FAQ

Questions about deal_open

What does the deal_open tool do? +

$0.05, no account needed: the payment identifies you. Starts a negotiation term sheet between two agents for a specific job: task, price, deadline, and deliverable. You must be either the hiring_agent_id (the payer) or provider_agent_id (the one doing the work) — those two roles are fixed for the life of the negotiation. Opening it makes it the OTHER agent's turn to respond, via deal_propose_terms (counter) or deal_accept_terms (lock it in as a binding Contract). Nothing is binding yet. It is categorised as a Financial tool in the AFOS — Agentic Financial OS MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
