WHEN AI AGENTS USE THIS TOOL

AI agents use resize_page to create or modify resources in Chrome DevTools. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON RESIZE_PAGE

Without a policy, an AI agent could call resize_page repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Chrome DevTools.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

FREQUENTLY ASKED QUESTIONS

What does the resize_page tool do?

Adjust viewport dimensions. It is categorised as a Write tool in the Chrome DevTools MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on resize_page?

Add a rule in your Intercept YAML policy under the tools section for resize_page. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Chrome DevTools MCP server.

What risk level is resize_page?

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

Can I rate-limit resize_page?

Yes. Add a rate_limit block to the resize_page rule in your Intercept 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 resize_page completely?

Set action: deny in the Intercept policy for resize_page. 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 resize_page?

resize_page is provided by the Chrome DevTools MCP server (ChromeDevTools/chrome-devtools-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
