Woof — See your Photo Gallery in your AI assistant

Status: Early Preview

MCP Server uv

Woof is a media management system that keeps your photos exactly where they are — on your own drives — while giving you a beautiful, searchable gallery powered by your AI assistant (Claude Desktop, Goose...).

No cloud subscription. No proprietary lock-in. Your library, your way.

Woof is the MCP App frontend to "Où est Charlie ?" ("Where is Wally?" in French), a full framework to manage you photos (later movies and other media).

What makes it different

Most photo managers lock your library into a cloud service (Google Photos, iCloud) or require a database server that becomes a single point of failure. Woof takes a different approach:

• Conversation as your gallery. Woof connects to your AI assistant (Claude Desktop, ChatGPT, Goose…) and turns it into a full photo browser. Ask in plain language, get results inline. No separate app to learn.
• Privacy by design. Only metadata travels to your AI assistant — your actual photos are served locally by Woof. Your pictures are never uploaded to any AI service unless you explicitly ask.
• No database lock-in. Metadata lives as XMP sidecar files right next to your photos, plus lightweight JSON manifests. Move a drive, copy a folder — your entire organization travels with your photos.
• Open formats, forever. XMP is an ISO standard. JSON is universal. AVIF is royalty-free. Every tool you already use — Lightroom, darktable, ExifTool — can read your metadata today and long after OuEstCharlie is gone.
• Your photos are never touched. Woof reads your library as-is. It never modifies, moves, or deletes your original files. It also honors existing XMP metadata from Lightroom, darktable, or any other tool — rather than overwriting it.
• Works with your existing folder structure. Just point Woof at your photos folder. No migration, no reorganization required.

Installation

Woof runs as a local MCP server. It connects to your AI desktop client (Claude Desktop, Goose...) and exposes your photo library as a set of tools.

Option A — Bundle install (recommended but Claude Desktop only)

Connect to Claude Desktop

Download the latest ouestcharlie-woof.mcpb from the Releases page and double-click it. Claude Desktop will prompt you to install Woof in one click — no configuration file to edit.

Step by Step install of OuEstCharlie Woof in Claude Desktop

Option B — Manual uvx configuration

Prerequisites

Python packages of OuEstCharlie Woof are managed by uv and the command uvx. uv might be already available on your system.

System prerequisites (all install options):

• macOS: brew install inih brotli gettext (required by pyexiv2 at runtime)
• Linux/Windows: no extra steps

Connect to Claude Desktop

Reference: Getting Started with Local MCP Servers on Claude Desktop

Open (or create) ~/Library/Application Support/Claude/claude_desktop_config.json and add or update mcpServers:

{
  "mcpServers": {
    "woof": {
      "command": "uvx",
      "args": ["--python", "3.13", "--from", "ouestcharlie-woof", "woof"]
    }
  }
}

Restart Claude Desktop. Woof will appear as an MCP integration, and the gallery will render as an interactive panel inside your conversation.

Connect to ChatGPT Desktop

NOTE: As of May 2026, ChatGPT is no longer supporting local MCP servers. Following is not longer available!

Connect to Goose

Reference: Goose MCP extensions documentation

Goose supports MCP servers via its extension system.

Either add through the user interface as a Custom Extension:

Setup Woof extension in Goose

Or add the following to your Goose configuration (~/.config/goose/config.yaml):

extensions:
  woof:
    type: stdio
    cmd: uvx
    args: ["--python", "3.13", "--from", "ouestcharlie-woof", "woof"]
    enabled: true

Other supported AI Assistants

Other clients support MCP Apps, for example VSCode Github Copilot or Codex.

First Steps

1. Register your photos folder

Once Woof is connected to your AI client, ask it to register your photo folder:

"Add a local library to Woof pointing to /Users/yourname/Pictures"

Woof supports any folder on a local drive — including folders synced from iCloud Drive, OneDrive, or Google Drive, as long as the files are locally available.

2. Index your library

Trigger the indexer to scan your photos and build the metadata index:

"Index my local library"

Woof will launch the indexing agent, which will:

• Read EXIF/XMP metadata from each photo
• Write XMP sidecar files alongside your originals (never modifying the originals)
• Generate thumbnails and previews
• Build a fast index for querying

Indexing speed is roughly 10 to 100 seconds per 1,000 photos depending on format and hardware.

3. Start browsing

Once indexing is complete, just ask:

"Show me photos in Woof from last July"

"In Woof, show me pictures taken near Paris"

"Search Woof for photos with 'Tour Eiffel' in the description"

"How many photos do I have in Woof?"

The gallery panel will appear inline in your conversation with matching results.

Storage

V1 supports local filesystem and cloud_mount libraries on macOS, Linux, and Windows:

• filsystem for a standard local hard drive or SSD, including local network drive (e.g. NAS)
• clound_mount for a folder synced from iCloud Drive, OneDrive, Google Drive, or Infomaniak kDrive — as long as files are downloaded and locally accessible

Native cloud storage (S3, Azure, GCS, OneDrive API) is planned for V2.

Status

Woof is an early preview targeting a focused V1 scope:

Feature	Status
Local filesystem indexing (macOS, Linux, Windows)	Working
Mounted cloud drives (iCloud Drive, OneDrive, kDrive)	Working — files must be locally synced
JPEG, PNG, TIFF, HEIC, RAW support	Working (HEIC and RAW dependant on the build options)
Date, dimensions, GPS bounding box, camera make and model, camera settings, tags search	Working
Full-text search on photo description	Working
Sort ascending or descending on any field	Working
Gallery view (Claude Desktop or Goose) as grid or preview	Working
Video support	Planned for V2
Albums and smart filters	Planned for V2
Share pictures with host (Claude Desktop, ChatGPT, Goose...)	Planned for V2
Enrichment agents (faces, scene recognition)	Planned for V2
Change detection / automatic re-indexing	Partial (added and removed pictures)
Mobile companion app	Planned for V3
Native cloud libraries (S3, OneDrive, GCS…)	Planned for V3

What this means for you: V1 works well for browsing and searching a local photo library. If you hit a bug or unexpected behavior, please open an issue.

Privacy Policy

Woof is designed with privacy as a core principle.

• Data collected: Only photo metadata (EXIF, GPS coordinates, camera make/model, dates, file paths) is read and indexed. No account or personal information is collected.
• Data storage: All metadata is stored locally on your own device as XMP sidecar files and JSON manifests alongside your photos. No data is stored on any remote server.
• AI assistant: Only metadata and thumbnail images are sent to your AI assistant (Claude, ChatGPT, Goose…) when you perform a search. Your original photo files are never uploaded to any AI service unless you explicitly share them.
• Third parties: No metadata or usage data is shared with any third party.
• Retention: All data remains under your full control. Deleting the XMP sidecars and .ouestcharlie/ folders from your photo library completely removes all Woof metadata.

For privacy questions, please open an issue.
