Model Context Protocol: Connecting AI Models to the Real World

AI is evolving very fast. MCP is the protocol fueling the world of Agentic AI. Yet, MCP can still be confusing to get especially when you're developer and you think an API should be enough to connect AI Agents to their tools.
In this talk we discuss, evolution of LLM adoption, the new world of Agent AI and how MCP enable us to reach JARVIS-level AI Agents that are able to integrate with our real world tools.

Transcript

1. Model Context Protocol Rygel Louv Connecting AI Models To the Real World
2. Anthropic • Claude AI • Claude Opus 4 and Sonnet 4 • Allegedly Best at coding and writing • Claude Desktop (Canvas, Artifacts, Connectors, Computer Use) • Claude Code (recently) • MCP (November 2024)
3. LLM What is it? (Large Language Model)
4. LLM • Machine learning Models • Understand Human Language • Transformer-based neural network (Deep Learning) • Trained using supervised/self-supervised learning • Predicts and generates human-like text
5. LLM • Token Prediction • During Training sees examples • Understand paterns • During Generation Predicts One Token at a Time You type: "What is the capital of France?" • The model predicts one token at a time: 1."The" 2." capital" 3." of" 4." France" 5." is" 6." Paris" 7."." It keeps generating until it decides to stop (based on probabilities or stop tokens).
6. LLM Generative AI Text Image Audio Video
7. LLM = Brain
8. ChatGPT What is it?
9. ChatGPT •Brain with Sensory Organs •Eyes to see •Ears to hear/listen •Mouth to Speak •Input •Output System
10. ChatGPT
11. Quick Evolution of LLMs Adoption • Reasoning models • Better decision making • Tool Calling • Ready for real life integration Late 2022 Late 2024
12. ChatGPT
13. LLMs alone cannot cause E ff ects in the Real World
14. LLMs + Tools • Book Flights • Order food • Search the web • Execute Code • Manage Calendar
15. LLMs + Tools
16. Agentic AI
17. What is an AI Agent? Autonomous System that independently accomplish tasks on your behalf - OpenAI
18. Agentic AI Late 2022 Late 2024 2025 The Year of Agents
19. Agentic AI We have seen it before In the movies JARVIS
20. For LMMs to cause e ff ects we need: Integrations Source: Kent C Dodds
21. Agentic AI Core components • Prompts • Resources • Tools
22. Context Prompts Resources Tools
23. Context is King 👑
24. How to give Context? • Manually (add docs etc) • RAG (Retrieval Augmented Generation) • Prompt Engineering • Tool Calling (Act, cause e ff ects)
25. Tool Calling Techniques • Function Calling APIs • Prompt Engineering Issues and limitations
26. The Need for a Standardized way to Communicate A Protocol
27. Timeline of Ground Breaking Technology Innovations • 1970s - Personal computers • 1997 - 2000 - Web and dot com • 2004 - Social Medias AI is at this stage ☝
28. Internet Protocols • TCP/IP HTTP === Web • SMTP • FTP
29. Replace Human with AI Agents
30. Tool Calling And Context Issues • Function Calling • We could just use APIs? •How about OpenAPI Specs?
31. Agents: LLM + Tools
32. A New Protocol
33. MCP Open Standard that enables AI Models to connect to External Data sources and tools Rather than requiring custom integrations for each system
34. MCP
35. MCP The USB-C Port for AI Applications
36. MCP Host (Claude Desktop, Cursor, Windsurf, Custom AI App) MCP Client Tools Resources Prompts Capabilities MCP Server Stdio HTTP/SSE (Deprecated) Streamable HTTP JSON-RPC
37. JSON-RPC Server Client Client Server
38. MCP Host (Claude Desktop, Cursor, Windsurf, Custom AI App) MCP Client Tools Resources Prompts Capabilities MCP Server Stdio HTTP/SSE (Deprecated) Streamable HTTP JSON-RPC Prom pt Data Perform Actions I w ant to send Docum ent X To Notion LLM
39. MCP considerations • Technical challenges for real time connections • Security • Authentication • Prompt Injection
40. Demo? Add a missing feature to Claude Desktop
41. Demo? Make Claude Desktop Generate Image Image Generation Tool Generate Image Image Url Image Url Generate Image MCP
42. The Hype is Real
43. Other Agentic AI Protocols A2A by Google AG-UI by CopilotKit
