Needle

Connects Claude to Needle's document management and semantic search API. You get tools to create collections, add documents from URLs or files, and run natural language searches across PDFs, DOCX, and other formats. The server handles both document ingestion and retrieval, so you can ask Claude to search through technical documentation or research papers you've stored in Needle collections. Supports remote deployment via their hosted MCP endpoint or local installation with UV. Reach for this when you need persistent RAG capabilities without building your own vector database, especially if you're already managing documents in Needle's ecosystem.
