Overview

AI-generated overview

A remote MCP endpoint that hands work between AIs, keeps session memory, and returns a verifiable receipt for every call.

What you can do
  • Search a tool catalog and route natural-language requests to specialist tools
  • Hand over a session to another AI or client, then accept, list and check handovers
  • Save and recall private facts, and manage named continuity threads and preferences
  • Run audits and checks: GitHub code audit, website audit, scam and prompt-injection checks
  • Look up live crypto prices, extract text from public URLs and PDFs, find startup credits and local leads
  • Manage sessions, spending caps, Day Pass activation and status, and close or seal a workflow
When to use it
Useful when you want to move a long task from one AI client to another without losing context, or when you need a checkable record of what an assistant did. Also handy as a single endpoint for assorted one-off jobs such as price lookups, document extraction, site or repo audits and scam checks.
Requirements
Remote Streamable HTTP endpoint; no API key or signup. A session ID is created with new_session and reused across calls and clients. The free tier allows 20 calls plus one wrap-up per day; more usage needs a paid Day Pass or Pass, paid by card, PayPal or USDC on Base.
Before you install
Paid tiers and per-call spending caps are involved; checkout links and activation can lead to real charges, so set a spend limit first. Memory tools store private facts tied to a session, and handovers expose saved state and continuation threads to whoever holds the link or code. Receipts prove saved bytes are unchanged, not that an answer is correct. Some tools send supplied text, URLs or wallet addresses to third-party threat-intelligence and price providers.

Installation

In SourceWeft

  1. Open Zambo in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.zambo%2Fzambo/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

[zambo receipts] [package downloads]

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 Zambo · Verify a receipt · Day Pass · Founder

Free tier: 20 calls + 1 wrap-up free every day; picking up in another AI is always free. Day Pass: $0.99 for unlimited use for 24 hours.

Live proof: check a real receipt from November 7, 2026. Public receipts: 117,789 total, 3,449 issued on November 7, 2026. Live counts: https://zambo.dev/numbers/

Works in Claude, ChatGPT, Grok, Cursor, and any Streamable HTTP MCP client. No API key. No signup.

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.

workflow_close

Workflow Close

Create or return a fixed snapshot with a verifiable receipt of every persisted receipt from this job, including rejected and errored calls. Repeating the call with unchanged receipt data returns the same snapshot workflow_id; later calls after new receipts create a separate snapshot while session_workflow_id continues identifying the live ledger. Both identifiers are unbound metadata excluded from canonical receipt bytes. The first close returns a one-time private workflow_manage_token; retries do not rotate or reissue it. The workflow_close summary receipt is excluded from its own step count. Records Zambo's claims, not issuer authentication. AER-1 receipt, verifiable offline. Required arguments: _session_id.
