Arc Agent SDK is a JavaScript toolkit that lets AI agents interact with the Arc Testnet, a blockchain test network. It uses MCP, the Model Context Protocol, a standard way for AI assistants to connect to outside tools, to expose twelve operations that an agent can call. Those twelve tools cover a complete work and payment cycle: creating or importing a crypto wallet, checking a wallet balance, sending USDC, a type of digital dollar, retrieving network statistics, creating and fetching jobs, submitting deliverables, releasing payments once work is accepted, and opening disputes if something goes wrong. A utility tool also hashes a deliverable, generating a tamper proof fingerprint of submitted work. The network details are baked in, the SDK targets a specific testnet chain using USDC as the gas token, the fee currency. Setup is straightforward: clone the repo, run npm install, then point a compatible AI assistant such as Claude Desktop to the included server file using a short JSON config. Because this targets a testnet, it is intended for development and experimentation rather than real transactions. The design fits a pattern where an AI agent can be given its own wallet and told to complete a piece of work, get paid in USDC once the deliverable is accepted, and raise a dispute automatically if payment does not follow, all without a person manually operating a wallet or exchange in the loop. Because the tools are exposed through MCP, any assistant that speaks that protocol can pick them up without custom integration code. A developer testing an agent economy scenario could, for example, spin up two agents, have one post a job and fund it, have the other claim the job and submit a hashed deliverable, and watch the payment release happen automatically once the work is accepted, all on the test network with no real money at risk.
