CLI, attach and MCP

npx @singhak/nodeui-cli attach -- node server.js      # console on your app's own port
npx @singhak/nodeui-cli dashboard api=http://127.0.0.1:3000 worker=http://127.0.0.1:3001

attach preloads NodeUI into the process you start (it cannot attach to one that is already running). dashboard is a loopback page that shows health, error rate and p95 for several consoles and opens each through a proxy.

Let an AI agent read it (MCP)

{
  "mcpServers": {
    "nodeui": { "command": "npx", "args": ["@singhak/nodeui-cli", "mcp", "http://127.0.0.1:3000"] }
  }
}

nodeui mcp is a read-only MCP server: an overview digest, grouped errors, requests joined with their queries/outgoing calls/logs, and more. It reads the console API, so data is already masked and no confirmation-gated action is reachable.

See packages/cli for options and limits.
