Renders custom Jinja report templates against recipes or menus via the render_report tool; agents can author and save .jinja templates under reports/ or config/reports/ with write_config, and templates can include nutrition functions when logged in. Plain templates need no login.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@cook-mcp build a shopping list for this week's menu, minus my pantry"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server that gives your AI agent (Claude Code, Claude Desktop, Cursor, ChatGPT, or any other MCP client) access to your Cooklang recipe collection. Recipes stay as plain .cook and .menu files in a folder you own. The agent can read, search, validate and write them, build shopping lists, track a pantry and render reports, all locally and without an account. With a cook.md login it can also compute nutrition and import recipes from photos and social links.
Claude Code:
claude mcp add cook -- npx -y @cookmd/mcpAny client that takes an mcpServers config:
{
"mcpServers": {
"cook": {
"command": "npx",
"args": ["-y", "@cookmd/mcp"],
"env": { "COOK_RECIPES_DIR": "/path/to/recipes" }
}
}
}If COOK_RECIPES_DIR is not set, the server uses the workspace folder your client shares, or the folder the client was started in. See How the recipe folder is chosen.
Supported platforms: macOS (arm64, x64) and Linux (x64, arm64, glibc 2.35 or newer). There are no Windows builds yet.

Claude Code users can install the cooklang plugin instead of adding the server by hand. It lives in cooklang/cooklang-skills and bundles this server plus the skills below:
/plugin marketplace add cooklang/cooklang-skills
/plugin install cooklang@cooklang-skillsThe plugin starts the server with your Claude Code project folder as the recipe root, and Claude Code picks the right skill from what you ask ("plan dinners for next week", "is this recipe valid?"). If you already added the server with claude mcp add cook, remove that entry so you don't run two copies.
The skills (also served by this server as cooklang://skills/<name> resources):
Skill | Use it for |
| Write a new recipe or edit and fix a |
| Check recipes, a folder or the whole collection for errors and broken references |
| Add or fix YAML frontmatter (title, tags, servings, times), including bulk changes |
| Import a recipe from a URL, photos or pasted text |
| Find recipes by ingredient, tag, cuisine, course or a remembered phrase |
| Show a recipe for more or fewer servings |
| Turn a recipe into Markdown, JSON, plain text or HTML |
| Folder layout, metadata audit, aisle and pantry config, whole-library checks |
| Build or edit a |
| Shopping lists from recipes or plans, grouped by aisle, minus the pantry |
| Track stock, expiry and low items; what can I cook with what I have |
| Custom Jinja reports and printouts with |
| Nutrition evaluation and screening (Cook Basic or Pro) |
| Change a recipe or plan to hit nutrition targets (Cook Basic or Pro) |
skills/ in this repo is the canonical copy; the plugin repo syncs from it. Each skill is skills/<name>/SKILL.md.
Tool | What it does |
| List recipes, meal plans or report templates ( |
| Read a recipe or menu: source plus parsed ingredients, cookware, steps and metadata; optional scaling |
| Search names and contents, optionally filtered by tag |
| Check a file, a folder, the whole collection, or unsaved content for errors and broken references |
| Save a |
| Save a |
| Save |
| Build a shopping list from recipes and/or menus: merges duplicates, groups by aisle, subtracts the pantry |
| Show the pantry, by section |
| Items expiring soon |
| Items at or below their low-stock threshold |
| Which recipes you can cook with what is in the pantry |
| Add, update or remove pantry items |
| Render a jinja report template against a recipe or menu (plain templates need no login) |
Tool | What it does |
| Start a cook.md device login; shows a code and a URL |
| Show login status, plan and import allowance |
| Nutrition facts for one ingredient amount |
| Sum nutrition across many ingredient lines |
| Fuzzy-search the ingredient catalog |
| Convert between units (volume to mass needs a density) |
| Check whether an ingredient belongs to a category |
| Look up a packaged product by barcode or text |
| Daily reference-intake tables (RDA/DV) |
| Convert a web page, photos or pasted text to Cooklang |
import_recipe from a web page or pasted text works without a login. Photos and social-media links need a cook.md account and use your import allowance. It returns Cooklang text and does not save it; the agent validates it and calls write_recipe. Nutrition functions inside render_report also need Cook Basic or Pro.

Writes stay inside the recipe root. Paths outside it are refused.
Every write is validated first; invalid Cooklang is not saved.
The deprecated >> metadata syntax is refused. Use YAML frontmatter.
There is no delete tool. The agent cannot remove your files.
Pantry subtraction in shopping lists only works when units match. For example, 1 kg in the pantry does not cancel 200 g in a recipe. This is a limitation of cookcli-core.
Symlinks inside the recipe folder are mostly not followed for reads and listing. A symlink requested by bare name without an extension, or reached through a recipe's @./ reference, may still be followed. This only matters if you put symlinks pointing outside the folder into your recipes.
No Windows builds yet.
No delete tool.

COOK_RECIPES_DIR, if set. Nothing else is consulted.
The client's MCP roots. If the client supports roots (it shares its open workspace folders with the server), the first file:// root that is an existing folder becomes the recipe root. The server asks on the first recipe tool call and again whenever the client reports that its roots changed. If the client doesn't answer within 5 seconds, the server uses the working directory and asks again later (at most once every 30 seconds).
The folder the client started the server in.
A root is a folder you opened on purpose, so it is used unless it is /, your home folder or inside an agent plugin install folder (for example ~/.codex/plugins/cache/..., ~/.gemini/extensions/... or the folder CLAUDE_PLUGIN_ROOT points to). The working directory is checked more strictly: it is also refused when it, or a folder up to four levels above it, has .claude-plugin/plugin.json, an Agent Plugins plugin.json or gemini-extension.json, because a plugin that starts the server in its own install folder would otherwise expose the wrong files and write recipes into a folder that is wiped on update. When nothing usable is found, recipe tools say that no recipe folder is set, why, and that COOK_RECIPES_DIR fixes it; auth_status shows recipe_root_source: "unset". Otherwise recipe_root_source is env, roots or cwd.
What each client does:
Claude Code sends its project folder as a root (verified), so nothing to configure.
Codex sends no roots (verified with 0.160.1) and may start the server in a plugin folder, so set COOK_RECIPES_DIR:
codex mcp add cook --env COOK_RECIPES_DIR=/path/to/recipes -- npx -y @cookmd/mcpVS Code and Cursor document support for roots (not verified here). If recipe tools say no folder is set, set COOK_RECIPES_DIR in the server's config.
"Plan dinners for next week from my recipes and make the shopping list."
"What can I cook with what's in my pantry?"
"Check my whole collection for broken references."
"Import https://example.com/some-recipe as a recipe."
"How much protein is in this week's plan?" (needs Cook Basic or Pro)
cargo build --release
cargo testThe binary is target/release/cook-mcp. It speaks MCP over stdio. cook-mcp login and cook-mcp logout manage the cook.md login from a terminal.
@cookmd/nutrition-mcp keeps working: it is now a thin shim that runs @cookmd/mcp. To switch, change the package name in your MCP config to @cookmd/mcp. Your login carries over.
Two things changed. Recipe tools need COOK_RECIPES_DIR (old configs did not set it), or start the client in your recipe folder; without either, recipe tools tell the agent that no recipe folder is set. And render_report paths are now relative to the recipe folder.

Scraps Kitchen gives any AI agent a persistent, household-aware kitchen memory. Unlike generic chatbot recall, Scraps maintains structured cooking data: what's in your fridge (with freshness tracking), who you cook for (with allergens, dietary restrictions, and preferences), your recipe collection (with cook notes and per-diner ratings), your shopping list, and your kitchen equipment. 27 tools across 6 domains let agents read kitchen context, suggest meals that respect dietary safety, update the pantry after cooking, and build a history of what works for your household. Every interaction makes the data richer. Cooking history, preference signals, kitchen awareness = better suggestions next time. All tools work via oAuth and a free scraps.kitchen account.
Search, save, organize, cook, and share recipes with any AI assistant.
Your kitchen in chat: pantry stock, shopping lists, recipes and scanned grocery receipts.
Search, read, and edit your Halite recipe collection and shopping lists.
