WHAT IT DOES

What select_page does on Chrome DevTools MCP

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

RISK

Why select_page is rated Medium

An AI agent can call select_page faster than any human can review: one bad instruction and it creates or modifies resources in Chrome DevTools MCP by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs select_page safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Chrome DevTools MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For select_page, this is the rule to start with:

select_page Rate-limited

select_page 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.
