# Mealie MCP Server

MCP server for Fredrik's Mealie instance. It exposes recipe search, suggestions,
recipe details, ingredient scaling, imports, cover images, ingredient parsing, and a
finished-import verification pass.

It grew out of a working Hermes agent skill. The valuable part of that skill was not
the Mealie endpoints — it was roughly 25 operational rules discovered by running
imports against the live instance and watching them fail. Those rules are the reason
this server exists as code instead of prompt text.

## What lives where

The split is deliberate:

| The server owns (deterministic) | The model owns (judgement) |
|---|---|
| Auth, and the non-default User-Agent Cloudflare requires | Translating content to Swedish |
| The `extension` field on cover uploads | Picking recipes against the taste profile |
| PATCH instead of the bulk-action endpoints | Choosing a variant from an article page |
| Parsing, then restoring the Swedish display text | Sensible categories and tags |
| Decimal-comma normalization before the parser | Judging image quality |

The token never leaves the server, so agents never handle a bearer credential.

## Configuration

```bash
export MEALIE_API_TOKEN='...'                              # required
export MEALIE_BASE_URL='https://recept.famfallman.com'     # optional
export MEALIE_USER_AGENT='Mealie-MCP/0.1'                  # optional, must be non-default

export HA_BASE_URL='http://homeassistant.local:8123'       # optional, shopping list only
export HA_TOKEN='...'
export HA_SHOPPING_LIST_ENTITY='todo.ourgroceries_shoppinglista'

uv run mealie-mcp
```

Create the Mealie token at `/user/profile/api-tokens`.

Home Assistant is optional and isolated: without `HA_BASE_URL` and `HA_TOKEN`
everything except `shopping_list_add` works normally.

## Tools

**Read**
- `check_auth()` — distinguishes a bad token (401) from a Cloudflare block (403/1010)
- `search_recipes(query, limit)`
- `suggest_recipes(foods, limit, max_missing_foods)`
- `get_recipe(slug_or_id)`
- `list_organizers()` — existing categories and tags, so imports reuse the vocabulary
- `find_by_source_url(url)` — duplicate check on `orgURL`
- `scale_ingredients(slug_or_id, servings)`

**Import**
- `import_recipe_url(url, check_duplicates=True)`
- `import_recipe_text(text, source_url=None)`
- `import_recipe_image(image_path)`

Each returns an extraction report flagging `Could not detect ...` placeholders and
campaign junk in the title. A response is not proof of a good import.

**Write**
- `patch_recipe(slug_or_id, patch)`
- `parse_ingredients(slug_or_id)`
- `set_cover_image(slug_or_id, source_url=None, image_path=None)`
- `shopping_list_add(items)`

**Verify**
- `verify_recipe(slug_or_id, image_verified=False, taxonomy_skipped_reason=None)`

Writes are deliberately separate tools so a client can request confirmation.

## `verify_recipe`

The one that keeps the rest honest. It runs the finished-import definition as code
and returns pass/fail per check, so an agent cannot report success on a recipe with an
English ingredient line, a missing cover, or ingredients still in the "Click Parse"
state.

`image_verified` must be passed explicitly by a caller that actually ran an image step.
A non-empty `image` field is only a warning: it does not prove the UI shows a cover.

## Resources

The reference notes ship as MCP resources rather than prompt text:

- `mealie://reference/family-taste-profile`
- `mealie://reference/import-pitfalls`
- `mealie://reference/koket-attribution`
- `mealie://reference/cloudflare-hostname`

## Prompt

`import_pipeline(source)` spells out the order — import → normalize → image → parse →
verify — so no step gets skipped.

## Out of scope

The Obsidian meal plan. That is file writing in a vault and belongs to the client's own
file tools; folding it in would make this server two things at once.

## Tests

```bash
python -m pytest
```

The suite covers the verified failure modes: Cloudflare 1010 vs 401, decimal-comma
normalization, parser-mangled display text, the required `extension` field on uploads,
the 500 on structured ingredient patches, and duplicate detection by `orgURL`.
