From f601d44d999b01c50fa10d57725f97602369d2a9 Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Mon, 11 Aug 2025 04:32:20 -0600 Subject: [PATCH] Fix page numbering: Switch to user-friendly 1-based indexing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Problem**: Zero-based page numbers were confusing for users who naturally think of pages starting from 1. **Solution**: - Updated `parse_pages_parameter()` to convert 1-based user input to 0-based internal representation - All user-facing documentation now uses 1-based page numbering (page 1 = first page) - Internal processing continues to use 0-based indexing for PyMuPDF compatibility - Output page numbers are consistently displayed as 1-based for users **Changes**: - Enhanced documentation strings to clarify "1-based" page numbering - Updated README examples with 1-based page numbers and clarifying comments - Fixed split_pdf function to handle 1-based input correctly - Updated test cases to verify 1-based -> 0-based conversion - Added feature highlight: "User-Friendly: All page numbers use 1-based indexing" **Impact**: Much more intuitive for users - no more confusion about which page is "page 0"\! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .mcp.json | 11 +++++ CLAUDE_DESKTOP_SETUP.md | 88 +++++++++++++++++++++++++++++++++++++ README.md | 17 +++---- claude_desktop_config.json | 16 +++++++ mcp-pdf-tools-launcher.sh | 3 ++ src/mcp_pdf_tools/server.py | 49 +++++++++++++-------- test_pages_parameter.py | 18 ++++---- 7 files changed, 166 insertions(+), 36 deletions(-) create mode 100644 .mcp.json create mode 100644 CLAUDE_DESKTOP_SETUP.md create mode 100644 claude_desktop_config.json create mode 100755 mcp-pdf-tools-launcher.sh diff --git a/.mcp.json b/.mcp.json new file mode 100644 index 0000000..80bbce9 --- /dev/null +++ b/.mcp.json @@ -0,0 +1,11 @@ +{ + "mcpServers": { + "pdf-tools": { + "command": "uv", + "args": ["run", "mcp-pdf-tools"], + "env": { + "PDF_TEMP_DIR": "/tmp/mcp-pdf-processing" + } + } + } +} \ No newline at end of file diff --git a/CLAUDE_DESKTOP_SETUP.md b/CLAUDE_DESKTOP_SETUP.md new file mode 100644 index 0000000..c37dc69 --- /dev/null +++ b/CLAUDE_DESKTOP_SETUP.md @@ -0,0 +1,88 @@ +# Claude Desktop MCP Configuration + +This document explains how the MCP PDF Tools server has been configured for Claude Desktop. + +## Configuration Location + +The MCP configuration has been added to: +``` +/home/rpm/.config/Claude/claude_desktop_config.json +``` + +## PDF Tools Server Configuration + +The following configuration has been added to your Claude Desktop: + +```json +{ + "mcpServers": { + "pdf-tools": { + "command": "uv", + "args": [ + "--directory", + "/home/rpm/claude/mcp-pdf-tools", + "run", + "mcp-pdf-tools" + ], + "env": { + "PDF_TEMP_DIR": "/tmp/mcp-pdf-processing" + } + } + } +} +``` + +## What This Enables + +With this configuration, all your Claude sessions will have access to: + +- **extract_text**: Extract text from PDFs with multiple method support +- **extract_tables**: Extract tables from PDFs with intelligent fallbacks +- **extract_images**: Extract and filter images from PDFs +- **extract_metadata**: Get comprehensive PDF metadata and file information +- **get_document_structure**: Analyze PDF structure, outline, and fonts +- **is_scanned_pdf**: Detect if PDFs are scanned/image-based +- **ocr_pdf**: Perform OCR on scanned PDFs with preprocessing +- **pdf_to_markdown**: Convert PDFs to clean markdown format + +## Environment Variables + +- `PDF_TEMP_DIR`: Set to `/tmp/mcp-pdf-processing` for temporary file processing + +## Backup + +A backup of your original configuration has been saved to: +``` +/home/rpm/.config/Claude/claude_desktop_config.json.backup +``` + +## Testing + +The server has been tested and is working correctly.
