Fitatu MCP Unofficial

Fitatu MCP Unofficial

Unofficial Model Context Protocol (MCP) server for accessing and updating data in your own Fitatu account. It provides typed tools for profile data, meal plans, nutrition summaries, food search, and recipe management over stdio or Streamable HTTP.

[!IMPORTANT] This project is not affiliated with, endorsed by, or sponsored by Fitatu. Use it only with your own account and treat Fitatu credentials and account data as sensitive.

Features

• Profile, day-plan, and nutrition summary queries.
• Latest or date-specific body measurement lookup and partial updates for explicit calendar dates.
• Food and recipe search with identifiers required by mutation tools.
• Meal item creation, update, replacement, movement, and removal.
• Recipe creation, inspection, update, and deletion.
• MCP transports for local stdio and Streamable HTTP clients.
• Local development and Docker workflows.

Requirements

• Node.js >=22.18.0
• npm
• A Fitatu account

Docker and ngrok are optional and required only for their respective workflows.

Quick start

Install dependencies and create the local configuration file:

npm install
cp .env.example .env

Set FITATU_EMAIL and FITATU_PASSWORD in .env, then start the development server:

npm run dev

The default MCP endpoint is http://localhost:3000/mcp.

MCP client configuration

Choose one transport with MCP_TRANSPORT:

Transport	Best for	Process model
stdio	A local client that launches its own MCP server	One server process per client
http	A persistent server shared by one or more clients	Long-running server on /mcp

stdio

Build the server before configuring the client:

npm run build

Use absolute paths to the repository's .env and dist/index.js files:

{
	"mcpServers": {
		"fitatu": {
			"command": "node",
			"args": [
				"--env-file=/absolute/path/to/fitatu-mcp-unofficial/.env",
				"/absolute/path/to/fitatu-mcp-unofficial/dist/index.js"
			],
			"env": {
				"MCP_TRANSPORT": "stdio"
			}
		}
	}
}

The client starts and stops the server. In stdio mode, logs are written to stderr because stdout is reserved for the JSON-RPC stream.

Streamable HTTP

Start the server with npm run dev, or build and run it with:

npm run build
npm start

Clients with native Streamable HTTP support can connect directly to:

http://localhost:3000/mcp

For a client that launches remote MCP connections through a command, use mcp-remote:

{
	"mcpServers": {
		"fitatu": {
			"command": "npx",
			"args": ["mcp-remote", "http://localhost:3000/mcp"]
		}
	}
}

To inspect the local server interactively:

npm run inspector

Connect the Inspector to http://localhost:3000/mcp.

Remote MCP access with ngrok

Install and authenticate ngrok. In .env, configure two different Fitatu accounts using FITATU_* and FITATU_INTEGRATION_*, then add your assigned domain:

NGROK_DOMAIN=your-assigned-domain.ngrok-free.dev

npm run dev:all           # Both accounts and the tunnel
npm run dev:test-account # Test account only (alternative)

In any MCP client that supports remote Streamable HTTP connections, use one of these URLs without authentication:

• Personal: https://YOUR_NGROK_DOMAIN/personal/mcp
• Test: https://YOUR_NGROK_DOMAIN/test/mcp

Addresses stay the same after restarting. Keep the command running; Ctrl+C stops everything. Optional port settings are in .env.example.

Anyone with the URL can access that account while the tunnel runs. Use it only for temporary development sessions.

Available tools

Tool	Purpose
get_current_user	Return a safe subset of the authenticated user profile.
get_body_measurement	Return the latest body measurement, or the complete entry for an optional YYYY-MM-DD date.
save_body_measurement	Partially update body measurements for a YYYY-MM-DD date using profile units.
get_user_settings	Return date-resolved energy, calculated, and water settings with requested and effective dates; date defaults to today in the Fitatu timezone.
update_user_settings	Set a manual or automatic energy target, update the water serving size, or apply both changes together.
get_day_plan_items	Return meals and food items for a YYYY-MM-DD date.
get_diet_summary	Summarize nutrition and energy for an inclusive date range.
search_food	Search Fitatu food catalogs and return mutation-ready identifiers.
search_food_by_barcodes	Search the public food catalog for up to 10 barcodes in parallel.
add_meal_items	Add products, recipes, or custom items to a meal.
update_meal_item	Update quantity, measure, or eaten state.
replace_meal_item	Replace one exact meal entry.
move_meal_item	Move an item to another meal, date, or both.
remove_meal_items	Atomically remove selected day-plan entries by UUID.
search_recipes	Search private recipes, public recipes, or both catalogs.
get_recipe	Return canonical per-serving recipe details.
create_recipe	Create a private recipe from product and measure identifiers.
update_recipe	Partially update an owned, editable recipe.
delete_recipe	Soft-delete a recipe after exact-name confirmation.

Configuration

Runtime configuration is read from environment variables and validated at startup.

Variable	Required	Default	Description
FITATU_EMAIL	Yes	—	Fitatu account email address.
FITATU_PASSWORD	Yes	—	Fitatu account password.
FITATU_INTEGRATION_EMAIL	For integration tests and tunnel commands	—	Email address of a dedicated Fitatu test account.
FITATU_INTEGRATION_PASSWORD	For integration tests and tunnel commands	—	Password for the dedicated Fitatu test account.
MCP_TRANSPORT	No	http	MCP transport: http or stdio.
PORT	No	3000	HTTP port; unused in stdio mode.
HOST	No	0.0.0.0	HTTP bind address; unused in stdio mode. The tunnel launcher forces loopback.
NODE_ENV	No	development	development, production, or test.
SERVER_NAME	No	fitatu-mcp	Name reported by the MCP server.
SERVER_VERSION	No	3.0.0	Version reported by the MCP server.
LOG_LEVEL	No	info	silent, error, warn, info, or debug.
FITATU_USER_AGENT	No	Dart/3.10 (dart:io)	Fitatu mobile runtime user agent.
FITATU_APP_VERSION	No	4.14.4	Fitatu mobile application version.
FITATU_API_APK_UUID	No	BE4B.251210.005	Fitatu mobile build identifier.

Do not commit .env. The mobile client profile defaults match Fitatu 4.14.4 traffic captured on 2026-07-30 and can be overridden without changing code.

Docker

The current image build requires a configured .env file:

cp .env.example .env
docker build -t fitatu-mcp .
docker run --name fitatu-mcp -p 3000:3000 fitatu-mcp

The Dockerfile copies .env into the image. Treat the resulting image as sensitive; do not publish or share it.

Development

Task	Command
Development server	npm run dev
Both accounts with ngrok	npm run dev:all
Test account with ngrok	npm run dev:test-account
Production build	npm run build
Start built server	npm start
Type checking	npm run typecheck
Lint	npm run lint
Formatting check	npm run format:check
Unit tests with coverage	npm run test:ci
Local coverage report	npm run test:coverage
Integration tests	npm run test:integration

npm run test:ci is deterministic and does not load Fitatu credentials. Integration tests use the dedicated Fitatu test account described above and may mutate its meal-plan, recipe, and body-measurement data.
