Overview

AI-generated overview

Dewey lets an assistant search, read and research your Dewey document collections, with cited answers, claim and contradiction analysis, and document…

What you can do
  • List collections and search them with hybrid semantic plus keyword search, section scanning and full agentic research with cited answers
  • Read sections and documents as Markdown, list document sections and processing status
  • List extracted claims and detected contradictions, run contradiction detection and apply or dismiss resolutions
  • Run deduplication, list duplicate groups and promote or disband canonical documents
  • Inspect collection stats, update collection settings and research instructions, recompute summaries and captions, retry or delete documents and collections
When to use it
Useful when your research or reference material already lives in Dewey collections and you want an assistant to answer grounded, cited questions from it, or to audit where documents disagree or duplicate each other.
Requirements
A Dewey project API key in DEWEY_API_KEY; optional DEWEY_COLLECTION_ID as a default collection and DEWEY_API_URL to override the API base URL. Runs as a remote endpoint or locally via the npm package @meetdewey/mcp with Node.js (npx). Deduplication features require enableDeduplication on the collection.
Before you install
The API key is a project credential and is passed in the environment. Several tools change or destroy data: deleting documents and collections is permanent, and updates, retries, recomputes, contradiction resolutions and deduplication runs modify collection state and instructions. Document content is sent to Dewey's API for processing and research.

Installation

In SourceWeft

  1. Open Dewey in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.meetdewey%2Fdewey/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

  "mcpServers": {

README

[Dewey]

@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):

json
{  "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_COLLECTION_IDNoDefault collection ID. When set, tools that accept collection_id will fall back to this value.
DEWEY_API_URLNoOverride the API base URL (default: https://api.meetdewey.com/v1)

Available tools

Search & research

ToolDescription
dewey_list_collectionsList all collections in the project, including description and research instructions when set
dewey_searchHybrid semantic + keyword search over chunk content
dewey_scan_sectionsLightweight search over section titles and summaries
dewey_researchAgentic research query with configurable depth — returns a grounded, cited answer
dewey_get_sectionFetch the full Markdown content of a section by ID

Document management

ToolDescription
dewey_list_documentsList documents in a collection with their processing status
dewey_get_document_sectionsList all sections in a document (table of contents with heading levels and IDs)
dewey_get_document_markdownFetch the full converted Markdown content of a document
dewey_retry_documentRetry a failed document — clears error state and re-queues processing
dewey_delete_documentPermanently delete a document and all its derived data

Claims & contradictions

ToolDescription
dewey_list_claimsList extracted factual claims from a collection or specific document, filterable by importance (1–5)
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_get_duplicate_runGet the status and stats of the latest deduplication run (use to poll after dewey_detect_duplicates)
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
dewey_disband_duplicate_groupDisband a group; former members rejoin retrieval as distinct documents

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
