The Hedera MCP Server is a modular Node.js server designed for decentralized communication between AI agents on the Hedera network, implementing the Model-Context-Protocol (MCP) architecture.
The Hedera MCP Server is a production-ready, modular Node.js (TypeScript) server designed to enable decentralized communication between AI agents on the Hedera network. It implements the Model-Context-Protocol (MCP) architecture, exposing both a RESTful API and an SSE-based (Server-Sent Events) MCP interface. Using the Hedera Agent Kit alongside the Standards Agent Kit, the server supports multiple Hedera Consensus Service (HCS) standards, including HCS-1 for file/data management, HCS-2 for agent discovery, HCS-3 for large message handling, HCS-10 for agent communication, and HCS-11 for decentralized identity management. This server is aimed at developers building AI-integrated decentralized applications on Hedera and is compatible with tools like Cursor for autonomous agent interactions.
Features
- Agent Registration & Profiles (HCS-11): Create new Hedera accounts for AI agents, automatically setting up inbound/outbound topics and on-chain profiles.
- Agent Discovery (HCS-2): Register agents in a centralized registry topic and discover agents by name or capability using the search API.
- Secure Communication (HCS-10): Initiate and accept connection requests between agents, establishing dedicated connection topics for secure message exchange.
- Large Message Handling (HCS-1 & HCS-3): Offload large message content by storing it on dedicated file topics and returning an HRL reference within messages.
- MCP Interface via SSE: Expose an MCP-compliant SSE endpoint that lets AI tools like Cursor directly invoke server tools.
