pixi.node.setProperty
Sets a single editable property on a node (e.g. x, alpha, visible). The value must have the property's type (as pixi.node.getProperties returns it): a read-only key (e.g. classesList) or a wrongly-typed value fails with BAD_PARAMS and a destroyed node with NODE_GONE; nothing changes on failure.

What pixi.node.setProperty does on Pixi Inspector
AI agents call pixi.node.setProperty to retrieve information from Pixi Inspector without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
id | string | Yes | Stable node id from the tree |
key | string | Yes | Property key, e.g. 'x', 'alpha', 'visible' |
tabId | integer | — | Legacy: a bare tab id, resolved inside the browser this session is already working with. Prefer `target`, which is unambiguous across browsers. |
value | number | string | boolean | Yes | New value (number | string | boolean) |
target | string | — | Drive a specific tab: a target id like "b7a3c1#487" from status/use_target/CHOOSE_TARGET. Omit to use this session's chosen tab (or the only available one). Pas |
frameId | integer | — | Escape hatch: drive a specific FRAME of the tab (0 is the top frame). Normally unnecessary — the extension picks the frame running the game (canvas owner first, |

Why pixi.node.setProperty is rated Low
Even though pixi.node.setProperty only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs pixi.node.setProperty safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pixi Inspector, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pixi.node.setProperty, this is the rule to start with:
pixi.node.setProperty is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Pixi Inspector, apply this rule, and every pixi.node.setProperty call is checked against it from then on.
