Claude Code logging, visualization, and management toolkit — launch a web viewer alongside Claude Code with full request/response tracing, proxy, and mobile support

AI Security Review

scanned 11d ago · by lpm-firewall-ai

No confirmed malicious attack surface was found. The package is a Claude Code viewer/proxy that can modify Claude hooks, shell rc files, local logs, and workspace/IM skill files when the user runs its CLI or UI features.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs ccv, ccv -logger, ccv --im, or uses local viewer APIs

Impact

Package-aligned tracing and management of Claude sessions; no install-time persistence or credential exfiltration confirmed

Mechanism

user-invoked Claude Code proxy, hook registration, and local skill/log management

Rationale

Static inspection shows sensitive primitives, but they are consistent with the package's advertised Claude Code viewer/proxy role and are user-invoked rather than lifecycle-triggered. I found no unconsented install-time agent control hijack, hardcoded exfiltration, destructive behavior, or remote payload execution.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no install/postinstall hook; only prepublishOnly build is publisher-side.
cli.js shell and Claude hook writes are reached by explicit ccv commands, not npm install/import.
server/lib/ensure-hooks.js writes cc-viewer-managed guarded hooks to Claude settings only for CCVIEWER_PORT sessions.
server/proxy.js forwards Claude API traffic to configured Anthropic/custom base URL for local tracing, not a hardcoded exfil endpoint.
server/interceptor.js masks x-api-key/authorization before log writes; cached auth is in-process for package features.
server/routes/skills.js upload/import validates names, blocks symlinks/path escape, and writes only selected skills roots.
