Questions

What tools does Frame0 expose?

28 in total: 11 read-only, 15 that write, and 2 that can delete or overwrite (delete_page, delete_shape). Every one is listed on this page with its risk.

Is Frame0 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: 2 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Frame0 need?

No credential environment variables were found in its source, so it appears to need none.

How does Frame0 run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as frame0-mcp-server at 0.12.0.

How current is this page?

The grade is for one exact copy of the source (c2675421cdaf), read on 2026-10-07. The repository is watched and re-audited when it changes.
