概要

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

よくある質問

1

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.

2

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.

3

What transport protocol does the MCP server use?

It uses Server-Sent Events (SSE) as the transport (endpoint: `/sse`).

4

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.

5

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.
