Install Hedera in Claude Code, Cursor or VS Code

Runs npx -y @purplesquirrel/hedera-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Hedera repository's README, as published. We do not edit it. Read it on GitHub

hedera-mcp

Comprehensive Model Context Protocol server for Hedera (Hashgraph). Full coverage of every core Hedera service — Account, Token (HTS), Consensus (HCS), Smart Contract (EVM), File, Schedule, and Network — exposed as 73 MCP tools any AI agent (Claude, Cursor, etc.) can call.

Build-only. Never holds keys. Reads hit the public Mirror Node REST API (no auth). Writes return an unsigned, frozen transaction (base64) for you to sign and submit with your own wallet/SDK/CLI. This server never sees a private key and never executes anything.

Why this exists

The official Hedera Agent Kit ships a preconfigured MCP server, but its tool surface is intentionally small (balance, transfer, deploy). This server fills the gap with end-to-end coverage of the Hedera API, organized for developer education and agent-driven onboarding — so a developer can go from "certified" to "shipping their first HTS token / HCS topic / contract" inside a single AI session.

Security model

  • Reads → public Mirror Node REST. No keys, no account required.
  • Writes → the tool constructs the transaction, freezes it for offline signing, and returns base64 bytes plus a human summary. You inspect it (hederadecodetransaction), then sign and submit yourself.
  • The only optional environment input is HEDERAOPERATORID — an account id, used as the default payer/treasury when building. Never a key.

This mirrors the posture of goat-network-mcp: safe to run anywhere, safe to give to an autonomous agent.

Published on npm and the MCP Registry as io.github.ExpertVagabond/hedera-mcp.

Install

Run directly with npx (no clone needed):

npx @purplesquirrel/hedera-mcp

Or from source:

npm install
npm run build

Configure (Claude Desktop / Claude Code)

{
  "mcpServers": {
    "hedera": {
      "command": "npx",
      "args": ["-y", "@purplesquirrel/hedera-mcp"],
      "env": {
        "HEDERA_NETWORK": "testnet",
        "HEDERA_OPERATOR_ID": "0.0.1234"
      }
    }
  }

Build-only workflow

agent calls hedera_create_fungible_token
        │
        ▼
hedera-mcp builds + freezes the TokenCreateTransaction
        │
        ▼
returns base64 (unsigned)  ──►  you sign in HashPack / SDK / CLI  ──►  submit to Hedera

Inspect anything before signing:

hedera_decode_transaction { transactionBase64: "<bytes>" }
→ { type: "TokenCreateTransaction", transactionId, nodeAccountIds, maxTransactionFee, ... }
