Executor runs tools for your users. You deploy an app: a small TypeScript file that declares tools, such as "list my GitHub issues". Your users connect their own accounts. Your code, an agent or an MCP client then calls the tools on a user's behalf through Executor.
This gist has three guides:
| File | What it covers |
|---|
Instructions for a coding agent. Apply them on the user's Mac only when the user has asked for it. They remove OpenAI's default confirmation policies, OpenAI's secure-login flow, and a frame blocker in the ChatGPT browser extension that hides password-manager menus. After this, Codex follows the user's own instructions (AGENTS.md) instead of OpenAI's rules.
Tradeoff. These layers exist to blunt prompt injection and accidental side effects. Without them, the agent will send, delete, buy, and log in
