Is Grok Faf safe and trustworthy?

tashan scores Grok Faf on public evidence — tashan score 49.0/100, it is currently active, note: a single primary maintainer (bus-factor risk), no known advisories against the current release, it runs a script at install time. Audit scope: OSV advisories, install-time scripts, build provenance and declared permission surface. We do not review source code or execute the capability.

How do I install Grok Faf?

In Claude Code: run `claude mcp add grok-faf -- npx -y grok-faf-mcp`. In Cursor / Claude Desktop, add it to mcp.json / claude_desktop_config.json.

Security audit

Every finding is shown in full — which advisory, the version that fixes it, and the exact command run at install time. Nothing in this audit is behind a licence.

No known advisoriesclearchecked against OSV for 1.10.0 — this package, not its dependency tree

Runs a script at install timecodenode scripts/postinstall.js

No access inferred from declared dependenciesnothing it depends on reaches files, shell or network. This reads declarations only — built-in APIs are invisible to it, so absence of a declaration is not absence of access

No build provenanceno attestation — the published artifact cannot be traced to its source
