{
  "mcpServers": {
    "blockrun-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@blockrun/[email protected]"
      ],
      "env": {
        "BLOCKRUN_WALLET_KEY": "<YOUR_VALUE>",
        "SOLANA_WALLET_KEY": "<YOUR_VALUE>",
        "BLOCKRUN_API_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

BLOCKRUN_WALLET_KEY secret — Optional: EVM private key (0x-prefixed hex) for USDC payments on Base; also the Polymarket signer. If not set, a wallet is auto-generated.
SOLANA_WALLET_KEY secret — Optional: Solana private key (bs58) for USDC payments on Solana. Setting it selects the Solana chain. If not set, a wallet is auto-generated.
BLOCKRUN_API_KEY secret — Optional: BlockRun account API key; bills your prepaid balance instead of a wallet (no per-call network fee). Takes priority over a wallet when set.
