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 inspected pi integration is session-scoped and leaves global and project pi configuration untouched, but it is package-owned agent MCP setup, which warrants a warning under the agent integration policy. The postinstall hook also installs a pinned Graphify runtime into a dedicated virtual environment; no concrete malicious behavior was established in the inspected excerpts.

Static reason

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

Trigger

A Jait gateway starts a pi-based ACP session that includes MCP servers.

Impact

The pi session can access Jait MCP tools; the inspected behavior does not establish an attack or broad agent configuration change.

Mechanism

The provider creates a session-specific config and wrapper, then passes the wrapper path through the pi command environment variable.

AI rationale

Evidence

dist/providers/pi-mcp-provision.jsdist/providers/acp-provider.jstemporary session directory

Decision evidence

public snapshot

AI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The install hook provisions a pinned Graphify runtime in a dedicated Python virtual environment.
For pi-based ACP sessions with MCP servers, the provider creates a temporary MCP config and wrapper to expose Jait's servers to pi.
The configuration behavior is limited to sessions and does not modify global or project pi configuration.

Evidence against

No inspected source showed credentials being sent to an unrelated recipient or another concrete attack chain.
