Dewey

meetdewey/mcp

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.

Configuration

DEWEY_API_KEY*secret

Your Dewey project API key

DEWEY_COLLECTION_ID

Default collection ID. When set, tools that accept collection_id fall back to this value.

DEWEY_API_URL

Override the API base URL (default: https://api.meetdewey.com/v1)

Readme

@meetdewey/mcp

MCP server for Dewey — search and research your document collections from Claude, Cursor, and any MCP-compatible agent. See the full API reference for details.

Installation

Add to your claude_desktop_config.json (or equivalent MCP client config):

{
  "mcpServers": {
    "dewey": {
      "command": "/bin/sh",
      "args": ["-lc", "npx -y @meetdewey/mcp"],
      "env": {
        "DEWEY_API_KEY": "dwy_live_...",
        "DEWEY_COLLECTION_ID": "..."
      }
    }
  }
}

Note for Windows users: replace "command": "/bin/sh" and "args": ["-lc", "npx -y @meetdewey/mcp"] with "command": "npx" and "args": ["-y", "@meetdewey/mcp"] — the login-shell wrapper is only needed on macOS/Linux to pick up Homebrew and nvm PATH entries that Claude Desktop doesn't inherit.
