WHAT IT DOES

What select_option does on Playwright MCP Server

AI agents invoke select_option to trigger actions in Playwright MCP Server. 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 select_option is rated High

Based on the server context (Playwright browser automation) and sibling tools like 'click', 'check_checkbox', 'clear_text', 'evaluate', this tool almost certainly selects an option in a dropdown/select element — a browser interaction action. Empty description lowers confidence, but the pattern is consistent with Execute-class browser automation. Misuse could trigger unintended form submissions or UI state changes.

From the tool's definition Tool name 'select_option' on a Playwright browser automation server that enables 'webpage interaction, DOM manipulation'

RECOMMENDED RULE

The rule that runs select_option safely

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

select_option Rate-limited

select_option 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.
