First crack at tooling api plugin.

tooling-plugin-test.js

var nforce = require('nforce'),
  tooling = require('nforce-tooling')(nforce);

var sfuser = username
var sfpass = password;

var org = nforce.createConnection({
  clientId: '3MVG9A2kN3Bn17ht1YQvQ6nm.jFel8rlyJZmshbAk1q2jOWva9KnNpzRoTR5n2LxulHbXMm0UucBJiOk_Rx7b',

  redirectUri: 'http://localhost:3000/oauth/_callback',
  mode: 'single',
  plugins: ['tooling']
});

org.authenticate({ username: sfuser, password: sfpass}, function(err, resp){
  if(!err) {
    createContainerTest(resp);
  } else {
    console.log('Error connecting to Salesforce: ' + err.message);
  }
});   

function createContainerTest(oauth) {

    org.tooling.createContainer('testContainer1', oauth, function(err, resp) {
      if (err) console.log(err);
      if (!err) console.log(resp);
    });

}

function queryTest(oauth) {

    var q = 'SELECT+Id,+Name+FROM+ApexClass';
    org.tooling.query(q, oauth, function(err, resp) {
      for(var obj in resp.records) {
        console.log(resp.records[obj].Id + " -- " + resp.records[obj].Name);  
      }   
    });
