I come from the JavaScript ecosystem

AI can write better then us how to use AI
After talk I will there

Job openings are dramatically descreaing!!
- Significally Fast!

JavaScript is everywhere
- nodejs in IoT
- PS5 interface is in JS !! 🤯

The most tool to create UX
- Every thing is UX
> valda from snapchat

JavaScript solves every UX
- OG tools all resolve this!

Real Probleams
- e.q. Come by MRT, finding the way
- Getting Informations
- Where i go, when i come
- Gettting work done
-

AI also solves UX
- Use **agents**
- Agency -> choice to do task
- As a agency, I choose microphone
- Instead to know how, I can let the agency do this
- Ask then input repeatly, then get the answer

How agents works in practice
- (Demo)
- [Langflow](https://www.langflow.org/)
- Like n8n
- Input -> agent -> output
- Each node
- "列出 10 個質數"
- Tools Just functions
- Everything by JavaScript

MCP content
- "Send me the model"

MCP server

https://www.npmjs.com/package/@modelcontextprotocol/sdk
@modelcontextprotocol
- Register tool

Demo:
- Find way to browse JSDC 2025
- In Chinese mainly ...
- Network bottleneck, searching ...
- It can be outsourcing
- Failed, network issue
- It recogonize the time as UTC

- LangFlow can connect to other MCP servers

- We don't need to open browser, agent can help me

Demo 3:
- AllTrails in ChatGPT
- Book a hotel through booking.com

Bridge of JS + AI -> MCP

# Next step
tej.as
langflow -> MIT License, Open Source

# Q & A
https://app.sli.do/event/wmDrhqire3oymBbcxayPqs
- When integrate more MCPs, that means we would delgate more permissions to those agents to serve it. How we prevent from data hijacked and permission misused?

How to prevent the hjack

- If the future focus of JavaScript is agents, does that imply its importance in frontend will decrease? Could it even mean websites may become less significant?(Less importance of JS?)
- To write agent + MCP applicaitons
- 可以問自己這個問題，你會偏好和chatgpt 對話得到答案，還是偏好自己打開網頁去點擊互動
