Transcript

1. All rights reserved by Postman Inc Aarti Suresh Solutions Engineer - APAC Go with the Flow Build MCP Servers the easy way with Postman.
2. 👋 Aarti, Solutions Engineer at Postman. 💻 More than a decade in QA space prior to solutions engineering. 💡 Anyone can master APIs with curiosity, creativity, and maybe a few cups of coffee! ☕ Who am I?
3. Why MCP?
4. 24% of you plan to explore MCP!
5. AI Agents execute tasks through APIs
6. AI doesnʼt "know" things — it calls APIs.
7. APIs are like the Spinal Cord of AI. • Limbs For physical and digital objects (e.g. websites, communications, robotics) • Senses For detecting and observing information (e.g. log files, service health, IoT sensors) • Memory Storing and retrieving information (e.g. databases or s3 buckets) Enabling AI to use:
8. The MxN integration problem emerges. • Each AI model needs a unique connection to every service. • This slows productivity & increases costs. • Scaling AI is impossible without a simpler, unified solution. https://blog.dailydoseofds.com/p/the-mn-integration-problem-solved
9. Solution: Model Context Protocol • Introduces a standard protocol for AI Clients to access tools and data. • Simplifies integration complexity to MN. • Supports scale • Backed by Anthropic, Google, Microsoft & OpenAI. https://blog.dailydoseofds.com/p/the-mn-integration-problem-solved
10. MCP Architecture: Local or Remote • Local ◦ Distributed via Git/NPM ◦ Code runs locally ◦ Development and Private Data use cases • Remote ◦ Hosted by the vendor ◦ Code runs on cloud ◦ Web agents, ease of use

18. Sample MCP prompts: • Look in my fridge and plan my meal options. • Which of the meal options, based on the contents in my fridge are suitable for children? • I am in a hurry and need to cook something fast. Check my fridge and make suggestions? • I am in the mood for a ‘wine and dineʼ kind of recipe. Look into my fridge and create something!
