DEVONthink MCP Server

This MCP server provides access to DEVONthink functionality via the Model Context Protocol (MCP). It enables listing, searching, creating, modifying, and managing records and databases in DEVONthink Pro on macOS. Additionally, it includes tools to resolve bibliography metadata for DEVONthink attachments based on exported bibliography data.

Features

• Exposes a comprehensive set of DEVONthink operations as MCP tools
• List, search, and look up records by various attributes
• Create, delete, move, and rename records and groups
• Retrieve and modify record content, properties, and tags
• Create records from URLs in multiple formats
• List open databases and group contents
• Resolve bibliography metadata for DEVONthink attachments via bibliography exports
• Locate DEVONthink records directly from citation keys or attachment metadata
• All tools are type-safe and validated with Zod schemas

Installation

Claude Code

claude mcp add --scope user devonthink --env BIBLIOGRAPHY_JSON=/path/to/bibliography.json -- npx -y github:TomBener/devonthink-mcp

The --scope user flag installs the MCP server for your user account (available in all projects). You can also use --scope local for the current workspace only.

Codex

codex mcp add devonthink --env BIBLIOGRAPHY_JSON=/path/to/bibliography.json -- npx -y github:TomBener/devonthink-mcp

Configuration

Claude Desktop

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "devonthink": {
      "command": "npx",
      "args": ["-y", "github:TomBener/devonthink-mcp"],
      "env": {
        "BIBLIOGRAPHY_JSON": "/path/to/bibliography.json"
        // "BIBLIOGRAPHY_BIB": "/path/to/bibliography.bib"
      }
    }
  }
}

VS Code

Add to your VS Code MCP settings (~/Library/Application Support/Code/User/mcp.json):

{
  "servers": {
    "devonthink": {
      "command": "npx",
      "args": ["-y", "github:TomBener/devonthink-mcp"],
      "env": {
        "BIBLIOGRAPHY_JSON": "/path/to/bibliography.json"
        // "BIBLIOGRAPHY_BIB": "/path/to/bibliography.bib"
      }
    }
  }
}

Implementation Details

• Uses JXA (JavaScript for Automation) to control DEVONthink via AppleScript APIs
• All tool inputs are validated with Zod schemas for safety and clarity
• Returns structured JSON for all tool outputs
• Implements robust error handling for all operations
• Includes comprehensive tests using Vitest

See CLAUDE.md for full documentation, tool development guidelines, and API reference.

Bibliography Metadata Lookup

Bibliography attachments stored in DEVONthink can be matched to exported bibliography metadata. The MCP server inspects both JSON and BibTeX exports and prefers JSON when both are present.

1. Export your bibliography library (or a subset) to .json or .bib in Zotero.

2. Point the server at the exports via environment variables before launching it (using Claude's MCP configuration or your shell):

   export BIBLIOGRAPHY_JSON="/path/to/bibliography.json"
   export BIBLIOGRAPHY_BIB="/path/to/bibliography.bib"
   

   • Supplying only one file is fine—the server detects whether you provided a .json or .bib path and uses it automatically.
   • If no metadata file is configured, the tool returns an informative error so you can correct the setup.

3. Call the get_bib_metadata tool with a Finder path or any supported DEVONthink identifier. The tool returns the matched bibliography entry (including citation key, fields, and the property that matched), exposes citationKey / bibliographyId at the top level, and provides a brief metadataSummary string for LLM prompts. If no match is found, the response lists the files that were checked.

Example invocation:

  "uuid": "7F8C5A5B-1234-5678-ABCD-9876543210EF"
