WHAT IT DOES

What insert_operator_at_selection does on tdmcp — TouchDesigner MCP server

AI agents use insert_operator_at_selection 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.

RISK

Why insert_operator_at_selection is rated Medium

This tool creates/modifies the TouchDesigner project by inserting operators, which is a reversible change (supported by rollback state). It does not execute arbitrary code, delete data, or cause financial impact. While it operates within a visual/media context, the core action is data modification within a project structure, making it Write rather than Execute.

From the tool's definition Tool description states it will 'insert one same-family operator' on a 'downstream edge' with 'explicit non-overlapping placement' and 'rollback state'. This is a create/modify operation that adds new elements to the TouchDesigner project structure.

RECOMMENDED RULE

The rule that runs insert_operator_at_selection 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 insert_operator_at_selection, this is the rule to start with:

insert_operator_at_selection Rate-limited

insert_operator_at_selection 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 insert_operator_at_selection

What does the insert_operator_at_selection tool do? +

Atomically insert one same-family operator on one deterministic downstream edge of the exactly selected/current TouchDesigner operator. Requires an exact editor-context compare-and-swap and an idempotency key; returns bounded before/after connector receipts, explicit non-overlapping placement and rollback state. Fan-out siblings and sibling inputs are preserved. Uses the authenticated structured bridge with ALLOW_EXEC=0; it never invokes raw Python, mouse-interactive placeOPs, or implicit pane selection. 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.

How do I enforce a policy on insert_operator_at_selection? +

Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for insert_operator_at_selection: 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.

What risk level is insert_operator_at_selection? +

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

Can I rate-limit insert_operator_at_selection? +

Yes. Add a rate_limit block to the insert_operator_at_selection 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 insert_operator_at_selection completely? +

Set action: deny in the PolicyLayer policy for insert_operator_at_selection. 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 insert_operator_at_selection? +

insert_operator_at_selection 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.
