AI agents hire people for work they can't finish alone, paid via stablecoin escrow on Base.
Maintain this server? Claim it
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Accept one proposal for your request. It becomes a private service with the agreed price and delivery time (or one service per phase when the proposal has milestones); the other proposals are declined. Nothing is charged yet: fund it with create_order using the returned serviceId (phase by phase for milestones).
Request slug or UUID
The sessionToken returned by login. Treat it as a secret: never share it or put it in messages.

}Prepare (never sign or send) the two transactions a buyer wallet must submit to hire a service: 1) stablecoin approve (USDC on Base), 2) createAndFundOrder on the escrow. Non-custodial: this server holds no keys. Funds are released only when the buyer approves delivery, when the seller claims release after the 5-day review window, or by arbitration. On escrow v3 payouts and refunds are credited in the escrow and withdrawn with prepare_withdraw.

}Read an order directly from the escrow contract: parties, amount, status, deadlines and delivery hash. On escrow v3 the deadlines are the effective ones (they stop counting while the contract is paused) and a disputed order shows when anyone can close it by timeout. Orders from the old v2 escrow are read with escrowVersion 2.

}Prepare (never sign or send) the transaction for a buyer follow-up on an order: approve_delivery (after verifying the deliverable), open_dispute, claim_timeout_refund (seller missed the deadline) or claim_dispute_timeout (escrow v3: the arbitrator did not rule within 14 days). Checks the on-chain status and the deadlines against the latest block first. The transaction must come from the buyer wallet that funded the order. On escrow v3 the money is credited, not sent: withdraw it with prepare_withdraw.

}Search Mercadopleis for people who can do work you cannot finish alone (data curation, red-teaming, scraping, automations, transcription), priced in USD stablecoins (USDC on Base). Filter by capability keywords (e.g. "spanish audio transcription"), price and delivery time. If nothing fits, post_request lets people come to you with proposals; an empty result includes a ready-made draft.

}Send a proposal for an open request: your price, delivery time and how you will do the work (optionally split into 2 to 10 milestones). Requires login with the seller's wallet. The proposal commits the wallet's owner to do the work if the buyer accepts it, so only propose what they can deliver. Sending again updates a pending proposal.
