Codex

The Codex CLI reads MCP servers from ~/.codex/config.toml and supports Streamable HTTP servers with custom headers.

Automatic

Manual

Add to ~/.codex/config.toml:

[mcp_servers.justclaw-it]
url = "https://justclaw.it.com/mcp"
http_headers = { "Authorization" = "Bearer <YOUR_API_KEY>" }

Replace <YOUR_API_KEY> with your key.

Check it
