# 📄 MCP PDF Server A PDF file reading server based on [FastMCP](https://github.com/minimaxir/fastmcp). Supports PDF text extraction, OCR recognition, and image extraction via the MCP protocol, with a built-in web debugger for easy testing. --- ## 🚀 Features - **read_pdf_text** Extracts normal text from a PDF (page by page). - **read_by_ocr** Uses OCR to recognize text from scanned or image-based PDFs. - **read_pdf_images** Extracts all images from a specified PDF page (Base64 encoded output). --- ## 📂 Project Structure ``` mcp-pdf-server/ ├── pdf_resources/ # Directory for uploaded and processed PDF files ├── txt_server.py # Main server entry point └── README.md # Project documentation ``` --- ## ⚙️ Installation Recommended Python version: 3.9+ ```bash pip install pymupdf mcp ``` > Note: To use OCR features, you may need a MuPDF build with OCR support or external OCR libraries. --- ## 🔦 Start the Server Run the following command: ```bash python txt_server.py ``` You should see logs like: ``` Serving on http://127.0.0.1:6231 ``` --- ## 🌐 Web Debugging Interface Open your browser and visit: ``` http://127.0.0.1:6231 ``` - Select a tool from the left panel - Fill in parameters on the right panel - Click "Run" to test the tool No coding required — easily debug and test via the web UI. --- ## 🛠️ API Tool List | Tool | Description | Input Parameters | Returns | |:-----|:------------|:-----------------|:--------| | `read_pdf_text` | Extracts normal text from PDF pages | `file_path`, `start_page`, `end_page` | List of page texts | | `read_by_ocr` | Recognizes text via OCR | `file_path`, `start_page`, `end_page`, `language`, `dpi` | OCR extracted text | | `read_pdf_images` | Extracts images from a PDF page | `file_path`, `page_number` | List of images (Base64 encoded) | --- ## 📝 Example Usage Extract text from pages 1 to 5: ```bash mcp run read_pdf_text --args '{"file_path": "pdf_resources/example.pdf", "start_page": 1, "end_page": 5}' ``` Perform OCR recognition on page 1: ```bash mcp run read_by_ocr --args '{"file_path": "pdf_resources/example.pdf", "start_page": 1, "end_page": 1, "language": "eng"}' ``` Extract all images from page 3: ```bash mcp run read_pdf_images --args '{"file_path": "pdf_resources/example.pdf", "page_number": 3}' ``` --- ## 📢 Notes - Files must be placed inside the `pdf_resources/` directory, or an absolute path must be provided. - OCR functionality requires appropriate OCR support in the environment. - When processing large files, adjust memory and timeout settings as needed. --- ## 📜 License This project is licensed under the MIT License.
