Dewey

Brings Dewey's document intelligence platform into any MCP client with a complete toolkit for search, research, and content curation. You get hybrid semantic search, agentic research queries with citations, section scanning, and full document management. The more interesting features include claim extraction with importance scoring, automatic contradiction detection across your corpus, and near-duplicate grouping that can exclude redundant documents from retrieval. Collections support custom research instructions that get injected into the system prompt, and contradiction resolutions can update those instructions automatically. Useful when you're working with large document collections that need more than basic RAG, especially if you're chasing down conflicting information or trying to surface high-signal facts from hundreds of pages.
