Live web grounding in Claude Desktop

`search_web_jina` gives your Claude Desktop client the ability to run semantic searches across the live web during your chat sessions. Instead of relying on training data from last year, Claude pulls fresh search results to answer time-sensitive questions. Once you locate the right pages, `read_url_content` extracts the raw text directly into your active chat window as clean markdown. You skip the cookie banners and ads, giving the model pure text to analyze or summarize instantly.

Smart document retrieval inside Claude Desktop

`segment_content` splits massive articles or documents into logical, semantic chunks directly inside your Claude Desktop workspace. This stops the model from losing context when you feed it massive files that exceed standard window limits. Right after chunking, `rerank_documents` sorts those text blocks to feed Claude Desktop the most relevant context. You get the most relevant paragraphs pushed to the top of Claude's context, which keeps your local RAG system running fast and accurate.

Run local text classification with this MCP Server

`classify_texts` lets you organize incoming chat transcripts or feedback inside Claude Desktop without training a custom model. You pass a list of categories, and the tool labels your text arrays on the fly. When you need to prepare data for a vector database, `generate_embeddings` converts your text strings into vectors directly within your Claude Desktop interface. Claude Desktop handles the API handshake, letting you build search indexes right from your chat prompt.
