MindExec local runtime and bridge CLI

AI Security Review

scanned 14h ago · by lpm-firewall-ai

No confirmed malicious attack surface. The package is a local AI/workspace bridge with dangerous user-invoked capabilities guarded by a local token, while install-time behavior is limited to packaged grammar setup.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install runs postinstall grammar setup; user runs mindexec to start local bridge

Impact

User-authorized local automation can read/write workspace files and run commands; no unconsented lifecycle hijack or exfiltration confirmed.

Mechanism

local bridge with authenticated file/shell/agent APIs

Rationale

Static inspection shows high-risk local automation features, but they are package-aligned, user-invoked, token-protected, and not delivered via install-time mutation of foreign AI-agent control surfaces. The postinstall hook only prepares packaged tree-sitter grammar files, so the scanner's execution/network/env findings are noisy for maliciousness.

Decision evidence

public snapshot

AI called this Clean at 82.0% confidence as Benign with low false-positive risk.

Evidence for block

server.js exposes local file, shell, MCP, Codex, browser, and remote-agent APIs when the bridge is explicitly run.
codex-runtime.js can create an isolated Codex home under ~/.mindexec/codex-runtime and spawn codex for requested runs.
remote-hub.js defaults a remote hub host constant to 0.0.0.0, but runtime bridge listens locally.

Evidence against

package.json postinstall only runs scripts/setup-tree-sitter-grammars.mjs to copy packaged tree-sitter WASM files into tree-sitter-grammars/.
launch-bridge.cjs is a user-invoked CLI that starts server.js and opens http://localhost:5167/mindcanvas.
server.js protects dangerous bridge routes with X-Bridge-Token by default and listens on 127.0.0.1.
No install-time writes to Claude/Codex/Cursor/MCP foreign control surfaces found.
Network endpoints are product-aligned: localhost bridge, Supabase, OpenAI/OpenRouter, YouTube/search, and user-supplied MCP/proxy URLs.
No credential harvesting or exfiltration path beyond configured product auth/session flows was confirmed.
