Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`ARC_NETWORK` Optional	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 th…
`BOUNTY_ADAPTER_ADDRESS` Optional	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` Optional	RPC URL override for the resolved network, whichever it is. Defaults to that network public endpoint if unset.
`AGENT_PRIVATE_KEY` Optional, 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` Optional, secret	Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process.
`ENTITY_SECRET` Optional, secret	Circle Developer-Controlled Wallet entity secret.
`CIRCLE_WALLET_ID` Optional	Circle Developer-Controlled Wallet ID.
`CIRCLE_WALLET_ADDRESS` Optional	Circle Developer-Controlled Wallet address.
`ARCBOUNTY_MAX_REWARD_USDC` Optional	Optional, default 20. The largest reward post_bounty accepts for one bounty, in USDC.
`ARCBOUNTY_MAX_SPEND_USDC` Optional	Optional, default 50. The most post_bounty posts in total during one run of the server, in USDC.
