Install Pusher Channels in Claude Code

What you need first

• Claude Code, 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. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env PUSHER_APP_ID=YOUR_PUSHER_APP_ID --env PUSHER_KEY=YOUR_PUSHER_KEY --env PUSHER_SECRET=YOUR_PUSHER_SECRET --env PUSHER_CLUSTER=YOUR_PUSHER_CLUSTER --transport stdio pusher-mcp-server -- npx -y @crashbytes/[email protected]

2. Replace YOUR_PUSHER_APP_ID,YOUR_PUSHER_KEY,YOUR_PUSHER_SECRET,YOUR_PUSHER_CLUSTER with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of pusher-mcp-server.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Claude Code 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.
