Claude Context is an MCP (Model Context Protocol) server built by Zilliz—the company behind the Milvus vector database—that solves one of the most annoying problems in AI-assisted development: context window fragmentation. Instead of manually feeding Claude Code snippets of your codebase, Claude Context indexes your entire repo as a vector database and makes it semantically searchable on demand. The tool hooks into Claude Code via MCP, so when you ask Claude to "fix the auth middleware bug," it can automatically retrieve the relevant files, function signatures, and related tests—rather than asking you to paste them in. Zilliz is leaning into their vector DB expertise here: the search is dense embedding-based, not keyword-based, which means it finds conceptually related code even when the variable names don't match. With 6,199 GitHub stars and TypeScript-first implementation, it's already picking up serious developer interest. The main caveat is dependency on Zilliz's infrastructure for the embedding layer, though the repo appears to support local embedding options too. For teams working on large codebases with Claude Code, this is potentially a workflow-changer.

Cua is an open-source infrastructure toolkit for building, benchmarking, and deploying computer-use agents. It provides a unified environment where AI agents can control full desktops across macOS, Linux, and Windows — without stealing the user's cursor or disrupting their workflow. The project ships four components: Cua Driver (background automation for macOS apps), Cua Sandbox (a unified API for VM and container control), CuaBot (multi-agent CLI with native window integration), and Cua-Bench (a benchmark suite compatible with OSWorld and ScreenSpot). Lume, a VM manager optimized for Apple Silicon, rounds out the toolkit. With 15,000+ stars and an MIT license, Cua is quickly becoming the de facto standard for teams building autonomous computer-use pipelines. As agents graduate from chat to "just do the thing," infrastructure like Cua becomes load-bearing.
Reviewer scorecard
“This is the missing piece for Claude Code on large repos. I've been pasting files manually like a caveman—having semantic vector search as an MCP server means the model always has the right context without me playing file manager.”
“Cua solves the hardest part of computer-use agents — getting a stable, reproducible environment that doesn't fight your OS. The background automation mode alone is worth it for devs building macOS agents. 15k stars in a short window is a strong signal.”
“Zilliz isn't doing this out of the goodness of their hearts—they want you on Milvus Cloud. The local embedding path works but requires running your own vector DB, which adds ops burden. Also, 'make the whole codebase context' can actually hurt model performance on tightly scoped tasks.”
“Computer-use agents are still fragile — they miss UI state changes, struggle with dynamic content, and hallucinate element positions. Cua gives you infrastructure, not reliability. Until benchmark scores improve on diverse real-world tasks, this is a research toy with impressive packaging.”
“MCP is becoming the API layer of the agentic era, and tools like this prove it. When coding agents have persistent, semantic memory of your entire codebase, the concept of 'asking the model to understand your code' becomes irrelevant—it already does.”
“Every agentic workflow that touches a UI needs something like Cua. As models improve at visual understanding and cursor control, this infrastructure layer will be what production computer-use runs on. It's early, but it's exactly the right early.”
“As someone who documents and demos developer tools, this removes so much friction from setup tutorials. Claude can now reference the actual project structure without me manually constructing context every time.”
“If you're building an AI that can use Figma, Photoshop, or any creative tool on your behalf, Cua is the missing scaffolding. The benchmarking suite means you can actually measure how well your agent handles design tasks — not just hope.”
