You can use the AWS node.js SDK which should be available in Lambda without installing it.

var AWS = require('aws-sdk');
var lambda = new AWS.Lambda();
lambda.invoke({
    FunctionName: 'arn:aws:lambda:us-west-2:xxxx:function:FN_NAME',
    Payload: {}, 
  },
  function(err, result) {
    ...
});

As far as I can tell you get most, if not all the cli functionality. See the full documentation here: http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html
