AI MCP Server for n8n: Building Intelligent Workflow Agents

By Upendra -
AI MCP Server for n8n: Building Intelligent Workflow Agents N8n just got a major power-up. With the integration of Model Context Protocol (MCP) servers, you can now build AI-driven workflows that think, reason, and act intelligently. Let me show you what this means and how to use it. What is MCP (Model Context Protocol)? MCP is a new protocol developed by Anthropic that standardizes how AI models like Claude interact with external tools and data sources. Think of it this way: Before MCP: Claude had no standard way to interact with external tools Claude → Custom integration → Tool Claude → Another custom integration → Different tool Claude → Yet another custom integration → Yet another tool With MCP: Clean, standardized protocol Claude → MCP Server ← All tools standardized ↓ Claude uses tools naturally Why This Matters Standardization: Same interface for all tools Simplicity: Developers don't reinvent the wheel Power: Claude can actually use external...

Building Genesis: An AI Agent Meta-Factory

By Upendra -
Building Genesis: An AI Agent Meta-Factory For months, I've been exploring OpenClaw and intelligent agent systems. Today, I'm sharing how I built Genesis —a meta-agent that creates other agents with automatically-generated guardrails. The problem Genesis solves is simple: creating specialized agents is tedious, repetitive, and error-prone. Genesis automates that entire process. The Problem: Agent Creation Is Hard Traditionally, creating a new agent requires: Manual specification : What guardrails does this agent need? Risk assessment : What could go wrong? Permission management : Who approves this? Complexity : Different agents need different constraints Tracking : What agents exist? What can they do? Consistency : Are guardrails applied uniformly? This is slow, inconsistent, and doesn't scale. The Solution: Genesis Genesis is a meta-agent—an agent that creates agents. It works like this: User Request ↓ Genesis Analyzes ("What kind of agent do you n...

Closures in javascript and how do they work ?

By Upendra -
JavaScript Closures for Dummies  Closures Are Not Magic This page explains closures so that a programmer can understand them — using working JavaScript code. It is not for gurus or functional programmers. Closures are  not hard  to understand once the core concept is grokked. However, they are impossible to understand by reading any academic papers or academically oriented information about them! This article is intended for programmers with some programming experience in a mainstream language, and who can read the following JavaScript function: function sayHello ( name ) { var text = 'Hello ' + name ; var sayAlert = function () { alert ( text ); } sayAlert (); } An Example of a Closure Two one sentence summaries: a closure is the local variables for a function — kept alive  after  the function has returned, or a closure is a stack-frame which is  not deallocated  when the function returns (as if a 'stack-fr...
