Convert cups, tablespoons and grams per ingredient, with a real density table and friendly fractions. convert_ingredient turns an amount of a named ingredient between cups, tablespoons, teaspoons, milliliters, fluid ounces, grams and ounces using a per-ingredient density table; scale_recipe doubles or halves a list of recipe lines into friendly fractions; convert_bulk converts many amounts at once and reports unknown ingredients per item; decimal_to_fraction and fraction_to_decimal handle the 1 1/2 cup style; common_conversions lists the most-googled conversions; list_ingredients dumps the table with sources.
You are in a chat window, not a kitchen, so the grams come back as a small table you can paste into the recipe you are already editing, with the density assumption stated.
| You say | Tool |
|---|---|
| How many grams is 1 cup of all-purpose flour? | convert_ingredient |
| Double this recipe: 1 1/2 cups flour, 1/2 cup sugar, 100 g butter. | scale_recipe |
| Convert 250 g butter and 120 ml honey to cups. | convert_bulk |
The contract suite walks a real stdio case through the density table: 1 cup of all-purpose flour comes back as 125 grams with cups, tablespoons and ounces alongside, unknown ingredients are refused with a reason, and nothing hangs.
https://mcp.zovo.one/mcp/connect mints an anonymous token and prints a URL per server, including this one, shaped like https://mcp.zovo.one/mcp/ingredient-convert/t/<token>. That URL works with no headers: the token is in the path, not in an Authorization field this form does not have.
Idle anonymous tokens are swept after 30 days. Since this route has no filesystem, a file MCP Ingredient Converter generates comes back as a download link that expires after one hour. A Pro key can replace the token in the same URL and removes the free-tier limits.
On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.
Free: Everything: seven tools, the full density table, no metering, no key. Pro is $19 once, verified offline, and binds to the token after checkout.
No. Add custom connector offers an Advanced settings section with an OAuth Client ID and Client Secret, but the connect-by-URL route does not use it. Leave both blank: the token in the URL path is what authenticates.
That is documented, not a bug: on Team and Enterprise, only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, Add, Custom, Web. After that, members connect to the URL the Owner added from Customize, Connectors.
Yes. The token segment of the URL from /mcp/connect can be replaced with a Pro key, which removes the free-tier limits on MCP Ingredient Converter for that connector.
The connector runs server-side with no filesystem of its own, so any file MCP Ingredient Converter produces is handed back as a download link that expires after one hour, rather than a path on disk.
