Install Open Health Sync in Codex

What you need first

• Codex, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_OHS_MCP_URL,YOUR_OHS_MCP_KEY.

Steps

1. Run this in a terminal. It writes the server into ~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.

codex mcp add open-health-sync --env OHS_MCP_URL=YOUR_OHS_MCP_URL --env OHS_MCP_KEY=YOUR_OHS_MCP_KEY -- docker run -i --rm -e OHS_MCP_URL -e OHS_MCP_KEY ghcr.io/soma-intelligence/open-health-sync:0.2.0 mcp

2. Replace YOUR_OHS_MCP_URL,YOUR_OHS_MCP_KEY with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of open-health-sync.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Codex.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
