Wiring CAI into OpenClaw, Hermes, Codex, and Cursor: the exact MCP config for each host

The general install is one command, npm i -g @cailab/mcp, and the contract lives at cai.com/skill.md. This post is the host-specific deep-dive: the exact config block for OpenClaw, Hermes, Codex, and Cursor, with the path to the config file, the env var handling, and the restart command.

Before you start

You need:

A CAI account (cai.com/app). The signup is four steps, about 2 minutes.
