Clone the repository and enter the directory:

git clone https://github.com/zicez/mcp-pdf2md.git cd mcp-pdf2md

Create a.envfile in the project root directory and set your Mistral AI API key:

MISTRAL_API_KEY=your_mistral_api_key_here

The server supports the following command line arguments:

- --output-dir: Specify the directory to save converted Markdown files and images. Defaults to./downloads.

uv run pdf2md --output-dir /path/to/my/output

Add the following configuration in Claude Desktop:

{ "mcpServers": { "pdf2md": { "command": "uv", "args": [ "--directory", "C:\\path\\to\\mcp-pdf2md", "run", "pdf2md", "--output-dir", "C:\\path\\to\\output" ], "env": { "MISTRAL_API_KEY": "your_mistral_api_key_here" } } } }

{ "mcpServers": { "pdf2md": { "command": "uv", "args": [ "--directory", "/path/to/mcp-pdf2md", "run", "pdf2md", "--output-dir", "/path/to/output" ], "env": { "MISTRAL_API_KEY": "your_mistral_api_key_here" } } } }

Note about API Key Configuration:You can set the API key in two ways:
- In the.envfile within the project directory (recommended for development).
- In the Claude Desktop configuration as shown above (recommended for regular use).

If you set the API key in both places, the one in the Claude Desktop configuration will take precedence.

The server provides the following MCP tools:

- convert_pdf_url(url: str): Converts a PDF from a URL to Markdown. Supports single URLs or multiple URLs separated by spaces, commas, or newlines.
- convert_pdf_file(file_path: str): Converts a local PDF file to Markdown. Supports single or multiple file paths separated by spaces, commas, or newlines.
