About

A Model Context Protocol (MCP) server that processes PDF documents and intelligently highlights relevant text. It supports basic keyword matching, advanced extractive summarization (using SpaCy and PyTextRank), and clause detection (e.g., finding liability or termination clauses). The server integrates seamlessly into MCP ecosystems via Server-Sent Events (SSE) and returns base64-encoded, annotated PDFs. It can also run as a standalone FastAPI REST service.

Security Report

4.2

Use Caution4.2High Risk

This PDF highlighter MCP server is well-structured with proper error handling and no critical vulnerabilities. Authentication is not required (appropriate for a local service), and file operations use secure temporary file handling. Minor code quality concerns around input validation and broad exception handling prevent a higher score, but permissions appropriately match the server's purpose of PDF processing and NLP analysis. Supply chain analysis found 15 known vulnerabilities in dependencies (0 critical, 11 high severity).
