Hedera Ecosystem MCP Servers

April 16, 2026 ยท View on GitHub

The Hedera Agent Kit provides easy access to MCP servers hosted by affiliated ecosystem partners. These servers extend your agent's capabilities with specialized tools for network interaction, data indexing, and more.

Note

These services are provided by third-party partners and are not directly managed by the Hedera Agent Kit team.

Configuration

These servers are preconfigured in the HederaMCPServer enum and can be loaded directly into your agent configuration:

import { HederaLangchainToolkit, HederaMCPServer } from '@hashgraph/hedera-agent-kit-langchain';

const toolkit = new HederaLangchainToolkit({
  configuration: {
    // ...
    mcpServers: [
      HederaMCPServer.HEDERION_MCP_MAINNET,
      // or
      HederaMCPServer.HGRAPH_MCP_MAINNET
    ]
  }
});

// Explicitly fetch tools from the configured MCP servers
const mcpTools = await toolkit.getMcpTools();

Examples

You can find complete working examples of how to use preconfigured MCP clients in the following files:

Note

MCP tool support is only available for LangChain v1 and Vercel AI SDK. Legacy LangChain (Classic) is not supported.

In these examples, notice that getMcpTools() matches the pattern shown above. This explicit fetching ensures that external tools are strictly loaded only when requested, preventing initialization race conditions.
