Coders End, from Typers to Thinkers

news.ycombinator.com Elie Teyssedou 2025-09-18 22:54:26

After 10 years in software development, wearing different hats, my approach to building changed in 2025. With AI, I’m finally developing the way I’ve long believed we should. From Typers to Thinkers I’ve genuinely come to believe the real value of my craft lies in architecture: how things are thought out, assembled, structured, and named. I have long considered that the technical part of a project was successful when the code was readable, maintainable, with the right abstractions in the righ

Building a Deep Research Agent Using MCP-Agent

Documenting my journey building a general-purpose deep research agent powered by MCP, and sharing the valuable (and sometimes painful) lessons learned along the way. Background My name is Sarmad Qadri and I'm the creator of the open source project, mcp-agent. My philosophy for agent development in 2025 can be summarized as – MCP is all you need.

The first two pieces I wrote from my head, with reference to things I already knew or to books I’d read.

An LLM does not need to understand MCP

news.ycombinator.com Unknown 2025-11-28 16:52:24

Model Context Protocol (MCP) has become the standard for tool calling when building agents, but contrary to popular belief, your LLM does not need to understand MCP. You might have heard about the term "context engineering"; where you, as the person interacting with an LLM, are responsible for providing the right context to help it answer your questions. To gather this context, you can use tool calling to give the LLM access to a set of tools it can use to fetch information or take actions. MCP

What should these protocols say about security? Researchers and developers still don’t really understand how AI models work, and new vulnerabilities are being discovered all the time. For chatbot-style AI applications, malicious attacks can cause models to do all sorts of bad things, including regurgitating training data and spouting slurs. But for AI agents, which interact with the world on someone’s behalf, the possibilities are far riskier. For example, one AI agent, made to read and send e
