| Best for | - Teams developing games, levels, animation, or visual effects with Unreal Engine 5.
- Users who want AI to perform repetitive editor and content-production tasks.
- Users comfortable managing Unreal projects, plugins, and local development environments.
| - Engineering teams scaling AI coding agents while controlling spend
- Platform teams that need auditable, rollback-aware agent execution records
- Organizations using multiple agents (Claude, Codex, Gemini) under one governed flow
|
|---|
| Not for | - Projects that do not use Unreal Engine.
- Blueprint-only environments that cannot install a pre-built plugin or compile a code plugin.
- Public or remote exposure without appropriate network security configuration.
| - Developers who just want a simple code-completion helper without run governance
- Teams unwilling to accept local JSONL run records with HMAC signing
- Environments without a supported adapter (Claude/Codex/Gemini CLIs, direct provider, or verifier-only)
|
|---|
| Required permissions | - Access to and control of the specified Unreal project.
- Installation and execution of the MCP Automation Bridge plugin and required Unreal plugins.
- Some features require Python, Editor Scripting Utilities, Niagara, Gameplay Abilities, Smart Objects, or other plugins.
- Node.js 18 or later is required for the TypeScript Bridge.
| - Read/write access to the configured repo root (writable scope restrictable via --allow-path/--deny-path)
- Ability to invoke the chosen agent CLI (Claude/Codex/Gemini, etc.) and its underlying model account
- Local disk writes for run records, receipts, and share outputs (share/run-receipt., etc.)
- Execution of user-configured verifier commands (e.g. npm test)
|
|---|
| Risks and side effects | - The server can modify assets, actors, levels, project settings, and other game-development content.
- Enabling non-loopback addresses exposes the automation bridge to the local network; use trusted networks and enable capability-token authentication.
- Incorrect console commands, scripts, or automation actions can change project content or editor state.
- Pre-built plugin binaries are tied to specific Unreal Engine versions.
| - Verifier commands are executed; poorly chosen verifier commands carry security risk despite preflight policy checks
- Cost and token figures may be estimates (labeled with provenance) and should not be treated as settled accounting
- Receipt integrity must be verified before use as trustworthy evidence; missing rollback evidence is flagged as EVIDENCE_BOUNDARY
- Policy defaults come from martin.config.yaml and can be overridden by CLI flags; misconfiguration can loosen safety boundaries
