Add MCP Server to Codex

The elmah.io MCP Server can be integrated in Codex using the CLI.

Note

This configuration is shared between Codex CLI, the Codex IDE extension, and the ChatGPT desktop app's Codex surface. Registering the server once makes it available in all three.

  • Open a terminal and run the following command to register the elmah.io MCP server in your local Codex configuration:

codex mcp add elmahio --url https://mcp.elmah.io/mcp --oauth-client-id codex

  • Run the following command to start authentication:

codex mcp login elmahio

  • Follow the OAuth flow to sign in with your elmah.io account.
  • Run the following to confirm the server is connected:

codex mcp list

  • You should see elmahio listed as connected.
