What credentials are required?

You need a TATUM_API_KEY obtained from the Tatum MCP page or dashboard.

Which clients are shown in the setup instructions?

The README provides setup examples for Cursor and Claude Desktop.

Can it execute blockchain transactions?

The documented gateway tool runs JSON-RPC methods or REST calls, while the listed data tools query blockchain information. Transaction submission is not documented.

Documentation Overview

Blockchain MCP powered by Tatum

A Model Context Protocol (MCP) server that exposes the Tatum Blockchain Data API and RPC Gateway so LLM clients can query blockchain data across 130+ networks. Get an API key on the Tatum MCP page or dashboard.

Features

130+ Blockchain Networks: Bitcoin, Ethereum, Solana, Polygon, Arbitrum, Base, Avalanche, and many more.
🔗 Blockchain Data API: Blocks, transactions, balances, network info, and more.
🌐 RPC Gateway: Direct access to blockchain RPC endpoints.

Requires Node.js 18+ and a TATUM_API_KEY.

Installation

Terminal

npm install -g @tatumio/blockchain-mcp

Or use without a global install:

Terminal

npx @tatumio/blockchain-mcp

Published binaries: blockchain-mcp and blockchain-mcp-server (same entrypoint).

MCP client setup

Create a free API key at dashboard.tatum.io.
Add the server to your MCP client (Cursor, Claude Desktop, VS Code, etc.):

config.json

{
  "mcpServers": {
    "tatumio": {
      "command": "npx",
      "args": ["@tatumio/blockchain-mcp"],
      "env": {
        "TATUM_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Do not commit API keys. Use environment variables in client config only.

Example prompts

Once connected, you can ask your assistant to use MCP tools, for example:

“What is the BTC/USD exchange rate?” → get_exchange_rate with symbol: BTC, basePair: USD
“Show Vitalik’s native ETH balance history” → get_wallet_portfolio / get_transaction_history on ethereum-mainnet
“What is the latest Ethereum block number?” → gateway_execute_rpc with eth_blockNumber

Chain identifiers use Tatum gateway names (e.g. ethereum-mainnet, bitcoin-mainnet). Call gateway_get_supported_chains for the live list.

Development

bash

git clone https://github.com/tatumio/blockchain-mcp.git
cd blockchain-mcp
npm install
cp .env.example .env   # add your TATUM_API_KEY
npm run build

Run the MCP server locally:

server.ts

export TATUM_API_KEY=your-key
npm start
# or via CLI wrapper:
npx blockchain-mcp --api-key your-key

Point a local MCP client at the built CLI:

config.json

{
  "mcpServers": {
    "tatumio-local": {
      "command": "node",
      "args": ["/absolute/path/to/blockchain-mcp/dist/cli.js"],
      "env": { "TATUM_API_KEY": "YOUR_API_KEY" }
    }
  }
}
