Check Codex client, transport, authentication and runtime before connecting GitHub MCP, Playwright MCP or Context7. Follow the official server guide.
First identify the task you want Codex to perform. GitHub MCP supplies repository tools, Playwright MCP supplies browser interaction, and Context7 supplies library documentation. Their connection requirements differ even though all three use MCP.
Open the card and confirm that it describes your Codex interface. The reviewed configurations here concern the CLI. A setup for another agent, or the presence of a plugin in a directory, is not a substitute for the server's Codex guide.
| Server | Reviewed approach | What to prepare |
|---|---|---|
| GitHub MCP Server | Remote HTTP configuration | GitHub authentication and repository scope |
| Playwright MCP | Local stdio configuration | Node.js and browser requirements |
| Context7 | Hosted documentation service | Its documented authentication method |
Read the current source linked from the card before copying commands. Check endpoint, launch requirements and account permissions. Keep credentials in the supported credential mechanism rather than shared source files.
Use the configuration described for the selected server and client. Complete authentication where required. Start a new session if the provider guide requires it, then inspect which tools are actually available. Installation and authorization are separate checks.
Use a representative repository, browser page or documentation lookup that you are allowed to access. Check the resource identity and result. If a connection succeeds but an action is unavailable, inspect the account scope, transport and server-specific troubleshooting before broadening permissions.
Codex, the service, API usage and local hosting can have separate charges. A documented connection does not establish a complete free setup. The catalog's checks concern documentation, not practical installations.
Compare the three Codex MCP options or the broader Codex plugins and servers before deciding.
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.
