WHAT IT DOES

What browser_close_page does on Mcp Captcha Solver

AI agents invoke browser_close_page to trigger actions in Mcp Captcha Solver. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why browser_close_page is rated High

Closing a browser session is an external operation that terminates a running process and may discard any unsaved state or in-progress work within that session. It is not purely destructive (no data is deleted) but it executes an action with real side effects on the browser environment.

RECOMMENDED RULE

The rule that runs browser_close_page safely

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

browser_close_page Rate-limited

browser_close_page stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
