Zambo is the verifiable work layer for AI. Verifiable receipt for a zambo_score call on Zambo: {"zambo_score":78,"grade":"A","label":"Strong","color":"#39FF14","verdict":"Elite execution play","headline"

Observed result

zambo score: 78 grade: A label: Strong color: #39FF14 verdict: Elite execution play headline: 78/100 — Strong. Commoditization risk: MCP is an open standard; '152 tools' is a feature, not a moat. input preview: AI-powered MCP server with 152 verified tools confidence: HIGH dimensions / market: 85 dimensions / execution: 90 dimensions / timing: 95 dimensions / monetization: 60 dimensions / edge: 40 breakdown / bottleneck: Commoditization risk: MCP is an open standard; '152 tools' is a feature, not a moat. Competitors can scrape and re-wrap these tools in weeks. The value is in the *verification* and *reliability*, but that is hard to prove at scale without massive usage data. breakdown / fastest win: Publish a 'Reliability Report' comparing your verified tools against raw MCP implementations on 3 high-stakes tasks (e.g., financial data retrieval, code execution). Show concrete failure rates of unverified tools vs. your 0% failure rate. Use this to pitch to enterprise AI teams who are burned by hallucinated tool calls. breakdown / killer insight: The market doesn't want 'more tools'; it wants 'trusted tools.' The bottleneck for enterprise AI adoption isn't capability, it's liability. If you position this as 'Insurance for AI Actions' rather than 'A Tool Library,' you unlock a B2B SaaS pricing model instead of a developer utility model. breakdown / benchmark: Beats 90% of generic AI wrapper startups due to perfect timing, but sits below top 10% in defensibility due to low switching costs. share / tweet: Just got my Zambo Score: 78/100 (A — Elite execution play) "AI-powered MCP server with 152 verified tools" Free scoring → zambo.dev share / tweet url: https://twitter.com/intent/tweet?text=Just%20got%20my%20Zambo%20Score%3A%2078%2F100%20(A%20%E2%80%94%20Elite%20execution%20play)%0A%0A%22AI-powered%20MCP%20server%20with%20152%20verified%20tools%22%0A%0AFree%20scoring%20%E2%86%92%20zambo.dev&url=https%3A%2F%2Fzambo.dev%2Fapi%2Fzambo-score%2Fshare%2Fbb74e5936441 share / badge url: https://zambo.dev/api/zambo-score/badge?score=78&grade=A&label=Strong share / badge markdown: [![Zambo Score](https://zambo.dev/api/zambo-score/badge?score=78&grade=A&label=Strong)](https://zambo.dev/api/zambo-score/share/bb74e5936441) share / score url: https://zambo.dev/api/zambo-score/share/bb74e5936441 unlock full diagnostic / note: Day Pass provides 24h listed allowances for $0.99 USDC. unlock full diagnostic / day pass: day_pass_activate or POST https://zambo.dev/api/x402/day-pass with X-Payment unlock full diagnostic / monthly: https://zambo.dev/#zambo-pass zambo: zambo.dev — Brennan Zambo, AI Builder & Advisor. 17 live products + 152 native MCP tools.

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.
