AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection confirms a guarded global-install setup that can modify detected AI client homes with Vibe-owned surfaces. This warrants a warning under the agent integration policy, but the inspected behavior does not establish malicious activity.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Installing the package globally through npm, unless VIBE_SKIP_SETUP is set.

Impact

Agent home configuration and plugin files may be created or updated as part of global installation.

Mechanism

The postinstall script imports setupGlobal, which installs configured surfaces for detected client homes; plugin setup also assembles files and registers a marketplace.

AI rationale

Evidence

package.jsonscripts/postinstall.jsdist/install/global.jsdist/install/plugin.jsdist/install/register.js

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json defines a postinstall script that runs scripts/postinstall.js.
The postinstall setup runs only for global installs and can be skipped with VIBE_SKIP_SETUP; it imports and calls setupGlobal.
setupGlobal installs surfaces for detected client homes, and installPlugin assembles and registers the package's plugin.
register.js reads the Claude plugin's installed version and marketplace configuration.

Evidence against

The inspected GitHub client sends authenticated requests to api.github.com, its configured GitHub API host.
The check runner executes scenario commands in the project root, consistent with the package's verification harness.

3 * vibe for the Claude desktop app — an MCP Bundle server that is nothing but a cable to the

5 * install time (VIBE_PROJECT_DIR) and returns the JSON. The verdict stays in the CLI; this

6 * surface is for the interview, the approval, the judgement and the handoff — not for writing code.

8 * MCP over stdio is newline-delimited JSON-RPC 2.0. Three methods matter here: initialize,

9 * tools/list, tools/call. No SDK: the protocol subset is small and the bundle stays dependency-free.
