Connect Codex

Updated 2026-10-17

The Codex CLI and the IDE extension read the same config.toml. Use --url for hosted, npx for local.

Steps

  1. Run one of the commands. Codex writes the configuration to ~/.codex/config.toml.
  2. To edit by hand, add a [mcp_servers.thefaceanalysis] table to that file. For a per-project setup, put the table in .codex/config.toml at the root of a trusted project.
  3. Restart Codex and try the check prompt below.

Configuration

Hosted (recommended)
codex mcp add thefaceanalysis --url https://mcp.thefaceanalysis.com/mcp
Local (npx)
codex mcp add thefaceanalysis -- npx -y thefaceanalysis-mcp
config.toml (hosted)
[mcp_servers.thefaceanalysis]
url = "https://mcp.thefaceanalysis.com/mcp"
config.toml (local)
[mcp_servers.thefaceanalysis]
command = "npx"
args = ["-y", "thefaceanalysis-mcp"]

Check it works

Ask: “Using The Face Analysis, what is the median fWHR across your 102 reference faces?” The answer should be 1.78.
