nginx: match the MCP location with or without a trailing slash

claude.ai strips the trailing slash from the connector URL, so a
location of /mcp/<secret>/ missed and fell to the 301 catch-all. Use a
regex (^/mcp/<secret>/?(.*)$) that matches both and normalises onto the
FastMCP root.

+# MCP Server — Specification
+
+> Written 2026-06-23. Phase 3 of `plan.md`: let claude.ai "cooking mode" read
+> and update the pantry directly, so Tom stops reciting his inventory and pantry
+> upkeep becomes conversational. Builds on the shipped pantry redesign (the
+> `state` field) and auth phase.
+>
+> Decisions locked in `plan.md §3` and `requirements.md §7`: a **separate
+> FastMCP "ai service"** (a pattern Tom already runs elsewhere) that talks to
+> the existing Django REST API, hosted on the same box at
+> **`food.tomflux.xyz/mcp`**, behind nginx, **bearer-token** auth.
+
+---
+
+## 1. Goal
+
+One sentence: **Claude, in claude.ai cooking mode, can see what's actually in
+the pantry and write changes back — without Tom typing his inventory.**
+
+In scope:
+- Read the pantry (what's in / low / out, by location).
+- Update item state conversationally ("used the last of the noodles" → Out).
+- Add items ("bought eggs and pork mince").
+- See what's cookable (the meta-recipe matcher) and the recipe templates
+  (which double as a substitution table).
+- **Commit ideas back** — create/update a meta-recipe Tom brainstormed in the
+  chat, and log a cook (with rating). This is a primary workflow: Tom thinks out
+  loud in the LLM, then wants it saved without re-entering it by hand.
+
+Out of scope (for now): the open-ended "this isn't on the shelf, what else
+works?" reasoning is *Claude's* job given the recipe/slot data — the MCP just
+serves the data; no substitution engine here. Fixed (non-template) recipes stay
+admin-managed; the brainstorm→commit path targets meta-recipes.
+
+**Why the cooking blocks still work:** MCP only gives Claude *tools/data*. It
+doesn't change how claude.ai renders cooking mode. Claude pulls real pantry
+contents through these tools and still produces its normal formatted cooking
+blocks — now grounded instead of guessed.
+
+## 2. Architecture
+
+```
+  claude.ai (cooking mode)
+        │  Streamable HTTP, secret in the URL path
+        ▼
+  nginx  food.tomflux.xyz/mcp   (TLS, public)
+        │  proxy_pass 127.0.0.1:8765
+        ▼
+  FastMCP "ai service"  (food-mcp.service, localhost only)
+        │  HTTP + DRF token  (the `caine` token)
+        ▼
+  Django REST API  127.0.0.1:8042/api/   (localhost — bypasses the
+        │                                  external /api/ nginx block)
+        ▼
+  SQLite
+```
+
+Three trust hops, three credentials:
+- **claude.ai → MCP**: a long random **secret in the connector URL path**
+  (see §4). This endpoint is internet-exposed, so that secret is the only thing
+  protecting it.
+- **MCP → Django API**: the existing `caine` DRF token, over `127.0.0.1` — so
+  it reaches Django directly and isn't subject to nginx's external `/api/`
+  block.
+- **Django → DB**: unchanged.
+
+The MCP service is **inbound-only from claude.ai** and **outbound-only to
+localhost Django**. It holds no database connection of its own.
+
+## 3. Transport & hosting
+
+- **Transport:** Streamable HTTP (the remote-MCP transport claude.ai connectors
+  use). FastMCP served over HTTP, bound to `127.0.0.1:8765`.
+- **Public route:** nginx on `food.tomflux.xyz`, `location /mcp` →
+  `proxy_pass http://127.0.0.1:8765`. TLS via the existing Let's Encrypt setup.
+  Note SSE/streaming needs `proxy_buffering off;` and a long
+  `proxy_read_timeout` on that location.
+- **Process:** its own systemd unit `food-mcp.service` alongside `food.service`,
+  runs as `openclaw`, `Restart=on-failure`.
+
+## 4. Auth
+
+**Resolved (checked against Anthropic's connector docs, June 2026):** claude.ai
+custom connectors authenticate a remote MCP server one of two ways — **OAuth**
+(the server must support Dynamic Client Registration; claude.ai runs the
+handshake) or **authless** (no auth). The "Add custom connector" dialog only
+asks for the server **URL**; OAuth client id/secret are optional "Advanced
+settings". There is **no field to paste a static bearer token or custom
+header**, so the original bearer-header plan isn't directly supported. Two ways
+to honour the "tight secret, single user" intent:
+
+- **Recommended — authless connector + secret in the URL path.** Register the
+  connector URL as `https://food.tomflux.xyz/mcp/<long-random-secret>/`. To
+  claude.ai it's an authless server; in reality nginx proxies *only* that exact
+  secret prefix to the FastMCP service and 404s everything else. The URL **is**
+  the bearer-equivalent — it matches Tom's "a tight enough secret, I'm the only
+  user" call with zero OAuth machinery. Treat the URL as the secret: TLS only,
+  keep it out of git, rotate by changing the path.
+- **Heavier but properly revocable — OAuth with Dynamic Client Registration.**
+  FastMCP can front an OAuth provider. Correct and per-grant revocable, but real
+  work for a single-user app. Reach for it only if the URL-secret feels too
+  loose.
+
+To confirm first-hand: claude.ai → Settings → Connectors → **Add custom
+connector** shows a single URL field (OAuth fields under "Advanced settings").
+
+**MCP → Django** is unchanged: the `caine` DRF token in an `Authorization:
+Token …` header, over `127.0.0.1`.
+
+## 5. Tools
+
+Designed for how Claude reasons in conversation — **by ingredient name, not DB
+id**. Each maps to the existing API (with the small additions in §6).
+
+| Tool | Purpose | Params | Returns | Backing call |
+|---|---|---|---|---|
+| `get_pantry` | "What do I have?" | `location?` (fridge/cupboard/freezer), `include_out?` (default false) | items: `{name, state, location, quantity?, unit, expiry?, is_staple}` grouped by location, plus counts | `GET /api/pantry/` |
+| `set_item_state` | The conversational update — "used the last of the noodles" | `ingredient` (name), `state` (in/low/out), `location?` | the updated item | **new** `POST /api/pantry/set-state/` (§6) |
+| `add_to_pantry` | "I bought eggs and pork mince" | `items: [{name, location?, quantity?, unit?}]` | per-item result (created / restocked) | `POST /api/bulk-pantry-add/` |
+| `what_can_i_cook` | Meal options grounded in stock | `servings?` | meta-recipes with `ready/partial/missing` + per-slot availability + expiry warnings | `GET /api/what-can-i-cook/` |
+| `get_recipes` | The templates + their slot options (the substitution table) | — | meta-recipes with slots, options, base ingredients | `GET /api/meta-recipes/` |
+| `log_cook` | Record a cooked meal + rating — the cook-log commit path | `meta_recipe` or `recipe`, `slot_choices?`, `servings?`, `rating?`, `notes?` | cook-log id + `used_ingredients` (a suggestion set to confirm — **no** auto state change) | `POST /api/log-cook/` (§6) |
+| `create_meta_recipe` | Commit a meta-recipe brainstormed in the chat (create or update) | nested template: `name`, `method`, `slots:[{name, options:[{ingredient, qty, unit}]}]`, `base_ingredients:[]` (+ `id` to update) | the saved recipe + any auto-created ingredients | `POST`/`PUT /api/create-meta-recipe/` (already exists) |
+
+Notes:
+- `set_item_state` resolves the name via the existing alias-aware
+  `helpers.find_ingredient`. If a name is ambiguous or unknown, the tool returns
+  a clear error listing close matches so Claude can ask Tom.
+- `get_recipes` is what makes Claude useful for substitutions: a protein slot
+  already lists "pork mince OR chicken", so Claude can suggest swaps from real
+  data before reaching for general world knowledge.
+- Keep the tool set **small and well-described** — current Opus models reach for
+  tools conservatively, so each tool's description states *when* to call it
+  ("Call `set_item_state` when the user says they used up or ran low on
+  something"), not just what it does.
+- `create_meta_recipe` maps to the existing nested create/update endpoint — **no
+  Django change needed**. Claude assembles the slots/options from the brainstorm;
+  the endpoint auto-creates unknown ingredients. Passing an `id` updates an
+  existing template (it rebuilds slots/bases). This + `log_cook` are the
+  brainstorm→commit workflow Tom asked for.
+
+## 6. Django API changes required (the gaps to close)
+
+These are small, live on the Django side, and are the "make the API
+MCP-ready" work. Each ships with a test.
+
+1. **`log_cook` accepts `rating`, returns suggestions, mutates nothing.** Today
+   the endpoint ignores `rating` though the model has the field (research.md §5).
+   Add `rating`, and route creation through model validation so the "exactly one
+   recipe link" rule is enforced (currently bypassed by `objects.create`).
+   **Remove the old auto-deduct path** — instead return `used_ingredients` (base
+   + slot choices) as a suggestion set. Pantry state is only ever changed by
+   `set_item_state` after Tom confirms (presence-based pantry; never silently
+   mutate from a cook log).
+2. **New `POST /api/pantry/set-state/`** — `{ingredient, location?, state}`,
+   resolves by name/alias, sets state, returns the item. Backs `set_item_state`.
+   (Alternative: have the MCP `GET /api/pantry/` then `PATCH /api/pantry/<id>/`
+   — but a by-name endpoint is cleaner and reusable.)
+3. **Make the API matcher presence-based.** `what_can_i_cook` in `views.py`
+   still compares quantities; the web matcher was already moved to presence
+   (have-it beats have-enough). Apply the same change so the MCP and web agree.
+4. **`bulk-pantry-add` restocks instead of duplicating.** It currently matches
+   existing rows by `quantity__gt=0`, so adding an item that's marked Out
+   creates a duplicate. Match by ingredient+location and set `state="in"`
+   (mirror what the web `pantry_add` now does).
+5. **Pantry serializer exposes `state`** — already true (`fields = "__all__"`),
+   just confirm it in a test so it can't regress.
+
+*Note:* `create_meta_recipe` needs **no** Django change — `POST/PUT
+/api/create-meta-recipe/` already does nested create/update with ingredient
+auto-creation. The brainstorm→commit path is otherwise pure MCP plumbing over
+endpoints that exist; the only write-path gap is `log_cook`'s rating (item 1).
+
+## 7. Project layout & dependencies
+
+A small package in this repo, its own process — not bolted into Django:
+
+```
+mcp_server/
+  __init__.py
+  __main__.py        # entrypoint: from .server import main; main()
+  server.py          # FastMCP app + the @mcp.tool definitions (§5) + main()
+  client.py          # thin httpx client around the Django API (caine token)
+  tests.py           # FoodClient tests via httpx.MockTransport (no network)
+```
+
+`main()` runs streamable-HTTP at path `/` on `127.0.0.1:8765`
+(`mcp.run(transport="http", host, port, path="/")`); nginx maps
+`/mcp/<secret>/` → that root. Client tests run with
+`python -m unittest mcp_server.tests` (needs the `mcp` dep group).
+
+- Deps via a uv group so they only install where needed:
+  `[dependency-groups] mcp = ["fastmcp", "httpx"]`. Deploy with
+  `uv sync --group mcp` on the box that runs the service.
+- The service holds no Django import — it's a pure HTTP client of `/api/`.
+  Keeps the two deployables decoupled (Tom's "ai service" pattern).
+
+## 8. Config (env, in `/var/lib/food/.env`)
+
+| Var | Purpose |
+|---|---|
+| `FOOD_MCP_URL_SECRET` | the secret path segment nginx requires on `/mcp/<secret>/` (see §4) |
+| `FOOD_API_BASE` | `http://127.0.0.1:8042/api` |
+| `FOOD_API_TOKEN` | the `caine` DRF token |
+
+All out of git; the systemd unit loads the same `.env` the Django service uses.
+
+## 9. Deployment (sketch)
+
+1. `uv sync --group mcp` on the box.
+2. Add the three env vars to `/var/lib/food/.env`; generate the bearer token.
+3. Install `deploy/food-mcp.service`, `daemon-reload`, start, enable.
+4. Add the `location /mcp` block to the `food.tomflux.xyz` nginx config
+   (`proxy_buffering off`, long read timeout), `nginx -t`, reload.
+5. In claude.ai, add a custom connector pointing at the **secret URL**
+   `https://food.tomflux.xyz/mcp/<secret>/` (authless connector — see §4).
+6. Smoke test: in cooking mode, "what's in my pantry?" → Claude calls
+   `get_pantry` and lists real items.
+
+## 10. Conventions & error handling
+
+- Tools return **structured, compact** results (names + states), not raw API
+  JSON dumps — keep token cost down and make Claude's job easy.
+- On a Django API error, the tool returns a short plain-language error
+  (`is_error`) so Claude can relay or ask, never a stack trace.
+- All writes are idempotent-ish: setting state to its current value is a no-op;
+  adding an existing item restocks rather than duplicates.
+- Read tools default to excluding `out` items unless asked — "what do I have"
+  shouldn't list everything you're missing.
+
+## 11. Testing
+
+- **Django side:** unit tests for the new `set-state` endpoint, `log_cook`
+  rating, presence-based API matcher, and bulk-add restock (extend
+  `kitchen/tests.py`).
+- **MCP side:** test `client.py` against a stub API; test each tool maps the
+  right call and shapes results. The MCP server itself can be smoke-tested by
+  pointing a local MCP client (or `curl` with the bearer) at it.
+
+!! i should also be able to run the stack on this box and have you auth with it for testing
+
+## 12. Open decisions to confirm before building
+
+1. **claude.ai connector auth** — RESOLVED (§4): no static-bearer field exists,
+   so use an **authless connector + secret in the URL path** (recommended), or
+   OAuth/DCR if that feels too loose.
+2. **Cook-log nudge — RESOLVED:** `log_cook` does **not** auto-change pantry
+   state. It returns `used_ingredients` so Claude can *suggest* marking them
+   Low/Out; Tom confirms, and the change goes through `set_item_state`. Never
+   silently mutate the pantry from a cook log.
+3. **Bearer in nginx vs app** — check the token in nginx, the FastMCP app, or
+   both? Recommended: app (so it's in one place with the tools); nginx optional.
+
+## Build order
+
+1. Close the Django API gaps (§6) on a branch — small, test-covered, mergeable
+   on their own.
+2. Wire the URL-secret gate in nginx (§4) — `location /mcp/<secret>/` proxies,
+   everything else 404s.
+3. Build the FastMCP service (§5, §7) + systemd unit.
+4. nginx `/mcp` + TLS, register the connector, smoke test.
+
+## Definition of done
+
+In claude.ai cooking mode, Tom can say "what can I make tonight?" and Claude
+lists options grounded in the actual pantry; and "I used the last of the
+noodles" updates the pantry — with no manual inventory typing, and the usual
+cooking blocks intact.
