Composio MCP Server: Universal Adapter for AI Applications

Overview: What is Composio MCP Server?

The Composio MCP Server is an implementation of the Model Context Protocol (MCP), designed to facilitate seamless integration between AI applications and various Composio tools and applications such as Gmail, Linear, and more. This server acts as a bridge, enabling AI models like Claude Desktop, Continue, Cursor, and others to interact with these tools through a standardized interface defined by MCP. By leveraging this protocol, developers and AI application creators can access rich functionality provided by Composio tools directly from their AI applications, enhancing their capabilities.

🔧 Core Features & MCP Capabilities

The Composio MCP Server offers several key features that make it indispensable for developers working with AI applications:

1. Standardized Interface: The server adheres to the Model Context Protocol (MCP), ensuring compatibility across a wide range of AI clients.
2. Rich Tool Integration: It allows integration with diverse tools and services like Gmail, Linear, Slack, and more, providing access to a broad array of functionalities for AI applications.
3. Enhanced Functionality: By exposing Composio tools through MCP, the server enhances the functionality of AI applications, making them more versatile and useful in various workflows.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Composio MCP Server is designed to be modular and flexible. It includes several key components that together enable seamless communication between AI clients and the underlying tools:

1. MCP Client: Each AI application acts as a client, initiating requests through the MCP protocol.
2. MCP Protocol Handler: This component processes incoming requests from the AI client, translating them into actions on Composio tools and services.
3. Tool Adapter Layer: Custom adapters are implemented for each tool (e.g., Gmail, Linear), handling specific interactions and data exchanges.

🚀 Getting Started with Installation

To get started, follow these steps to install and configure the Composio MCP Server:

1. Clone the Repository:

   git clone https://github.com/composio/composio-mcp-server.git
   cd composio-mcp-server
   

2. Install Dependencies and Build the Project:

   pnpm install && pnppm build
   

3. Configure for Composer Integration:

   • Open Cursor Settings

   • Navigate to Features -> Add MCP Server

   • Add the following command:

     COMPOSIO_API_KEY=<composio_api_key> node /path/to/composio-mcp-server/build/index.js
     

   • Replace /path/to/composio-mcp-server with the actual path where you cloned the repository

   • Replace <composio_api_key> with your actual Composio API Key

💡 Key Use Cases in AI Workflows

1. Email Management: Integrate Gmail tools to manage emails, automate tasks, and retrieve data directly from the AI application.
2. Task Automation: Automate task creation, tracking, and management using Linear or other Project Management tools integrated through MCP.

Real-World Implementation Example 1: Email Automation with Composio MCP Server

In this scenario, an AI application leverages the Composio MCP Server to interact with Gmail for email automation tasks. The AI model can send emails, retrieve inbox messages, and manage email threads directly from its interface by invoking specific MCP commands.

def send_email(subject, body, recipient):
    mcp_send_command("/gmail/send", {"subject": subject, "body": body, "to": recipient})

Real-World Implementation Example 2: Task Management with Composio Linear

This example demonstrates how the Composio MCP Server can be used to integrate Linear for task management within an AI application. The AI model can create tasks, update their status, and retrieve task details through the exposed Linear API.

def create_task(title, description):
    mcp_send_command("/linear/create", {"title": title, "description": description})

🔌 Integration with MCP Clients

The Composio MCP Server is compatible with several popular MCP clients:

• Claude Desktop (Full Support)
• Continue (Full Support)
• Cursor (Tools Only)
