create_automation_lane
Build a per-parameter automation lane that records a live parameter sweep into a circular buffer over N bars, then loops the recording back into the parameter on a bar-phase clock. Two modes: record (sample the target param every cook into a ring buffer) or loop (read the buffer back via Lookup C...

What create_automation_lane does on tdmcp — TouchDesigner MCP server
AI agents use create_automation_lane to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.
Why create_automation_lane is rated Medium
This tool creates and configures a network of nodes (automation lane) within TouchDesigner and writes data into a circular buffer, binding it to parameters. It is a creative/write operation that constructs and modifies the project structure reversibly — it can be reconfigured by re-calling with different parameters. No code execution, deletion, or financial action is involved.
From the tool's definition Build a per-parameter automation lane that records a live parameter sweep into a circular buffer... Re-calling with the same name and a different mode flips the state without rebuilding the network.

The rule that runs create_automation_lane safely
PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_automation_lane, this is the rule to start with:
create_automation_lane 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.
The button opens the PolicyLayer dashboard: create your workspace, connect tdmcp — TouchDesigner MCP server, apply this rule, and every create_automation_lane call is checked against it from then on.
Questions about create_automation_lane
Build a per-parameter automation lane that records a live parameter sweep into a circular buffer over N bars, then loops the recording back into the parameter on a bar-phase clock. Two modes: record (sample the target param every cook into a ring buffer) or loop (read the buffer back via Lookup CHOP bound to the target param). Re-calling with the same name and a different mode flips the state without rebuilding the network. Uses Beat CHOP → Select CHOP (rampbar) → Lookup CHOP playback, with COMP storage tracking mode/write_head/armed state. Returns a summary plus a JSON block with container path, mode, samples count, target, and any warnings. It is categorised as a Write tool in the tdmcp — TouchDesigner MCP server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_automation_lane: 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 tdmcp — TouchDesigner MCP server. Nothing to install.
create_automation_lane 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 create_automation_lane 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_automation_lane. 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_automation_lane is provided by the tdmcp — TouchDesigner MCP server MCP server (@dpantani/tdmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
