Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for x402-money-farm, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Claude Code:
Any other MCP client works the same way — it is a plain stdio server.
Try it before paying anything
Then have the agent call farm_catalog. It reports the live prices, whether a
wallet is configured and how much has been spent this session. Nothing is
billed, and no wallet is needed to see it. If the prices do not suit you, you
learned that for free.
Configuration
The server pays from your wallet, one call at a time. Gas is paid by the facilitator, so the wallet needs USDC on Base but no ETH.
| Variable | Default | Meaning |
|---|---|---|
X402_PRIVATE_KEY | — | Your funded Base wallet, 0x + 64 hex characters. Without it the paid tools decline with an explanation and only farm_catalog works. |
X402_MAX_USD | 1.00 | Hard spend cap for the process. Once reached, every further paid call is refused. |
FARM_BASE_URL | https://x402-money-farm.fly.dev | The service to buy from. |
X402_NETWORK | eip155:8453 | Base mainnet. |
Fund a wallet for this purpose with a few dollars — not your main one. The key sits in a config file on disk; treat it accordingly. The spend cap exists so a looping agent cannot drain even that wallet.
What a call costs, exactly
The price in the table is the whole price. No monthly minimum, no per-seat fee,
no metered surprise. The server returns HTTP 402 with the exact amount, your
wallet signs that amount, and you get the answer after settlement. A failed
call is not billed. Every response carries a _payment block with the amount,
the running session total and the paying address, so you can reconcile against
the chain yourself.
Why pay-per-call at all
Because the alternative is a signup, a credit card, a minimum plan and a key to rotate — for an agent that wanted the metadata of four URLs. Here the agent decides on its own, pays four cents, and nobody had to create an account.
