Hedera MCP Server: Model Context Protocol Integration

Overview: What is Hedera MCP Server?

The Hedera MCP Server integrates with a Langchain wrapper to facilitate interactions with the Hedera network through natural language commands, enabling users and AI applications to perform various operations seamlessly. This server serves as an essential bridge between AI applications and the complex world of blockchain technology, making it easier for developers to leverage the powerful functionalities of Hedera within their applications without needing deep technical knowledge.

🔧 Core Features & MCP Capabilities

The core capabilities of the Hedera MCP Server revolve around its seamless integration with the Langchain wrapper. This allows for a wide range of operations such as token creation, HBAR transfers, and smart contract interactions, all initiated via natural language commands. The server's architecture is designed to be flexible and extensible, accommodating future expansions or modifications without significant rewrites.

One key feature is its compatibility with leading MCP clients such as Claude Desktop, Continue, and Cursor, ensuring that the server can support a wide array of AI applications. Additionally, it provides detailed documentation for developers looking to integrate this server into their projects, making it easier for them to understand how to leverage the Model Context Protocol effectively.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Hedera MCP Server is built around a robust set of components that work together to provide seamless and secure interactions with the Langchain wrapper. The primary services are managed in two distinct packages: mcp-server and langchain-proxy, each designed for specific roles.

1. Langchain Proxy Service: This service acts as an intermediary between the MCP server and the Langchain wrapper, handling communication protocols and authentication mechanisms.

2. MCP Server Component: This component is responsible for interpreting user commands and sending them through the Langchain proxy to the appropriate functions in the Hedera network.

The protocol implementation leverages Server-Sent Events (SSE) for maintaining real-time connections between clients and servers, ensuring that data synchronization remains consistent and efficient.

🚀 Getting Started with Installation

To begin using the Hedera MCP Server, follow these steps:

1. Clone the Repository:

   git clone https://github.com/mateuszm-arianelabs/hedera-mcp-server.git
   cd hedera-mcp-server
   

2. Set Up Environment Variables:

   • Copy and create .env files in both packages/langchain-proxy and packages/mcp-server.
   • Edit the .env file with necessary configuration values:

     API_URL=                 # URL to langchain proxy endpoint
     PORT=                    # Port on which mcp server will be started
     MCP_AUTH_TOKEN=          # Array of accepted tokens separated by commas
     LANGCHAIN_PROXY_TOKEN=   # Token for accessing the Langchain proxy
     

3. Install Dependencies:

   pnpm install
   

4. Start Services:

   • Start langchain proxy:

     pnpm run dev:lc  # Or use `pnpm start` in production mode
     

   • Run the mcp server:

     pnpm run dev:mcp  # Or use `pnpm start` in production mode
     

💡 Key Use Cases in AI Workflows

Use Case 1: Token Creation and Management

Imagine a scenario where an AI application needs to create new tokens on the Hedera network. The user would issue a command like, "Create a token called 'HederaUSD' with initial supply of $1000," which is then interpreted by the MCP server and executed via the Langchain proxy.

Use Case 2: HBAR Transfers

In another use case, an AI application might need to transfer values between users. A command such as "Transfer 5 HBAR from Alice's account to Bob's account" would trigger the MCP server to send this request through the Langchain wrapper to perform the actual transaction.

🔌 Integration with MCP Clients

Hedera MCP Server is designed to work seamlessly with popular MCP clients:

• Claude Desktop: Supports full integration, ensuring smooth interaction between AI applications and blockchain services.
• Continue: Also fully supported, offering a robust experience for developers building complex applications.
• Cursor: Partial support due to current limitations in handling specific commands.

MCP Client compatibility ensures a consistent user experience across different tools and platforms.
