Install Pusher Channels in mcp-client-cli

What you need first

• mcp-client-cli, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_PUSHER_APP_ID,YOUR_PUSHER_KEY,YOUR_PUSHER_SECRET,YOUR_PUSHER_CLUSTER.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "pusher-mcp-server": {
      "command": "npx",
      "args": ["-y", "@crashbytes/[email protected]"],
      "env": { "PUSHER_APP_ID": "YOUR_PUSHER_APP_ID", "PUSHER_KEY": "YOUR_PUSHER_KEY", "PUSHER_SECRET": "YOUR_PUSHER_SECRET", "PUSHER_CLUSTER": "YOUR_PUSHER_CLUSTER" }
    }
  }
}

3. Replace YOUR_PUSHER_APP_ID,YOUR_PUSHER_KEY,YOUR_PUSHER_SECRET,YOUR_PUSHER_CLUSTER with your own values.
4. Save the file and restart mcp-client-cli.

Check it worked

Ask mcp-client-cli: List the tools of pusher-mcp-server.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that mcp-client-cli sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

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

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
