How to connect a GitHub MCP with Codex (4 steps)
Blog post from Merge
Merge's platform facilitates seamless integration between Codex and GitHub by using the Merge Agent Handler, which connects Codex tasks to GitHub's API for more accurate and context-aware code generation. This connection allows Codex to access full issue threads, pull request comments, and source code directly from GitHub, ensuring comprehensive understanding and adherence to existing project conventions. The process involves installing and configuring the Merge CLI, authenticating with GitHub, and managing OAuth tokens securely to prevent unauthorized access. Merge's approach eliminates the need for personal access tokens in repositories and provides centralized auditing and access control, making it suitable for engineering teams that require both flexibility and security in managing AI-assisted development tasks.
