PDF Reader MCP Server for VS Code

An MCP server that enables VS Code to view and analyze PDF documents using the Model Context Protocol (MCP).

This project was created using the Model Context Protocol Python SDK based on FastMCP.

Features

• Open and read PDF documents
• Extract text from PDFs (whole document or specific pages)
• View PDF metadata
• Generate summaries of PDF content
• Extract text from specific pages or page ranges
• Analyze PDF content and answer questions about it

Installation

1. Ensure you have Python 3.13+ installed
2. Clone this repository
3. Create a virtual environment:

uv venv .venv
source .venv/bin/activate

1. Install dependencies:

uv pip install -e .

Docker

You can also run this MCP server using Docker:

Build the Docker Image

docker build -t pdf-reader-mcp .

Run the Container

docker run --name pdf-reader-mcp -it pdf-reader-mcp

Use with VS Code or Claude Desktop

When using Docker, update your MCP configuration to use the Docker container:

VS Code Configuration (Docker)

    "pdf-reader": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "--rm", 
        "-i",
        "pdf-reader-mcp"
      ]
    }
  }
}

Claude Desktop Configuration (Docker)

{
  "mcpServers": {
    "pdf-reader-mcp": {
      "command": "docker",
      "args": [
        "run",
        "--rm", 
        "-i",
        "pdf-reader-mcp"
      ]
    }
  }
}

Usage

This MCP server integrates with VS Code's MCP client to provide PDF reading capabilities. See the Tools and Prompts section below for details on available functionality.

Example Usage

Here's an example of using the PDF Reader to analyze a document:

VS Code Configuration

The server is configured to run in VS Code through the .vscode/mcp.json file. VS Code must have the MCP extension installed to use this server.

To install the VS Code MCP extension:

1. Open VS Code
2. Go to Extensions (Ctrl+Shift+X or Cmd+Shift+X)
3. Search for "Model Context Protocol"
4. Install the extension from Microsoft

Once the extension is installed, VS Code will be able to communicate with this MCP server according to the configuration in your .vscode/mcp.json file. You can use the MCP server through VS Code's Copilot or any other MCP client built into VS Code.

Development

To make changes to this project:

1. Modify the code in the src/pdf_reader_mcp directory
2. Install in development mode: uv pip install -e .
3. Test your changes in VS Code

Requirements

• Python 3.13+
• PyPDF2 3.0.0+
• MCP SDK 1.9.0+ (from github.com/modelcontextprotocol/python-sdk)

  • Takes path as a required string argument
  • Returns a unique PDF ID for referencing in other operations

• close-pdf: Close an open PDF file

  • Takes pdf_id as a required string argument

• list-pdf-metadata: View metadata of an open PDF

  • Takes pdf_id as a required string argument

• get-pdf-page-count: Get the total number of pages in a PDF

  • Takes pdf_id as a required string argument

• get-pdf-page-text: Get the text content of a specific page in a PDF

  • Takes pdf_id as a required string argument
  • Takes page_number as a required integer argument (0-based index)

• pdf-to-text: Extract all text from a PDF document

  • Takes pdf_id as a required string argument
  • Optional include_page_numbers as a boolean (default: true)

  • Required pdf_id argument
  • Required question argument specifying what to analyze
  • Optional page_range argument to focus on specific pages

Quickstart

Install

VS Code

Configure VS Code to use the MCP server by editing .vscode/mcp.json in your project:

{
  "servers": {
    "pdf-reader": {
      "type": "stdio",
      "command": "uv",
      "args": [
        "--directory",
        "${workspaceFolder}",
        "run",
        "python",
        "-c",
        "from pdf_reader_mcp import main; main()"
      ]
    }
  }
}

{
  "servers": {
    "pdf-reader": {
      "type": "stdio",
      "command": "pdf-reader-mcp"
    }
  }
}

Claude Desktop

On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "pdf-reader-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "${workspaceFolder}",
        "run",
        "pdf-reader-mcp"
      ]
    }
  }
}

{
  "mcpServers": {
    "pdf-reader-mcp": {
      "command": "uvx",
      "args": [
        "pdf-reader-mcp"
      ]
    }
  }
}

Development

Building and Publishing

To prepare the package for distribution:

1. Sync dependencies and update lockfile:

uv sync

1. Build package distributions:

uv build

This will create source and wheel distributions in the dist/ directory.

1. Publish to PyPI:

uv publish

Note: You'll need to set PyPI credentials via environment variables or command flags:

• Token: --token or UV_PUBLISH_TOKEN
• Or username/password: --username/UV_PUBLISH_USERNAME and --password/UV_PUBLISH_PASSWORD

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with this command:

npx @modelcontextprotocol/inspector uv --directory "${workspaceFolder}" run pdf-reader-mcp

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
