Extractor by Lightfeed is a TypeScript library that uses LLMs to extract structured data from websites. It handles messy HTML, JavaScript-rendered content, and inconsistent page layouts that break traditional scrapers. Define your schema and let the LLM figure out where the data lives.

Vercel AI SDK 5.0
Native MCP client + streaming agent loops for every model provider

Vercel AI SDK 5.0 is a major release of the open-source TypeScript SDK that lets developers build AI-powered applications across 30+ model providers through a single unified interface. The update ships a built-in MCP (Model Context Protocol) client, persistent agent loop primitives, and first-class structured tool-call streaming — making it dramatically easier to wire up complex, multi-step AI workflows. It abstracts away provider-specific quirks so teams can swap models without rewriting integration logic.
Reviewer scorecard
“Schema-driven extraction with LLM fallback is exactly right. Traditional scrapers break on every site redesign — Extractor adapts because it understands the content semantically. The TypeScript-first approach with strong typing on outputs is chef's kiss for building data pipelines.”
“This is the SDK I've been waiting for. Native MCP client support alone saves me from maintaining a rats' nest of custom glue code, and the unified streaming interface across 30+ providers is a genuine competitive moat. Persistent agent loop primitives are the cherry on top — multi-step reasoning pipelines now feel like first-class citizens rather than weekend hacks.”
“LLM extraction costs add up fast at scale. But for the use cases where you need it — scraping sites with unpredictable layouts, extracting from pages that change frequently — the reliability improvement over CSS selectors easily justifies the token spend.”
“I'll reluctantly admit this one has substance — the MCP integration is genuinely useful, not just a buzzword checkbox. My concern is lock-in: if you're deep in the Vercel ecosystem for deployment, you're now deep in it for your AI layer too, and that's a lot of eggs in one basket. Still, the open-source nature and multi-provider support keep it honest enough to recommend.”
“I have been using this to pull structured data from competitor landing pages and product directories. The schema definition is intuitive and the extraction quality is surprisingly consistent even across wildly different page designs.”
“SDK 5.0 is clearly impressive engineering, but this is squarely for developers with TypeScript chops — there's no low-code on-ramp for creatives who want to build AI-powered tools without writing agent loops from scratch. If you're a designer or content creator hoping to prototype fast, you'll hit a wall quickly and reach for something with a proper UI instead.”
“MCP as a native primitive is the quiet earthquake here — it signals that tool interoperability is becoming the new battleground for AI infrastructure, and Vercel is planting a flag early. Unified streaming agent loops across providers will compound in importance as multi-model orchestration becomes the norm, not the exception. This is the scaffolding the agentic web is being built on.”
