Extension Metadata
About this extension
Aether is an ultra token-efficient browser automation bridge connecting AI agents to your active Firefox browser sessions via the Model Context Protocol (MCP).
- Token-Efficient Serialization: Prunes DOM structures into clean, numbered action maps (<1,000 tokens/page) vs 80,000+ raw HTML dumps.
- Active Session Continuity: Operates directly inside your authenticated browser session.
- Universal MCP Support: Works with Claude Desktop, Cursor IDE, Antigravity, and custom agent harnesses.
- 100% Local & Private: In-memory parsing over localhost IPC (127.0.0.1). Zero external telemetry.
