​
Overview

The Apps MCP Server provides direct access to functions (tools) from specific app(s) you select. Unlike most MCP servers that are bound to a single app, this server allows you to combine multiple apps in one server.

​
Benefits

  • Multi-App Support - Include functions from multiple apps in a single MCP server
  • Direct Function Access - Functions appear directly in the LLM’s tool list without discovery steps (Which usually have better performance if your usecase is very specific)
  • Selective Inclusion - Only include the Apps whose functions you want to expose
  • Reduced Server Management - No need to run multiple MCP servers for different apps
  • Familiar Pattern - Similar to traditional MCP server concept but with multi-app capability

​
How It Works

The Apps MCP Server directly exposes the functions (tools) from the apps you specify with the --apps parameter. When an MCP client interacts with this server, all functions from the specified apps will be available in its tool list.

This approach differs from the Unified MCP Server in that there’s no dynamic discovery process - all function (tool) definitions are directly available to MCP clients.

Unlike most MCP servers that are limited to a single app, the Apps MCP Server allows you to combine functions from multiple apps in a single server, reducing the number of servers you need to manage.

​
Prerequisites

Before using the Apps MCP Server, you need to complete several setup steps on the ACI.dev platform.

1

Get your ACI.dev API Key

You’ll need an API key from one of your ACI.dev agents. Find this in your project settings

2

Configure Apps

Navigate to the App Store to configure the apps you want to use with your MCP servers.

For more details on what is an app and how to configure it, please refer to the App section.

3

Set Allowed Apps

In your Project Settings , enable the apps you want your agent to access by adding them to the Allowed Apps list.

For more details on how and why to set allowed apps, please refer to the Agent section.

4

Link Accounts For Each App

For each app you want to use, you’ll need to link end-user (or your own) accounts. During account linking, you’ll specify a linked-account-owner-id which you’ll later provide when starting the MCP servers.

For more details on how to link accounts and what linked-account-owner-id is, please refer to the Linked Accounts section.

Install the Package

# Install uv if you don't have it already
curl -sSf https://install.pypa.io/get-pip.py | python3 -
pip install uv
