EzRAG turns your Obsidian vault into a Gemini File Search index so you can run semantic search, chat over your notes, and expose your vault through MCP tools. Everything stays in your Google account; the plugin simply keeps the index up to date.

• Semantic search + AI chat with inline citations
• Smart runner pattern: one desktop keeps the index in sync, other devices can query
• Built-in MCP server so external agents can query or fetch notes
• Automatic deduplication, queue persistence, and rebuild workflows

• Google Gemini API key (get one free)
• Obsidian desktop app for indexing (mobile can query/read-only)

1. Install BRAT from Community Plugins.
