Zambo MCP Server

Zambo

The verifiable work layer for AI.

Give your AI hands, memory, and proof. Your AI forgets everything the second you close the chat. Zambo fixes that: wrap up a session in one AI and continue it in any other with a code, and picking up is always free. One remote MCP endpoint with 153 tools, continuity that carries work across AIs, and a verifiable receipt for every job, so "done" is something you can check.

HANDOVER is the flagship: hand a live job from one AI to another as one link, with the full record attached.

Your first prompt

Paste this into any AI that has Zambo connected:

Get the live BTC price with Zambo, then give me the receipt link so I can check the work.

Open the link it gives you. The receipt shows the exact saved result and its sha-256 digest, so you can check the work instead of trusting the answer. You can also paste any receipt link at zambo.dev/verify.

First move: HANDOVER

HANDOVER is the front door: hand work from one AI to another, or to a client, as one link with the full record attached. The receiving side picks it up and keeps going, and every step carries its receipt.

What you get

• Continuity: memory and sessions that persist across calls, clients, and models. Wrap up a session in one AI and continue it in any other with a code; picking up is always free.
• Tools: 153 behind one endpoint. Research, data, documents, media, payments, and more.
• Proof: every call returns a verifiable AER-1 receipt. A receipt proves the saved result was not changed after it was saved.

Pricing

Free tier: 20 calls + 1 wrap-up free every day; picking up in another AI is always free. Day Pass: $0.99, unlimited for 24 hours. Zambo Pass: $29 for 30 days, $290 for 365 days. $ZAMBO holders: $19 for 30 days. Agents pay with USDC on Base through x402. Humans pay by card or PayPal.

Proof

Zambo receipts follow AER-1, the Agent Execution Receipt standard, now at draft 26: https://datatracker.ietf.org/doc/draft-zambo-aer1/26/ The AER-1 conformance corpus is published (143 vectors, 146 checks, kit v1.5.7), and independent implementations pass it.

Independent baseline

Dominion Observatory, an independent watcher of MCP tool manifests, captured the default 35-tool surface of https://zambo.dev/mcp on 2026-10-30 and published the record in issue #5. Manifest SHA-256: 4520aa4d5cbb8f26913c3e358ed258bf4db24678f28be4aab8875d758e426ca7. The full 153-tool catalog is a separate surface (add ?full=true to the endpoint) and is not part of that baseline. Anyone can fetch the live manifest and compare it against the outside record.

next step: add zambo to your ai in one url, no key, no account: https://zambo.dev/add/?ref=zambo-mcp got a receipt link from someone? check it in seconds: https://zambo.dev/verify/ every call returns a receipt. a receipt proves the saved bytes are unchanged. it does not prove the answer is right.
