What is the architecture of Hedera MCP Server?
It consists of two services: a Langchain proxy that interprets natural language requests, and an MCP server that provides the MCP interface and routes to the proxy.

What is Hedera MCP Server?
It integrates a Langchain wrapper to interact with the Hedera network, allowing users to perform Hedera operations through natural language commands. Designed for developers building LLM-powered applications that need to create tokens, transfer HBAR, or interact with smart contracts.
How to use Hedera MCP Server?
Clone the repository, set environment variables in packages/langchain-proxy and packages/mcp-server, then run pnpm install. Start the Langchain proxy service with pnpm run dev:lc, then start the MCP server with pnpm run dev:mcp. Configure the client to connect via SSE at the server’s URL, providing the X-MCP-AUTH-TOKEN header with a token listed in MCP_AUTH_TOKEN.
Key features of Hedera MCP Server
- Perform Hedera operations via natural language commands
- SSE transport with token-based authentication
- Supports token creation, HBAR transfers, smart contract interaction
- Two-service architecture: Langchain proxy and MCP server
- Configurable via environment variables
Use cases of Hedera MCP Server
- Build LLM apps that manage Hedera accounts and tokens
- Automate Hedera operations through conversational interfaces
- Integrate Hedera functionality into AI assistants
- Prototype decentralized applications with natural language queries
常见问题
How does authentication work?
The MCP server requires an `X-MCP-AUTH-TOKEN` header with a value matching one of the tokens listed in the `MCP_AUTH_TOKEN` environment variable.
What transport protocol does the MCP server use?
It uses Server-Sent Events (SSE) as the transport (endpoint: `/sse`).
What are the runtime requirements?
Node.js version 20 or later, the `pnpm` package manager, and Git. Environment variables must be configured in two package directories.
Are there any known limitations with client IDEs?
Custom HTTP headers (such as `X-MCP-AUTH-TOKEN`) are not currently supported in Cursor IDE, though support is expected in future versions.
