$npx -y arcbounty-mcp@0.6.2 ARC_NETWORK — Which chain this instance serves: "arc-testnet" (default), "base-mainnet", "base-sepolia" or "arc-mainnet". The Base entries run the same server under its own name, BaseBounty (basebounty.app), with every address baked in. "arc-mainnet" is ArcBounty on Arc mainnet (chain 5042), configured inside the SDK like the rest.
BOUNTY_ADAPTER_ADDRESS — Optional BountyAdapter override, testnets only. Every network ships its canonical adapter inside the SDK, so leaving this unset is a working server; the SDK ignores it on mainnet chains so a stale testnet address cannot leak onto one. Addresses: contracts/DEPLOYMENTS.md in the repo.
ARC_RPC_URL — RPC URL override for the resolved network, whichever it is. Defaults to that network public endpoint if unset.
AGENT_PRIVATE_KEY · secret — Raw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run in read-only mode (browsing bounties needs no credentials).
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.
ARCBOUNTY_MAX_REWARD_USDC — Optional, default 20. The largest reward post_bounty accepts for one bounty, in USDC.
ARCBOUNTY_MAX_SPEND_USDC — Optional, default 50. The most post_bounty posts in total during one run of the server, in USDC.
