What is Agentic AI?

"Agents" or "Agentic" AI systems are LLM-powered assistants that can take multiple autonomous actions when given prompts or tasks. Unlike traditional conversational AI that simply responds to queries, agentic AI can:

  • Execute specific tasks independently with minimal supervision
  • Reflect and reason about problems through multi-step thinking processes
  • Make decisions based on context, predictions, and classifications
  • Interact with tools and systems to accomplish complex workflows
  • Adapt their approach based on feedback and results

Key Characteristics of Agentic AI

Autonomy

Agentic AI can break down complex requests into subtasks and execute them without requiring step-by-step human guidance. For example, when asked to "fix the bug in the checkout flow," an agentic system might:

  1. Search the codebase for checkout-related files
  2. Identify potential issues by analyzing error patterns
  3. Propose and implement fixes
  4. Run tests to verify the solution
  5. Document the changes made

Tool Use and Integration

Modern agentic AI systems can interact with external tools, APIs, and systems. This is where Model Context Protocol (MCP) becomes crucial. MCP allows AI agents to:

  • Access file systems and databases
  • Execute code and terminal commands
  • Interact with version control systems like Git
  • Connect to web services and APIs
  • Read and modify application state

See our MCP documentation for detailed information on how this protocol enables sophisticated agentic behaviors.

Iterative Problem-Solving

Rather than providing a single response, agentic AI can iterate on solutions. It may:

  • Try an approach, evaluate the results, and adjust
  • Request additional context when needed
  • Backtrack and try alternative strategies
  • Learn from errors within a session

Multi-Step Reasoning

Agentic systems often employ chain-of-thought reasoning, breaking problems into logical steps and maintaining context across a sequence of operations. This is particularly evident in modern coding assistants during vibe coding workflows.

Agentic AI in Practice: Vibe Coding

The term "vibe coding" describes one of the most prominent applications of agentic AI today—where developers collaborate with AI agents directly in their development environment. Modern agentic coding tools include:

  • Claude Code - VS Code extension with autonomous coding capabilities
  • Cursor - Standalone editor with powerful agentic features
  • Cline - Open-source VS Code extension pioneering "bring your own model" approach
  • GitHub Copilot - Integrated agentic coding with GitHub workflows
  • Windsurf - Standalone editor with agentic inline features

These tools demonstrate agentic behavior by:

  • Reading multiple files to understand project context
  • Making coordinated changes across multiple files
  • Running commands in the terminal to test changes
  • Debugging errors and iterating on solutions
  • Suggesting architectural improvements based on codebase analysis

Learn more about these tools in our Vibe Coding guide.

How Agentic AI Works: The Agent Loop

Agentic AI typically operates using a perception-decision-action loop:

flowchart TD
    A[User Request] --> B[Perceive Context]
    B --> C[Plan Actions]
    C --> D[Execute Action]
    D --> E[Observe Results]
    E --> F{Goal Achieved?}
    F -->|No| B
    F -->|Yes| G[Report Completion]

    style A fill:#e1f5ff
    style G fill:#c8e6c9
  1. Perceive: Gather context from the environment (code, files, system state)
  2. Plan: Determine what actions are needed to accomplish the goal
  3. Execute: Perform the action using available tools
  4. Observe: Evaluate the results and any errors
  5. Iterate: Continue until the goal is met or help is needed

Enabling Technologies

Model Context Protocol (MCP)

MCP is foundational for modern agentic AI systems. It provides:

  • Standardized context access across different applications
  • Tool invocation capabilities for executing actions
  • Real-time application state awareness
  • Cross-application coordination potential

Without MCP or similar protocols, AI agents would be limited to conversational assistance. MCP enables them to "see" your work environment and "act" within it. Read our comprehensive MCP guide to understand how this works.

Function Calling / Tool Use

Most modern LLMs support structured function calling, allowing them to:

  • Invoke APIs with specific parameters
  • Execute predefined workflows
  • Query databases or search engines
  • Interact with external services

Extended Context Windows

Larger context windows (200K+ tokens) enable agents to:

  • Maintain awareness of entire projects
  • Reference extensive documentation
  • Track long conversation histories
  • Analyze multiple files simultaneously

Use Cases for Agentic AI

  • Automated code refactoring across multiple files
  • Bug diagnosis and fixing with minimal guidance

The Future of Agentic AI

As agentic AI systems become more sophisticated, we're seeing:

  • Multi-agent systems where specialized agents collaborate
  • Longer-running agents that work on tasks over hours or days
  • Cross-application coordination via protocols like MCP
  • Improved safety mechanisms for autonomous operations
  • Better user control over agent autonomy levels

The combination of vibe coding tools, MCP integration, and increasingly capable LLMs is creating a new paradigm where AI agents become true collaborators in complex workflows.

Best Practices for Working with Agentic AI

  • Start with clear goals: Give agents well-defined objectives
  • Monitor progress: Check in on agent actions, especially when learning
  • Provide feedback: Correct course when the agent goes astray
  • Understand limitations: Know when to take manual control
  • Security awareness: Be cautious with agents that can execute code or access sensitive systems
  • Iterate on prompts: Refine your instructions based on agent behavior

Security Considerations

Agentic AI systems that can execute code, access files, or interact with systems require careful security consideration. Always:

  • Review code before execution in sensitive environments
  • Use appropriate sandboxing and permissions
  • Follow your institution's security policies
  • Be aware of what tools and systems your AI agent can access
