The official CLI for Momentic Mobile. Build, run, and manage end-to-end tests for iOS and Android through natural language prompts.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is a first-party Momentic CLI that writes its own agent skills and MCP config only from user commands, with a TTY confirm on ordinary run, test, and app. There is no install-hook takeover, hidden exfiltration, or self-install chain, so the guarded agent-extension writes warrant a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs momentic-mobile run, test, or app in a TTY with a Momentic config present, or explicitly runs skills or install-mcp.
Impact
Project and user agent instruction and MCP files for this product can change. A saved Momentic API key is copied into that config only when the caller passes the opt-in flag.
Mechanism
After consent or an explicit command, the process removes and rewrites bundled skill trees and region markers in agent instruction files, or merges an MCP server entry into the selected client config.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json exposes only the momentic-mobile bin at bin/cli.js and declares no preinstall, install, or postinstall scripts and no runtime dependency on itself.
- On run, test, and app, a TTY session can prompt and then delete and rewrite bundled skill files plus agent instruction pointers under the project for Claude Code, Cursor, Codex, Copilot, and OpenCode.
- The skills command can install those same first-party files, skipping the prompt when --yes is set and falling back to detected agents.
- install-mcp is an explicit command that writes this CLI into detected coding-agent MCP configs and copies a saved API key only when --api-key or --with-api-key is passed.
Evidence against
- Skill setup from ordinary commands returns immediately without a TTY, when MOMENTIC_SKIP_SKILLS_PROMPT is set, or when the user declines the confirm prompt.
- No install lifecycle hook mutates agent config, and the API key is not written into MCP config by default.
