Distill MCP Server

Let Claude, Cursor, or any MCP client rename files for you — automatically, based on content.

This is the official Model Context Protocol bridge for Distill — a native macOS app that uses AI (Claude, OpenAI, Gemini, Ollama, or Apple Intelligence) to read your files and rename them with descriptive, consistent names. No more IMG_4521.jpg or Scan_003.pdf — get 250401 Invoice Telekom.pdf instead.

You need the Distill app installed and running. This MCP server is a stdio→HTTP bridge — the actual file analysis happens in the app. Get Distill at store.juergenkoller.software/apps/distill.

What you can do

"Claude, look at the 47 PDFs in ~/Downloads, rename them based on content, but show me the suggestions first."

The MCP server exposes 9 tools:

Distill reads PDFs, images (via OCR), Office documents, emails, HTML, RTF, and media files. It extracts date, category, description, sender, and amounts — then builds filenames using your configurable rules.

Configuration

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "distill": {
      "command": "/path/to/DistillMCP",
      "env": {
        "DISTILL_PORT": "22200",
        "DISTILL_TOKEN": "your-token-here"
      }
    }
  }
}

Find DISTILL_TOKEN in Distill → Settings → API & MCP.

Claude Code

claude mcp add distill /path/to/DistillMCP \
  --env DISTILL_PORT=22200 \
  --env DISTILL_TOKEN=your-token-here

Cursor / other MCP clients

Same pattern — DistillMCP is a stdio MCP server, configured via the two env vars above.

How it works

┌────────────────┐  JSON-RPC stdio   ┌────────────────┐  HTTP+Bearer   ┌────────────────┐
│  Claude/Cursor │ ───────────────►  │  DistillMCP    │ ─────────────► │  Distill.app   │
│  (MCP client)  │ ◄───────────────  │   (this repo)  │ ◄───────────── │  (port 22200)  │
└────────────────┘                   └────────────────┘                └────────────────┘

The bridge reads JSON-RPC 2.0 requests from stdin, forwards them to Distill's local HTTP server at 127.0.0.1:22200/mcp, and writes responses back to stdout. All AI calls (Claude/OpenAI/Gemini/Ollama/Apple Intelligence), file reading (OCR, PDF extraction, Office parsing), credit tracking, and naming logic happen inside the Distill app.

This split lets the wire format stay open-source (audit it, sandbox it, run it through any MCP runtime) while the heavy lifting stays in the app.

Environment variables

Errors and trace logs go to stderr so they don't pollute the JSON-RPC stdout channel.
