Can't be undone 2Claude Code: ask
send_messageSend a message to the other party of an order (task details, files to process, questions).No findings
Why it is in this group
- The name "send_message" says "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it Send a message to the other party of an order (task details, files to process, questions). Requires login as the buyer or seller. Do not include secrets: the seller and the arbitrator can read it.
send_proposalSend a proposal for an open request: your price, delivery time and how you will do the work (optionally split into 2 to 10 milestones).No findings
Why it is in this group
- The name "send_proposal" says "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it 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.
Changes things 7Claude Code: ask
accept_proposalAccept one proposal for your request.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote 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).
create_orderPrepare (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.No findings
Why it is in this group
- The name "create_order" says "create": a word for a change.
Description, as the server wrote it 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.
loginStep 2 of signing in: send the message from prepare_login and its signature.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Step 2 of signing in: send the message from prepare_login and its signature. Returns a sessionToken (valid up to 7 days) to pass to the tools that need a signed-in wallet. Treat it as a secret.
post_requestPost a task that is not in the catalog so people can send proposals (price, delivery time, approach).No findings
Why it is in this group
- The name "post_request" says "post": a word for a change.
Description, as the server wrote it Post a task that is not in the catalog so people can send proposals (price, delivery time, approach). Use it when search_services finds nothing that fits; its result includes a draft. Requires login. The request is public: do not include secrets or private data; send those later with send_message to the chosen seller.
prepare_loginStep 1 of signing in to Mercadopleis (needed to register orders, message the seller and download deliverables).No findings
Why it is in this group

Why it is in this group
- The description's first verb is "link": a word for a change.
