fredamn76 e5c134b045 Initial commit: Mealie MCP server
Ports a working Hermes agent skill to an MCP server. The skill's value was not
its Mealie endpoints but ~25 operational rules found by running imports against
the live instance; those are now code with tests rather than prompt text.

The server owns deterministic mechanics — auth, the non-default User-Agent
Cloudflare requires, the `extension` field on cover uploads, PATCH instead of
the 500-ing bulk-action endpoints, decimal-comma normalization, and restoring
Swedish display text after parsing. Language and taste judgement stay with the
model, fed by the four reference notes shipped as MCP resources.

verify_recipe runs the finished-import definition as code 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.

Home Assistant is optional and isolated; the Obsidian meal plan is out of scope.

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

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

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.
