td_connect · Td MCP: Risk & Policy

WHAT IT DOES

What td_connect does on Td

AI agents use td_connect to create or update resources in Td — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Td environment.

WHY IT NEEDS A POLICY

Why td_connect needs a policy

Connecting operators in TouchDesigner creates a data flow relationship between nodes. This is a modification operation that changes the project state reversibly (connections can be disconnected). It does not execute code, delete data permanently, or move money. It fits Write category as it creates/modifies project structure.

From the tool's definition Tool description states 'Connect two operators' - this modifies the TouchDesigner node graph by creating a connection between operators, which is a reversible structural change to the project.

Verdict

td_connect Rate-limited

td_connect 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.

FAQ

Questions about td_connect

What does the td_connect tool do? +

Connect two operators. It is categorised as a Write tool in the Td MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on td_connect? +

Register the Td MCP server in PolicyLayer and add a rule for td_connect: 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 Td. Nothing to install.

What risk level is td_connect? +

td_connect is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit td_connect? +

Yes. Add a rate_limit block to the td_connect 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.

How do I block td_connect completely? +

Set action: deny in the PolicyLayer policy for td_connect. 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.

What MCP server provides td_connect? +

td_connect is provided by the Td MCP server (tai5863/td-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
