Overview

Use this skill to manage Codex's own configuration and runtime setup. Start with MCP server management; expand with new capabilities as needed.

Core capabilities

1. MCP management

• Use when asked to add, remove, or update MCP servers or edit Codex MCP settings.
• Read references/mcp-management.md for CLI syntax and config options from the docs.
• Prefer the CLI for adding servers; edit ~/.codex/config.toml for fine-grained config.
• Remove a server by deleting its [mcp_servers.<server-name>] table or set enabled = false to disable.
• Confirm the active set via /mcp in the Codex TUI or by inspecting the config file.
