Devon

DEVONthink MCP server for Claude Code. Zero-config setup — one command and you're done.

33 tools for full DEVONthink integration — search, CRUD, AI, tags, smart groups, email threading, and more. All MIT-licensed, zero external dependencies beyond the MCP SDK.

---

If you have Claude Code, just ask:

> "Hey Claude, clone Devon from github.com/mnott/Devon and set it up for me"

Claude will clone the repo, build it, configure ~/.claude.json, and enable the server. Restart Claude Code and all 33 DEVONthink tools are available.

---

With this server running, Claude Code can:

• Search and browse all open DEVONthink databases
• Read document content (PDFs, Markdown, plain text, HTML, rich text)
• Create, update, and delete records
• Move, replicate, duplicate, and convert records across groups
• Add and remove tags, classify documents, manage metadata
• Ask DEVONthink's built-in AI about documents and create summaries
• Cross-reference emails with archived documents
• List and navigate database groups
• List smart groups and smart rules (not accessible via AppleScript)
• Parse EML headers for email thread correlation
• Read and copy column layout configurations

• macOS (DEVONthink is macOS-only)
• DEVONthink 3 or 4 installed and running
• Node.js >= 18

In Claude Code, ask Claude to set it up:

> "Clone Devon from github.com/mnott/Devon into ~/dev/ai and configure it"

Claude clones, builds, configures ~/.claude.json, and enables the MCP server.

npx @tekmidian/devon setup

Interactive CLI that checks prerequisites, configures ~/.claude.json, and enables the server.

git clone https://github.com/mnott/Devon ~/dev/ai/devon
cd ~/dev/ai/devon
npm install
npm run build
node dist/index.js setup
