dgb-chain-mcp

Let any AI agent query DigiByte directly. An MCP server that exposes live DigiByte blockchain data as tools an agent can call: network health, DigiDollar stats, oracle status, prices, address balances, transactions, blocks.

Ask Claude "what's DigiByte's DigiDollar supply?" or "is oracle 29 reporting?" or "what's the DGB/USD price?" — and it answers from the live chain, not from stale training data.

Read-only. No wallet, no keys, nothing is ever sent. Because it only reads public blockchain data, it is safe to point at a mainnet node — and that's where it's most useful, since the data is real.

Why this exists

The goal is the one an old comparison-content website ("DGB Insights") reached for and missed: give AI good information about DigiByte. The website was the wrong shape — content sitting on a page hoping to get crawled. This is the right shape: a tool an agent calls and gets an authoritative, live answer from.

Tools

Setup

Point it at any DigiByte node (v8+; DigiDollar tools need v9.26.4+ with DigiDollar active). The node needs txindex=1 for get_transaction on arbitrary txids.

npm install
cp .env.example .env    # your node's RPC url / user / password

Then add it to your MCP client (Claude Desktop / Claude Code):

{
  "mcpServers": {
    "dgb-chain": {
      "command": "node",
      "args": ["/absolute/path/to/dgb-chain-mcp/src/server.js"],
      "env": {
        "DGB_RPC_URL": "http://127.0.0.1:14022",
        "DGB_RPC_USER": "your-rpc-user",
        "DGB_RPC_PASSWORD": "your-rpc-password"
      }
    }
  }
}

(Mainnet RPC is usually :14022; testnet :14023/:14026 depending on config.)
