Environment variables
Variables the server reads at startup.
| Name | Required | Description |
|---|---|---|
BLOCKRUN_WALLET_KEYsecret | No | 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_KEYsecret | No | 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_KEYsecret | No | 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. |

About Blockrun MCP
Real-time data — and real trades — for Claude and any AI agent. Agents can pay like agents: sign transactions from a wallet. Teams can pay like teams: get a BlockRun API key at user.blockrun.ai , add credit by card or wire, and let the MCP call api.blockrun.ai . BlockRun MCP gives your agent 19 tools — markets, research, web search, images, video, on-chain data, and live Polymarket trading — paid per call.
