What it does

Lightning fast, turnkey indexing, search, and full codebase understanding for AI coding agents. { "ultrasync" : { "type" : "stdio" , "command" : "ultrasync-mcp" } } 3. Index your project Purpose-built indexing returns precisely what your agent needs. No recursive searches, no wasted tokens. Sub-second queries so you don't need to take a coffee break between tool calls. Native Model Context Protocol integration. Your agent gets actionable data, not raw text. $ grep -r "checkout" ./src ./src/checkout/handler.ts:export async function checkout(cart: Cart) { ./src/checkout/handler.ts: // checkout flow starts here ./src/checkout/validation.ts:export function validateCheckout(items) {…from ultrasync.dev

    Codebased combines Tree Sitter for code awareness (find functions, data structures, constants, etc. not just lines of code), full-text search using SQLite, and semantic search using OpenAI embeddings + FAISS. Despite being implemented in Python, supporting semantic search, making multiple API calls for embedding and re-ranking, it is faster than ripgrep for runng searches against the Linux kernel (takes ~1 second vs. ~2 seconds, obviously depends on system, temperature, time of day, tidal forces, etc.) Up next: - A Perplexity-like agent for interpreting results, making multiple follow-up…

  • UltraContext – A simple context API for AI agents with auto-versioningJan 2026 · ultracontext.ai · ▲21

    Hey HN! I'm Fabio and I built UltraContext, a simple context API for AI agents with automatic versioning. After two years building AI agents in production, I experienced firsthand how frustrating it is to manage context at scale. Storing messages, iterating system prompts, debugging behavior and multi-agent patterns—all while keeping track of everything without breaking anything. It was driving me insane. So I built UltraContext. The mental model is git for context: - Updates and deletes automatically create versions (history is never lost) - Replay state at any point The API is 5 methods:…

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
