP server in PolicyLayer and add a rule for toggle_device_bypass: 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 Bitwig MCP Server. Nothing to install.
toggle_device_bypass is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the toggle_device_bypass 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 toggle_device_bypass. 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.
toggle_device_bypass is provided by the Bitwig MCP Server MCP server (wemodulate/bitwig-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
