Perch AI command-line interface

AI Security Review

scanned 3d ago · by lpm-firewall-ai

No confirmed malicious attack surface. The package is a user-invoked AI CLI with package-aligned Perch API, OAuth, local state, and optional local-tool functionality.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs the perch command and chooses its interactive commands or options.

Impact

No unconsented install-time execution, credential exfiltration, clipboard hijack, or foreign-package modification was established.

Mechanism

User-invoked Perch CLI and agent workflow.

Rationale

Direct inspection shows the flagged primitives are attributable to the CLI's documented agent, OAuth, telemetry, and clipboard-paste features. No concrete malicious chain was found.

Evidence

package.jsonbin/perchdist/perch.mjsREADME.md

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no lifecycle scripts; it only exposes the perch bin.
bin/perch only imports dist/perch.mjs when the user runs perch.
Clipboard code implements browser paste/write verification, not wallet-address replacement.
Network calls target Perch app APIs and documented OAuth/session flows.
Shell/file tooling is a visible Perch feature with local-tools and permission controls.
No crypto-address matcher, foreign package overwrite, or install-time mutation was found.
