MCP servers for Codex

§1Where Codex reads MCP config

By default ~/.codex/config.toml; you can also scope servers to a trusted project with .codex/config.toml. Each server is a [mcp_servers.<name>] table. Codex supports stdio servers and Streamable HTTP servers (bearer token or OAuth).

codex mcp add context7 -- npx -y @upstash/context7-mcp
codex mcp list
codex mcp login <server-name>   # for OAuth servers

[mcp_servers.context7]
command = "npx"
args = ["-y", "@upstash/context7-mcp"]

[mcp_servers.figma]
url = "https://mcp.figma.com/mcp"

Useful options: enabled_tools / disabled_tools to limit what a server exposes, default_tools_approval_mode (auto, prompt, writes, approve), and startup_timeout_sec (default 10) / tool_timeout_sec (default 60).

§3FAQ

Where is the Codex MCP config?

~/.codex/config.toml by default, or .codex/config.toml in a trusted project. Each server is a [mcp_servers.<name>] table.

Does Codex support remote MCP servers?

Yes, Streamable HTTP servers with a url, using a bearer token, OAuth (run codex mcp login <name>), or static headers.

Can I restrict which tools a server exposes to Codex?

Yes. enabled_tools is an allow list and disabled_tools is a deny list applied after it; default_tools_approval_mode controls prompting.
