WHAT IT DOES

What cdp.dom.setAttribute does on Pixi Inspector

AI agents call cdp.dom.setAttribute as a supporting operation in Pixi Inspector workflows.

Parameter	Type	Required	Description
`name`	string	Yes	Attribute name.
`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`	string	Yes	Attribute value.
`nodeId`	integer	—	CDP nodeId.
`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,
`selector`	string	—	CSS selector (alternative).

Parameters from the server's own tool schema.

RISK

Why cdp.dom.setAttribute is rated Low

Without any rule in front of it, every call an agent makes to cdp.dom.setAttribute happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

RECOMMENDED RULE

The rule that runs cdp.dom.setAttribute 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 cdp.dom.setAttribute, this is the rule to start with:

cdp.dom.setAttribute Rate-limited

cdp.dom.setAttribute gets a rate cap, and everything else on the server is denied unless you say otherwise.

Questions about cdp.dom.setAttribute

What does the cdp.dom.setAttribute tool do? +

What parameters does cdp.dom.setAttribute accept? +

cdp.dom.setAttribute accepts 7 parameters: name, tabId, value, nodeId, target, frameId, selector. Required: name, value. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on cdp.dom.setAttribute? +

Register the Pixi Inspector MCP server in PolicyLayer and add a rule for cdp.dom.setAttribute: 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 Pixi Inspector. Nothing to install.

How do I block cdp.dom.setAttribute completely? +
