Safety Assessment

This server offers useful browser automation but carries moderate risk. The ability to navigate to any URL and execute JavaScript introduces potential for malicious activity. Exercise caution when using Playwright tools with untrusted URLs or content. The note storage system itself poses a lower risk, but access should still be controlled.

Note storage is resource-based with a custom URI scheme.
Prompts are limited to summarizing existing notes.
Playwright actions are confined to the browser context.
No direct filesystem access.

Playwright tools can navigate to arbitrary URLs.
JavaScript execution is possible via `playwright_evaluate`.
No explicit input sanitization mentioned for Playwright actions.
Potential for unintended data exposure through screenshots or HTML content extraction.
Lack of RBAC controls on note access.
