From Tool Calling to Autonomous AI Agents
Move beyond basic prompting and simple tool calling.
Learn how to engineer AI-powered workflows and production-ready agents that can understand goals, select and execute tools, maintain state, make decisions, interact with external systems and involve humans when necessary.
This hands-on specialization takes you through the complete progression:
LLM → Tools → Workflows → State → Agents → MCP → Controlled Autonomy
You will learn how to connect AI systems with REST APIs, databases, business services and external systems, then evolve those workflows into intelligent agents using LangGraph and MCP.
What You’ll Learn
🔧 1. Tool & Function Calling
Learn how LLMs interact with external capabilities through structured tools.
- Tool schemas
- Function contracts
- Parameter extraction
- Parameter validation
- Structured inputs and outputs
- Tool selection
- Tool execution
- Safe tool invocation
- Tool response handling
Understand the complete flow:
User Request → LLM → Tool Selection → Parameters → Tool Execution → Result → LLM
🔄 2. AI Workflow Engineering
Learn how to build structured workflows that combine:
- LLMs
- Tools
- APIs
- Databases
- Business logic
- State
- Human approval
Using LangChain, you’ll learn how to create reusable AI workflows rather than isolated prompts.
🧩 3. Workflow Engineering Patterns
Understand the major patterns used to build reliable AI workflows:
- Sequential workflows
- Parallel execution

Learn when to use a workflow and when you actually need an agent.
🤖 4. From Workflows to AI Agents
Understand what changes when an AI system moves from a predefined workflow to an agent.
Learn about:
- Goals
- Planning
- Decision-making
- State management
- Tool orchestration

- State
- Nodes
- Edges
- Conditional routing
- Agent loops
- Tool execution
- Persistence
- Human-in-the-loop
- Multi-step execution
- Failure recovery
Build agents that can follow complex execution paths instead of relying on a single LLM response.
🌐 6. MCP — Model Context Protocol

Learn the MCP architecture:
Host → Client → Server → Tools / Resources
Understand:
- MCP Hosts
- MCP Clients

Learn how to prevent uncontrolled AI actions.
Cover:
- Authentication
- Authorization
- Permissions
- Tool contracts
- Parameter validation
- Access control
- Human approval
- Controlled execution
- Isolation
- Secure handling of sensitive operations
The goal is controlled autonomy, not unrestricted autonomy.
🛡️ 9. Reliability & Failure Recovery
Production AI systems must handle failure.
Learn:
- State management
- Retries
- Timeouts
- Fallbacks
- Guard conditions
- Error handling
- Tool failures
- Partial execution
- Recovery strategies
- Human escalation
📊 10. Observability & Execution Monitoring
Understand what happens inside an AI workflow or agent.
Learn to monitor:
- LLM calls
- Tool calls
- Execution paths
- State transitions
- Errors
- Latency
- Token usage
- Agent decisions
- Workflow outcomes
Build systems that are observable rather than black boxes.
🤖 11. AI-Assisted Agent Development
Use modern AI coding agents such as:
OpenAI Codex · Claude Code · GitHub Copilot · Cursor
to accelerate:
- Workflow development
- Agent implementation
- MCP server development
- Debugging
- Testing
- Refactoring
- Optimization
The focus is not simply on generating code, but on using AI coding agents to engineer AI systems faster and more effectively.
🚀 Hands-On Projects
Project 1 — AI Action Workflow
Build v0.3 — Production AI Action Workflow
The system will:
Understand Request → Select Tools → Extract Parameters → Execute Tools → Process Results → Take Next Action → Request Human Approval When Required
Example:
“Check my customer order, verify its status and initiate a refund if it meets the policy.”
The workflow can interact with APIs and business systems while maintaining controlled execution.
Project 2 — AI Agent + MCP Platform
Build v0.4 — Production AI Agent Platform
The agent will:
Understand Goal → Plan → Select Tools → Execute → Observe Results → Decide Next Step → Continue → Complete / Escalate
Using:
LangGraph + MCP + Tools + External Services
The agent can interact with APIs, databases and other external capabilities through MCP.
