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

See wally_LLD.md

Installation

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.
