Knowledge is a Model Context Protocol (MCP) server that provides a local, private, and persistent knowledge base for AI coding assistants and agentic tools. It allows users to store and semantically search across a wide range of document formats, including PDFs, DOCX, HTML, and images. Key features include intelligent OCR detection for scanned documents, multi-context organization for focused searches, and asynchronous processing for efficient document ingestion. Built on ChromaDB for reliable vector storage, it integrates seamlessly with MCP clients like Claude Desktop and GitHub Copilot CLI, keeping all data processing strictly local to ensure privacy and security.
