An MCP (Model Context Protocol) server for interacting with a Paperless-NGX API server. This server provides tools for managing documents, tags, correspondents, and document types in your Paperless-NGX instance.

To install Paperless NGX MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @nloui/paperless-mcp --client claude

1. Install the MCP server:

npm install -g paperless-mcp

2. Add it to your Claude's MCP configuration:

For VSCode extension, edit ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json:

{
  "mcpServers": {
    "paperless": {
      "command": "npx",
      "args": ["paperless-mcp", "http://your-paperless-instance:8000", "your-api-token"]
    }
  }
}

For Claude desktop app, edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "paperless": {
      "command": "npx",
      "args": ["paperless-mcp", "http://your-paperless-instance:8000", "your-api-token"]
    }
  }
}

3. Get your API token:

   1. Log into your Paperless-NGX instance
   2. Click your username in the top right
   3. Select "My Profile"
   4. Click the circular arrow button to generate a new token

4. Replace the placeholders in your MCP config:

   • http://your-paperless-instance:8000 with your Paperless-NGX URL
   • your-api-token with the token you just generated
