How to install any MCP server

MCP servers work with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client. Here is the general process.

1

Install the server

Most MCP servers install via npx. No global install needed — just add the command to your client config.

npx @zetto/mcp
2

Add to your client config

Each MCP client has a config file where you declare servers. For Claude Desktop, it is claude_desktop_config.json.

{
  "mcpServers": {
    "zetto": {
      "command": "npx",
      "args": ["@zetto/mcp"]
    }
  }
}
3

Start using tools

Restart your client and the server's tools are available immediately. Ask your AI to use them — it discovers capabilities automatically.
