End-to-end testing (MCP client -> FastMCP -> Django) surfaced a 500:
adding an item with an explicit `unit: null` (as add_to_pantry sends
for items without a unit) hit a NOT NULL violation, because
`item_data.get("unit", "items")` returns None when the key is present.
- views.bulk_pantry_add: `item_data.get("unit") or "items"` — tolerate
null/empty unit.
- mcp_server add_to_pantry: omit quantity/unit from the payload when
unset, so the API applies its own defaults.
- test: bulk-add with unit/quantity = null returns 201 (25 pass).

A standalone MCP server (no Django import) exposing 7 tools over
Streamable HTTP, backed by the Django REST API via the caine token.
- mcp_server/: client.py (httpx wrapper over /api/), server.py (the
tools + FastMCP app + main), __main__.py, tests.py.
- Tools: get_pantry, set_item_state, add_to_pantry, what_can_i_cook,
get_recipes, log_cook (suggests, never mutates), create_meta_recipe
(brainstorm -> commit). Each description says when to call it.
- deploy/food-mcp.service: systemd unit (own process, runs .venv python
-m mcp_server, loads /var/lib/food/.env).
- deploy/food.tomflux.xyz.nginx: current config + an authless
/mcp/<secret>/ location proxying to 127.0.0.1:8765 (the URL secret is
the credential; SSE-friendly buffering/timeout).
- pyproject: [dependency-groups] mcp = [fastmcp, httpx]; deploy with
`uv sync --group mcp`.
Verified: 7 tools register on fastmcp 3.x, run() accepts transport/
host/port/path, 6 FoodClient unit tests pass (httpx MockTransport).
