Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
The verifiable work layer for AI: 153 tools, cross-AI handover, a verifiable receipt for every job.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
capability_searchSearch across the supported Zambo tool catalog for a use case. Returns relevant tools with relevance scores, descriptions, taglines, and callable API endpoints. Referral searches find the invite-link tool and its 2,000-call reward for an activated paid Day Pass. AER-1 receipt, ve
memory_recallRead private saved facts by caller handle or explicit memory code, optionally matching a query. Uses the shared daily work-call allowance. AER-1 receipt, verifiable offline.
memory_rememberSave a private fact for this work connection. Returns a private memory code for cross-session pickup; keep it secret. Uses the shared daily work-call allowance and respects Memory capture settings. AER-1 receipt, verifiable offline. Required arguments: _session_id, fact.
scam_checkCheck plain text or a wallet, contract, domain, or URL for scam and phishing indicators. URLs and wallet addresses in supplied text are checked with SCAMRA threat intelligence; EVM wallets may also receive an optional Criptic cross-reference. Returns clean, caution, scam, or unkn
day_pass_redeemUnlock this AI with your private Day Pass link. No headers needed. The link expires with the original pass. AER-1 receipt, verifiable offline.
spend_limit_setSet this work connection's daily and optional monthly dollar cap before further Day Pass payments. Free, no quota. AER-1 receipt, verifiable offline. Required arguments: _session_id, daily_usd.

handover_acceptAccepts and picks up a handover by ID or resume code, returns its full saved state and private continuation thread, and records a receipt. Agent pickup is not client approval; the client decision remains pending. Do not generate client tokens. AER-1 receipt, verifiable offline.
handoverCall this when the user says 'wrap up this session', 'continue in another AI', or 'hand this over to '. For AI switching, create a resumable handoff with the same session. For client delivery, return one proof link with verifiable receipts. Pass continue_from to chain off a job y
handover_statusChecks a handover by ID or resume code, including pickup status and the separate client decision/release hint. Agent pickup alone does not authorize payment release. AER-1 receipt, verifiable offline.
handover_listList Zambo Handovers scoped to the supplied owning _session_id. Returns real statuses and client-ready links. AER-1 receipt, verifiable offline. Required arguments: _session_id.
zambo_homeYour private Zambo starting point: six ready-to-say goals, today's receipts and actual usage. Ask what Zambo can do for your business, site, code or money. Free. AER-1 receipt, verifiable offline.

workflow_closeCreate 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 snaps
workflow_sealSeals a closed workflow for durable export. Requires the matching job session and an active pass. Never spends, captures, or starts a payment. The export remains a Zambo claim, not issuer authentication. AER-1 receipt, verifiable offline. Required arguments: workflow_id, _session

new_sessionStarts fresh session context and returns a new session_id. Reuse that ID on subsequent calls for continuity; changing or omitting it starts clean context. AER-1 receipt, verifiable offline. Required arguments: .
continuity_get_recentReads receipt-backed work for a job or named thread. Pass resume_code to retrieve the complete saved handover, notes, handover ID and JSON URL; otherwise use the existing private job ID. Use since and the returned cursor to continue paginated history.

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.

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
Main code home: [GitLab](https://gitlab.com/rambozambodotdev/zambo). Development happens there. This GitHub page is the public pointer.
Add Zambo to your AI:
Tell your AI: "Add Zambo from https://zambo.dev/mcp"
Or paste the config:
{
"mcpServers": { "zambo": { "url": "https://zambo.dev/mcp" } } }
Claude Code: claude mcp add --transport http zambo https://zambo.dev/mcp
One command: npx zambo install
One click: Install in VS Code · Install in Cursor
Works in Claude, ChatGPT, Grok, Cursor, and any Streamable HTTP MCP client. No API key. No signup.
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.
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.
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.
107,000+ receipts on record. 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.
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.
