Obscura
A Rust-based headless browser engine that exposes Chrome DevTools Protocol capabilities through MCP, letting Claude navigate pages, execute JavaScript, and extract content without spinning up full Chrome instances. You get the core browser automation primitives (navigation, script execution, DOM access) in a 30MB footprint with built-in anti-detection features. Drop it in when you need web scraping or page interaction that's lighter and faster than Puppeteer over headless Chrome, especially if you're running multiple concurrent browser sessions or need to avoid common bot fingerprints. Works with existing Puppeteer and Playwright code, so you can swap the engine without rewriting your automation scripts.
