Compare three documented Codex CLI MCP setups for repositories, browsers and library references. Check authentication, runtime and client-specific guides.
Choose GitHub MCP for repository workflows, Playwright MCP for browser interaction or Context7 for library documentation. These three servers have reviewed Codex-specific setup sources. They supply different tools rather than three versions of the same capability.
| Server | Task | Setup to inspect |
|---|---|---|
| GitHub MCP Server | Repository operations | Remote HTTP and GitHub authorization |
| Playwright MCP | Browser interaction | Local stdio, Node.js and browser |
| Context7 | Library documentation | Hosted connection and authentication |
The selection concerns Codex CLI. Inspect current configuration and permissions in the official source before using it in another surface. For GitHub, confirm repository scope; for Playwright, confirm the local runtime; for Context7, confirm service authentication and limits.
Follow the Codex MCP setup checklist and validate a small representative task. Documentation does not establish a practical installation test or a complete free cost model. The broader Codex section also covers separately listed plugin connections.
Retrieve current library documentation for a coding workflow.
Authentication and rate limits depend on the selected setup; verify the current service plan before relying on sustained usage.
Connect an assistant to GitHub repository, issue and pull-request workflows.
Grant only the GitHub permissions your workflow needs; host authentication and repository access remain separate requirements.
Let an MCP client inspect and operate web pages with Playwright.
Requires a supported Node.js and browser environment; browser automation access needs deliberate permission controls.
