Codex CLI

Codex CLI reads MCP servers from ~/.codex/config.toml. Connecting to a remote server like Land Insights uses Codex’s newer HTTP client, which you turn on with one setting.

Add this to ~/.codex/config.toml:

experimental_use_rmcp_client = true

[mcp_servers.land_insights]
url = "https://mcp.landinsights.co"

Then sign in:

codex mcp login land_insights

This opens your browser to log in to Land Insights and approve access. There’s no API key, and you don’t need to register a client — Land Insights handles that automatically.

Remote MCP support in Codex is new and still changing. If experimental_use_rmcp_client isn’t recognized in your version, check the Codex MCP docs for the current setting name. Once connected, see what you can do.
