OuEstCharlie — Wally
Wally is the search/consumption agent for OuEstCharlie. It is stateless and read-only: Woof launches it as a child process (MCP server over stdio), passes a structured search predicate via search_photos, and Wally returns matching photo metadata by traversing the manifest tree. It never reads XMP sidecars or writes anything.

Repository Structure

Installation
From PyPI (recommended)
pip install wally
System prerequisites:
- macOS:
brew install inih brotli gettext(required by pyexiv2 at runtime) - Linux/Windows: no extra steps
From source (development)
Requires the sibling ouestcharlie-py-toolkit repo:
uv venv
uv sync
Running Tests
.venv/bin/pytest tests/ -v
MCP Inspector
Wally runs as a standalone HTTP server (streamable HTTP transport), so it cannot use mcp dev. Start it manually and connect the Inspector to the printed port:
WOOF_BACKEND_CONFIG='{"type":"filesystem","root":"/path/to/photos","name":"my-backend"}' \
.venv/bin/python -m wally
# stdout: WALLY_READY port=<port>
Then start the Inspector and connect to http://127.0.0.1:<port>/mcp (no auth token needed when WOOF_AGENT_TOKEN is unset):
npx @modelcontextprotocol/inspector
Note: The default MCP Inspector timeout is too low for large-library search queries. Increase it in the Inspector settings before calling
search_photos.
