Overview

Description from the maker (original English)

Agentic search over your Dewey document collections from any MCP-compatible client.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Docs, sheets & office work
  • You need to fill in: DEWEY_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: DEWEY_API_KEY, DEWEY_COLLECTION_ID, DEWEY_API_URL

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is Dewey safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DEWEY_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.4) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

@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.

Environment variables

VariableRequiredDescription
DEWEY_API_KEYYesYour Dewey project API key

dewey_list_contradictionsList detected contradictions — clusters of conflicting claims with explanations and suggested resolutions
dewey_detect_contradictionsTrigger an async contradiction detection run across all claims in a collection
dewey_get_contradiction_runGet the status and stats of the latest contradiction detection run (use to poll after dewey_detect_contradictions)
dewey_resolve_contradictionApply a resolution instruction to a contradiction or dismiss it
Deduplication
ToolDescription
dewey_detect_duplicatesTrigger an async deduplication run — identifies near-duplicate documents by measuring shared content across chunks and marks one per cluster as canonical

dewey_list_duplicate_groupsList near-duplicate groups with canonical + members and coverage percentages
dewey_promote_duplicate_canonicalPromote a different member to canonical; old canonical becomes near_duplicate

Non-canonical documents are excluded from retrieval and contradiction detection. Requires enableDeduplication: true on the collection (set via dewey_update_collection or the Dewey dashboard).

Collection settings
ToolDescription
dewey_get_collection_statsGet document count, storage, section/chunk/claim counts, and processing status breakdown
dewey_update_collectionUpdate collection name, description, research instructions, visibility, and feature flags
dewey_recompute_summariesRe-run AI section summarization across all documents (e.g. after changing the LLM model)
dewey_recompute_captionsRe-run AI captioning for all images and tables across all documents
dewey_delete_collectionPermanently delete a collection and all its data
Research instructions

Collections can have natural-language instructions that are automatically injected into the research system prompt — for example, noting units, preferred sources, or how to handle missing information. They can be set in the Dewey dashboard, via the API, or directly through dewey_update_collection. When dewey_resolve_contradiction is used to apply a resolution, the suggested instruction is also appended here automatically.

Tool usage pattern

A typical read-only research workflow:

  1. dewey_list_collections — discover available collections and understand their purpose
  2. dewey_scan_sections — quickly explore document structure to identify relevant sections
  3. dewey_get_section — load full content of a specific section
  4. dewey_search — retrieve the most relevant chunks for a focused question
  5. dewey_research — run a full agentic research query for questions that need multi-step reasoning

For deeper analysis and curation:

  1. dewey_get_collection_stats — assess how much content has been processed
  2. dewey_list_claims — surface the most important facts across documents
  3. dewey_list_contradictions — identify where documents disagree
  4. dewey_resolve_contradiction — apply or dismiss each contradiction, updating collection instructions automatically
