An LLM does not need to understand MCP

news.ycombinator.com Unknown 2025-12-06 22:52:24

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

Create space-saving clones on macOS with Python

news.ycombinator.com Unknown 2025-12-08 15:27:33

Create space-saving clones on macOS with Python The standard Mac filesystem, APFS , has a feature called space-saving clones. This allows you to create multiple copies of a file without using additional disk space – the filesystem only stores a single copy of the data. Although cloned files share data, they’re independent – you can edit one copy without affecting the other (unlike symlinks or hard links). APFS uses a technique called copy-on-write to store the data efficiently on disk – the cl

These protocols will help AI agents navigate our messy lives

technologyreview.com Peter Hall 2025-12-14 23:00:13

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

A vulnerability that researchers call CurXecute is present in almost all versions of the AI-powered code editor Cursor, and can be exploited to execute remote code with developer privileges. The security issue is now identified as CVE-2025-54135 and can be leveraged by feeding the AI agent a malicious prompt to trigger attacker-control commands.
