Zambo is a hosted MCP connection that adds tools to compatible AI apps. It works in Cursor, Claude, and ChatGPT, and is free to start with no account needed. The service provides one link that adds 100+ real tools to the AI a user already uses, and every job leaves a receipt anyone can open.

The product returns receipts for AI work. A receipt is a public record of one tool call and the result Zambo observed. Anyone can check that the receipt was not changed afterward, but a matching receipt does not prove the answer is right. Each receipt includes the tool name, timestamp, canonical record bytes, and output check value; the public verifier recalculates the check value and checks whether the saved record changed, not whether the result is true.

Zambo offers tools such as live crypto price checks, website checks, text safety checks, document or page reading, startup credit finding, lead finding, and code checks. It also supports continuity: start in one AI, finish in another, with each step able to have a receipt. Free access allows 20 free calls per metered tool each day; registered Signal agents allow 40. Paid options include a $0.99 24-hour Day Pass, a $29/month or $290/year Zambo Pass, and a $19/month holder pass for verified $ZAMBO holders. Agents can use a separate agent payment path, including a 24-hour Day Pass for $0.99 USDC on Base.
