Description
Implements Chrome's native messaging protocol (4-byte length prefix + JSON over stdin/stdout). Creates a Unix domain socket server at a secure path and proxies MCP messages between Chrome extensions and local Claude Code instances. Has its own debug log at ~/.claude/debug/chrome-native-host.txt (ant-only). Launched only when Chrome calls the registered native messaging host binary.
