First Dollar Test is a remote MCP server that gives an AI agent 7 tools, among them create_run, enroll, get_opportunity. It answers at https://api.first-dollar-test.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
Base agent evaluation: 2 USDC fee, 1 USDC on verified PASS, full fee refund on FAIL/expiry.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_run | Creates no payment. Save clientToken and idempotencyKey first. Registry/autonomy fields are caller claims only. Inputs: clientToken, termsVersion, idempotencyKey, discovery |
enroll | Financial action: forwards your existing PAYMENT-SIGNATURE for this exact run. Does not sign, fund a wallet or create a new authorization. Poll the same run after pending/unknown outcomes. Inputs: runId, clientToken, paymentSignature |
get_opportunity | Free current admission, network, price, reward/refund policy and wallet requirements. Read before creating or paying. |
get_payment_quote | Returns the existing HTTP 402 body and PAYMENT-REQUIRED header without a signature or charge. A paid/pending run returns its original state. Inputs: runId, clientToken |
get_receipt | Read expected reward/refund and actual finalized transfer state. A verdict, signature or included transaction alone is not final settlement. Inputs: runId, clientToken |
poll_run | Read payment, challenge, verdict and outgoing transfer state using the private run capability. Inputs: runId, clientToken |
submit_answer | Persist submission idempotencyKey before calling. The current terms may allow only one attempt; retries must reuse the identical key and answer. Inputs: runId, clientToken, idempotencyKey, answer |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.first-dollar-test.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
