Codex

Codex can connect to a remote MCP server from its MCP configuration. Add https://mcp.atode.dev/mcp, select OAuth 2.1/PKCE when prompted, and finish the browser sign-in and consent flow. The client receives and refreshes its OAuth tokens for the connection.

Test the connection by asking Codex to list atode tools. Remove the server from the MCP configuration and revoke its OAuth grant when access is no longer needed.
