🔍 Docsray MCP Server

Docsray is a powerful Model Context Protocol (MCP) server that gives AI assistants like Claude advanced document perception capabilities. Extract text, navigate pages, analyze structure, and understand any document with ease.

✅ Status: Published to PyPI and TestPyPI - Working in Cursor, Claude Desktop, and other MCP clients

✨ Features

🎯 Five Powerful Tools

1. docsray_peek - Quick document overview with format detection and provider capabilities
2. docsray_map - Generate comprehensive document structure maps with caching
3. docsray_xray - AI-powered deep analysis extracting entities, relationships, and insights
4. docsray_extract - Extract content in multiple formats (markdown, text, JSON, tables)
5. docsray_seek - Navigate to specific pages, sections, or search for content

🔌 Multi-Provider Architecture

• PyMuPDF4LLM - Lightning-fast PDF processing (✅ Implemented)

  • Fast markdown extraction
  • Basic table detection
  • Multi-page support
  • Always enabled as fallback

• LlamaParse - Deep document understanding with LLMs (✅ Implemented)

  • AI-powered entity extraction
  • Custom analysis instructions
  • Comprehensive caching in .docsray directories
  • Rich format preservation (markdown, images, tables)

• PyTesseract - OCR for scanned documents (🔄 Planned)

• Mistral OCR - AI-powered OCR and analysis (🔄 Planned)

🚀 Key Benefits

• Universal Input Support - Local files (./path, ../path, /absolute) and URLs (https://)
• Intelligent Provider Selection - Automatically chooses the best tool for each task
• Smart Caching - LlamaParse results cached in .docsray directories for instant access
• Dynamic Discovery - Tools report actual capabilities based on what's enabled
• Production Ready - Comprehensive error handling, logging, and 56 tests
• Self-Documenting - Built-in resources for discovery by MCP clients

📦 Installation

Quick Start with uvx (Recommended)

# Run directly without installation
uvx docsray-mcp start

# Or install globally
uv tool install docsray-mcp
# Then run with:
docsray start
# or
docsray-mcp start

Alternative: Install with pip

# Basic installation (PyMuPDF4LLM only)
pip install docsray-mcp

# With LlamaParse for AI analysis
pip install "docsray-mcp[ai]"

# Development installation
pip install -e ".[dev]"

🚀 Quick Start

1. Set up API Keys (Optional but Recommended)

Create a .env file in your project:

# For AI-powered analysis with LlamaParse
LLAMAPARSE_API_KEY=llx-your-key-here

# Or use environment variables
export LLAMAPARSE_API_KEY=llx-your-key-here

Get your free LlamaParse API key at cloud.llamaindex.ai

2. Configure with Your MCP Client

For Cursor

Add to your Cursor settings:

{
  "mcpServers": {
    "docsray": {
      "command": "uvx",
      "args": ["docsray-mcp"],
      "env": {
        "LLAMAPARSE_API_KEY": "llx-your-key-here"
      }
    }
  }
}

For Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "docsray": {
      "command": "uvx",
      "args": ["docsray-mcp"],
      "env": {
        "LLAMAPARSE_API_KEY": "llx-your-key-here"
      }
    }
  }
}

📚 Usage Examples
