Show HN: Browserr – An MCP-first browser for AI agents (one Rust binary)

Browserr is an MCP-first browser for AI agents built on the Servo engine, distributed as a single ~120 MB Rust binary with a 22-command JSON-over-loopback protocol and 42 MCP tools. It emphasizes agent-first design—structured extraction, stable refs, fail-closed interception, built-in adblock, and evidence logging—plus human handoff via a native window with headed:true. It is free and open source, with packages for Windows x64, Linux x64/ARM64, and macOS Apple Silicon, requiring Python 3.10+ for the SDK and MCP server.
