mcp-unlock-pdf MCP Server: Giving AI Applications Access to Decrypted PDFs

Overview: What is mcp-unlock-pdf MCP Server?

The mcp-unlock-pdf MCP server enables AI applications such as Claude Desktop, Continue, and Cursor to decrypt protected (PDF) documents. By integrating with the Model Context Protocol (MCP), this server provides a seamless and secure way for AI applications to read and analyze encrypted PDFs without the need for manual intervention or local storage of sensitive information.

🔧 Core Features & MCP Capabilities

mcp-unlock-pdf offers robust decryption capabilities, making it indispensable for AI-driven applications that require access to locked PDF documents. This server adheres strictly to MCP's standards ensuring compatibility and interoperability with various MCP clients. The core features include:

• Decryption of Protected Documents: mcp-unlock-pdf can quickly verify the integrity and authenticity of a document before decrypting it.
• Real-Time Accessibility: Decrypted PDFs are made instantly accessible to AI applications, enhancing their ability to provide real-time insights or perform complex analyses.
• Security Compliance: The server ensures secure handling of documents by encrypting them during transmission and only exposing necessary decrypted content when requested.

⚙️ MCP Architecture & Protocol Implementation

The architecture of mcp-unlock-pdf is designed to seamlessly integrate with the MCP protocol, allowing for a smooth data exchange between the AI application (MCP client) and the document source. The protocol implementation involves:

• Configuration Integration: Clients configure their MCP clients to point to the unlock_pdf server as outlined in the example below.
• Execution Flow: When an AI application sends a query to unlock a PDF, it triggers the mcp-unlock-pdf server via the configured command.

🚀 Getting Started with Installation

To get mcp-unlock-pdf up and running, follow these steps:

MCP Configuration

Add the following configuration snippet to your MCP config file (config.json) to enable the unlock_pdf server:

{
  "mcpServers": {
    "unlock_pdf": {
      "command": "uv",
      "args": [
        "--directory",
        "%USERPROFILE%/Documents/GitHub/mcp-unlock-pdf",
        "run",
        "python",
        "main.py"
      ]
    }
  }
}

Start the Server

After saving the configuration, start your MCP client and it should now be able to communicate with mcp-unlock-pdf using the defined command.

💡 Key Use Cases in AI Workflows

Real-world scenarios where mcp-unlock-pdf excels include:

• Legal Compliance: Analyzing sensitive documents for compliance checks across various jurisdictions.
• Financial Analysis: Deciphering encrypted financial reports to identify trends and make informed decisions.
• Market Research: Decrypting customer surveys or feedback forms to extract valuable insights.

By providing decrypted access, mcp-unlock-pdf ensures that these processes are both efficient and secure.

🔌 Integration with MCP Clients

The following table outlines the compatibility matrix for various MCP clients:

MCP Client	Resources	Tools	Prompts
Claude Desktop	✅	✅	✅
Continue	✅	✅	✅
Cursor	❌	✅	❌

Note: The absence of a checkbox (✅) for "Prompts" in the Cursor row indicates that it does not fully support prompt-based interactions with this server.
