**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.

## Add it
Tell your AI: "Add Zambo from https://zambo.dev/mcp"
Or paste the config:
```json
{
"mcpServers": {
"zambo": {
"url": "https://zambo.dev/mcp"
}
}
}
```
**Claude Code:** `claude mcp add --transport http zambo https://zambo.dev/mcp`
**One command:** `npx zambo install`

## 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](https://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: every tool free once a day, plus 3 continue calls. One free wrap-up handover per day, and pickup is always free..
Day Pass: $0.99, unlimited for 24 hours.
Zambo Pass: $29 for 30 days. $ZAMBO holders: $19 for 30 days. Lifetime Pass: $250, one payment.
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](https://github.com/zambodotdev/zambo-mcp/issues/5#issuecomment-6511599676). 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.
