try this now :

you can set ctx value :

var LoopBackContext = require('loopback-context');

    MyModel.myMethod = function(cb) {
      var ctx = LoopBackContext.getCurrentContext();
      // Get the current access token
      var accessToken = ctx && ctx.get('accessToken');
      ctx.set('xx', { x: 'xxxx' } );

    }

it's get ctx value :

 module.exports = function(MyModel) {
      MyModel.observe('access', function(ctx, next) {
        const token = ctx.options && ctx.options.accessToken;
        const userId = token && token.userId;
        const modelName = ctx.Model.modelName;
        const scope = ctx.where ? JSON.stringify(ctx.where) : '<all records>';
        console.log('%s: %s accessed %s:%s', new Date(), user, modelName, scope);
        next();
      });
    };

loopback context store userId and accesTokan. in whole web you can access using ctx it's work like session in loopback.
