MindExec local runtime and bridge CLI

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No confirmed malicious install-time attack surface is established. The package is a local AI bridge with high-risk user-invoked capabilities guarded by bridge tokens and local runtime setup.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Explicit CLI/runtime use via mindexec, mind-bridge, or node server.js; postinstall only grammar setup.

Impact

User-authorized local project automation can read/write project files, run configured agents, and call configured external services; no source evidence of stealth exfiltration or persistence.

Mechanism

local bridge server with user-invoked AI, remote-agent, filesystem, and network features

Rationale

Static inspection found dangerous primitives, but they are aligned with an explicit local AI bridge product and not activated by npm install except benign grammar copying. Because runtime copies Codex auth/config into a package-owned runtime and offers agent/file/shell capabilities, warn rather than block.

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Runtime includes Codex integration that creates ~/.mindexec/codex-runtime and copies ~/.codex/auth.json when user invokes AI features.
server.js exposes authenticated local bridge APIs for project file writes/removes and shell/Codex/remote-agent operations.
Network code contacts OpenAI/OpenRouter/Supabase/YouTube/search endpoints during user-facing features.

Evidence against

package.json postinstall only runs scripts/setup-tree-sitter-grammars.mjs; it copies fixed tree-sitter WASM files into package tree-sitter-grammars.
No install-time mutation of foreign AI-agent config found; Codex config/auth copying occurs in runtime helper codex-runtime.js, not postinstall.
launch-bridge.cjs starts local server.js for explicit CLI/bin use and opens localhost app; no hidden download or exfiltration path found in inspected entrypoints.
