MindExec local runtime and bridge CLI

AI Security Review

scanned 15h ago · by lpm-firewall-ai

No confirmed malicious install-time behavior was found. Residual risk is a high-capability user-invoked local/remote AI bridge with shell, filesystem, MCP, Codex, browser, and remote-agent controls.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm postinstall copies grammars; user runs mindexec/mind-bridge or server.js to activate bridge and RemoteHub.

Impact

If exposed or misconfigured, authorized callers can execute commands, modify workspace files, call MCP tools, run Codex, proxy configured services, and control remote agents.

Mechanism

user-invoked local AI bridge and remote agent manager

Attack narrative

The scanner's critical labels are explained by a package-aligned local bridge: after explicit startup it exposes shell, filesystem, browser, MCP, Codex, and remote-agent APIs. The only lifecycle hook is grammar setup inside the package, not agent-control hijacking or persistence. The broad runtime capability and default externally bound RemoteHub justify a warning, but source inspection did not show unconsented install-time mutation, credential theft, or covert exfiltration.

Rationale

Static source inspection supports a powerful AI/remote bridge with real security exposure when run, but not malicious package behavior or unconsented lifecycle control-surface mutation. Treat as warn-worthy dangerous capability rather than publish-block malware.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for block

server.js exposes protected local APIs for shell execution, file write/delete, MCP calls, and Codex runs when user starts the bridge.
remote-hub.js starts a TCP RemoteHub on 0.0.0.0:5199 by default with pair-token authentication for remote agents.
codex-runtime.js can create ~/.mindexec/codex-runtime and copy Codex auth.json into that isolated runtime home for agent runs.
server.js fetches model/catalog or service data from openrouter.ai, api.imagerouter.io, Supabase URLs, YouTube, and configured MCP/server URLs at runtime.

Evidence against

package.json postinstall only runs scripts/setup-tree-sitter-grammars.mjs, which copies tree-sitter WASM grammars into tree-sitter-grammars/.
No install-time writes to foreign AI agent control files such as .mcp.json, CLAUDE.md, Cursor/Codex settings, or shell startup files were found.
launch-bridge.cjs is user-invoked CLI startup; it spawns server.js, sets WORKSPACE_PATH, and optionally opens localhost UI.
server.js binds the main bridge HTTP server to 127.0.0.1 and requires X-Bridge-Token for protected routes by default.
Workspace file APIs validate paths under the workspace or opened project root before read/write/delete.
No concrete credential harvesting or unsolicited exfiltration path was found in inspected source.
