PDF to PNG MCP server for AI agents

The PDF to PNG MCP server enables the conversion of PDF documents into PNG images through a simple Model Context Protocol tool call. This server interfaces with your assistant to provide automated document conversion capabilities.

Prerequisites

This server requires the Model Context Protocol (MCP) and several other dependencies:

Python 3.10 or higher
uv package manager
poppler (required for pdf2image)

First, install the MCP SDK:

uv pip install mcp

Installing Poppler

Poppler is required for PDF processing:

Windows: Download and install from poppler-windows
macOS:
```
brew install poppler
```
Linux:
```
sudo apt-get install poppler-utils
```

Installation

Follow these steps to install the PDF to PNG server:

Clone the repository:

git clone https://github.com/truaxki/mcp-Pdf2png.git
cd mcp-Pdf2png

Create and activate a virtual environment:

uv venv

# Windows
.venv\Scripts\activate

# Unix/macOS
source .venv/bin/activate

Install the package:
```
uv pip install -e .
```

Using the Server

Configure MCP Client

Add the server configuration to your claude_desktop_config.json. The file is typically located in:

Windows: %APPDATA%\Claude Desktop\config\claude_desktop_config.json
macOS/Linux: ~/.config/Claude Desktop/config/claude_desktop_config.json

Add this to your configuration file:

{
  "mcpServers": {
    "pdf2png": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/mcp-Pdf2png",
        "run",
        "pdf2png"
      ]
    }
  }
}

Important: Replace /absolute/path/to/mcp-Pdf2png with the actual path where you cloned the repository.

Converting PDFs to PNGs

The server provides a single tool called pdf2png with these parameters:

read_file_path: Absolute path to the input PDF file
write_folder_path: Absolute path to the directory where PNG files should be saved

When you run the conversion, the server:

Converts each PDF page to a separate PNG image
Names the files page_1.png, page_2.png, etc.
Returns a success message with the conversion count

You can invoke this functionality through Claude Desktop or any other MCP-compatible assistant.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "pdf2png" '{"command":"uv","args":["--directory","/absolute/path/to/mcp-Pdf2png","run","pdf2png"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "pdf2png": {
            "command": "uv",
            "args": [
                "--directory",
                "/absolute/path/to/mcp-Pdf2png",
                "run",
                "pdf2png"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "pdf2png": {
            "command": "uv",
            "args": [
                "--directory",
                "/absolute/path/to/mcp-Pdf2png",
                "run",
                "pdf2png"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
