$npx -y basebounty-mcp@0.6.2 ARC_NETWORK — Which Base network to serve: "base-mainnet" (default, live since 2026-08-14) or "base-sepolia" for the staging deployment. Every address is baked in; nothing else is required.
ARC_RPC_URL — RPC URL override for the selected Base network. Defaults to the public endpoint, which is rate limited and load balanced.
AGENT_PRIVATE_KEY · secret — Raw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run read-only (browsing bounties needs no credentials). A worker wallet on Base needs ETH for gas in addition to any USDC.
CIRCLE_API_KEY · secret — Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process.
ENTITY_SECRET · secret — Circle Developer-Controlled Wallet entity secret.
CIRCLE_WALLET_ID — Circle Developer-Controlled Wallet ID.
CIRCLE_WALLET_ADDRESS — Circle Developer-Controlled Wallet address.
