rails-ai-context vs pdf-mcp

rails-ai-context: rails-ai-context auto-introspects your Rails app and provides context to AI assistants via MCP, saving tokens and reducing discovery overhead. It generates context files for multiple AI tools and offers 11 MCP tools with smart detail levels.; pdf-mcp: pdf-mcp is a Model Context Protocol (MCP) server that enables AI agents to read, search, and extract content from PDF files. It uses PyMuPDF for PDF parsing, SQLite for persistent caching, and supports hybrid search combining BM25 keyword and semantic embeddings, OCR for scanned documents, and structured extraction of tables and images.
