Questions
What is the appscreen-studio MCP server?
Modern web studio for generating Google Play Store screenshots, realistic phone mockups, multilingual localizations, and feature graphics.
What tools does appscreen-studio expose?
31 in total: 23 read-only, 7 that write, and 1 that can delete or overwrite (remove_screen). Every one is listed on this page with its risk.
Is appscreen-studio safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does appscreen-studio need?
No credential environment variables were found in its source, so it appears to need none.
How current is this page?
The grade is for one exact copy of the source (fe8f80699724), read on 2026-10-10. The repository is watched and re-audited when it changes.
