Source: https://cotlet.dev/docs/mcp/fitatu/log_food

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Add a product or meal from the database to a meal on a day.

Fitatu MCP tools: https://cotlet.dev/docs/mcp/fitatu.md

MCP tool: `fitatu_write → log_food`

Access: write.

Adds one product or meal from search_food to the chosen meal and day, in grams, milliliters or a handy measure the product offers, such as a slice or a package. It reaches no one and is undone with one call, delete_diary_item, so it runs without asking first.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `food_id` | string | yes | Product or meal ID from search_food. |
| `meal` | string | yes | Meal name from your Fitatu meal scheme. By default: breakfast, second breakfast, lunch, dinner, snack or supper. |
| `amount` | number | yes | How much, in the unit below. |
| `unit` | string | yes | gram, milliliter or a measure the product lists, e.g. slice, teaspoon, handful or package. |
| `date` | date | no | Day to log on, YYYY-MM-DD. Default: today. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
