Safety Assessment

Playwright MCP is relatively safe when used with carefully defined allowed origins and restricted file access. Risks increase if unrestricted access is granted, potentially leading to unintended actions on web pages or unauthorized file access. Ensure proper configuration to mitigate these risks.

Operates on accessibility tree, avoiding pixel-based input.
Deterministic tool application reduces ambiguity.
Allows configuration of allowed/blocked origins to control browser requests.
File access can be restricted to workspace roots.

Can perform actions on web pages, potentially leading to unintended consequences.
If allowed-origins is set to '*', it can make requests to any origin.
If allow-unrestricted-file-access is enabled, it can access files outside workspace roots.
Improperly configured blocked-origins may not provide adequate protection.
