@cat-factory/server@0.66.4

Runtime-neutral HTTP layer for the Agent Architecture Board: the Hono controllers, middleware (auth/authz/CORS/error), request helpers and the gateway seams shared by every deployment facade (Cloudflare Worker, Node service).

AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established by source inspection. The package is an HTTP/server library with user-invoked controllers and configured upstream integrations.

Static reason

One or more suspicious static signals were detected.

Trigger

Runtime HTTP requests to exported Hono controllers in a configured Cat Factory deployment.

Impact

No unconsented install-time execution, credential harvesting, exfiltration, persistence, or destructive behavior identified.

Mechanism

Package-aligned server routing, OAuth/API proxying, and GitHub/LLM/web-search integrations.

Rationale

Scanner findings map to expected server functionality: route handlers, OAuth/API fetches, and crypto declarations, with no lifecycle hooks or covert execution path. No source-grounded malicious behavior was found.

Decision evidence

public snapshot

AI called this Clean at 92.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no install/preinstall/postinstall/prepare hooks; main is dist/index.js and package files are limited to dist.
dist/index.js is a re-export surface; no import-time execution beyond module exports observed.
dist/crypto/encoding.d.ts only documents PEM/PKCS8 decoding APIs; no embedded private key or secret value.
dist/modules/tasks/TaskSourceController.js defines Hono task/Linear OAuth routes invoked by HTTP requests, not dynamic require or install-time behavior.
Network use is package-aligned: OAuth, GitHub API, LLM proxy, and web search upstreams with configured credentials.
rg found no child_process, eval/new Function, filesystem writes, lifecycle scripts, or AI-agent control-surface writes.
