Level 7: Tool Operator — Use MCP, Browsers, and Connectors

Level 7 lets Codex use browsers, MCP, connectors, images, and document tools. It verifies real evidence that cannot be established from source code alone.

Typical Work

• Open a local page and check the rendered layout
• Read issue or PR state through a GitHub connector
• Compare a screenshot with the implementation
• Retrieve required information from a CMS or document tool

Permission Boundaries

Separate read and write access. Publication, sending, deletion, and other consequential operations should require approval. Define what sensitive information each tool may handle.

Next Level

When work can be divided into independent units, continue to Level 8: Parallel Orchestrator — Run Multiple Tasks in Parallel.
