Jait AI gateway — local-first AI coding agent with terminal, filesystem, and browser control

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The postinstall hook conditionally installs a separately managed Python package, adding supply-chain risk beyond the declared npm dependencies. Source inspection does not establish a concrete attack, so this warrants a warning rather than a block.

Static reason

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

Trigger

Installing the npm package when the Graphify runtime is absent and no custom Graphify command is configured.

Impact

The installation runs package-manager behavior during npm postinstall, expanding the supply-chain surface. Inspected source does not establish malicious payload behavior.

Mechanism

The hook invokes the bundled runtime manager, which creates a Python virtual environment and runs pip to install a pinned Graphify package.

AI rationale

Evidence

package.jsonbin/install-runtime.mjsdist/services/code-graph/graphify-runtime.jsJait state directory runtime/graphify

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs a package installer that imports the Graphify runtime manager.
When the managed runtime is missing, that manager creates a virtual environment and invokes pip to install a pinned package during npm installation.
The pi integration provisions MCP configuration per agent session and supplies it to the pi process.

Evidence against

The Graphify installation is placed under Jait’s state directory and pins the package version.
The pi integration is limited to pi-based providers and session-supplied MCP servers.
Browser search uses provider API keys for requests that pass through URL validation.
