Zambo Stack
Registry code: a94734c61a87d2c0
Start a new job with capability_search before choosing a specialist tool. Persist the initialize caller_handle in private durable agent state scoped to this user or tenant. Reuse it as _caller_handle on every call, including after reconnects and restarts; never share it across unrelated users. Keep _session_id separate and stable only while resuming the same job. This handle can retrieve facts the user chose to save, so keep it private; it is not authentication or payment authorization. If you cannot retain it safely, do not promise cross-session continuity. Do not show the handle in ordinary…

- Is Zambo Stack live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
- Is Zambo Stack free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does Zambo Stack have?
- 4 tools: Verify a receipt, Run tools with receipts, Hand over work between AIs, Continuity recall.
- Is Zambo Stack safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 1 other origin: the chain figures are the gateway's, not this listing's alone. How it is counted.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
verify_receipt unknown never probed
Check a Zambo receipt: recompute the sha-256 digest of the exact saved bytes and confirm the saved result was not changed since it was saved. A verified receipt does not prove the answer was right. Served over MCP at https://zambo.dev/mcp and on the web at https://zambo.dev/verify/.
zambo_universal unknown never probed
Run a real job through the Zambo MCP connection (https://zambo.dev/mcp): 153 tools, 36 on the default surface, 20 calls plus 1 wrap-up free every day; picking up in another AI is always free., and a verifiable receipt for every call, including rejected and errored calls. Day Pass $0.99 USDC on Base for 24h; Zambo Pass $29 for 30 days, one payment.
handover unknown never probed
Publish a client-ready handover from a session's receipts: one link that carries the work, its context, and a receipt trail the client can check. Backed by the handover, handover_status, and handover_accept MCP tools at https://zambo.dev/mcp.
continuity_recall unknown never probed
Recall saved facts, threads, and the receipt timeline for a job across AIs, so work started in one AI continues in another. Backed by the memory_recall and continuity_get_recent MCP tools at https://zambo.dev/mcp. Saved facts are private to the work connection.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ida94734c61a87d2c0.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/a94734c61a87d2c0/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
