blackmount-mcp

Your AI assistant is blind to your browsing life. Claude doesn't know what you researched yesterday, what tabs you have open, or what articles you bookmarked. blackmount-mcp fixes that.

Connect your local browser history, bookmarks, open tabs, and downloads directly to Claude, Cursor, or any MCP client. All data stays on your machine — nothing leaves your disk.

Quick Start

pip install blackmount-mcp

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "blackmount": {
      "command": "blackmount-mcp"
    }
  }
}

Restart Claude Desktop. Done.

"What did I download from arxiv in the last month?"
"Show me everything I've browsed about LLM fine-tuning"
