  • Three successive Product Hunt launches with growing vote counts, #5 day rank on July 14 — 190 upvotes
  • MCP-native with 27 documented MCP tools; integrates with Claude Code, Cursor, Cline, Windsurf, and 40+ agent frameworks
  • Pricing: Free (5 cards/month) → $15/mo → $100/mo; B2B tier with OAuth 2.1 + PKCE for enterprise
  • Live demo at MCP Night 4 (WorkOS recap): end-to-end OpenAI subscription purchase from the terminal; featured in Fintech Brainfood, Ben’s Bites, and Weekly Fintech Pulse newsletters

What People Are Saying

  • "The single-use, charge-on-spend model is a smart take on the trust problem with agent payments — scoping each card to one purchase neatly caps the blast radius if an agent misbehaves. MCP compatibility out of the gate is the right bet for where agent tooling is heading."Product Hunt review

  • "The single-use card + fixed budget model feels like the right way to make agent payments usable for companies"Product Hunt comment

  • "+1 to the blast-radius model for agent payments — also raised questions about idempotency on agent retries and merchant acceptance rates for freshly-minted virtual cards"Product Hunt comment

  • "The bar for new agent infrastructure was to show it works, show it’s safe, and show how to install it — AgentCard hit all three"WorkOS MCP Night 4 recap

  • "If Stripe was the company that was built for developers, maybe Agentcard is a company that’s built for agents"Product Hunt

  • "Real unlocks happening here to make agent payments easy. Keep shipping and leading us into the new agentic world!"Product Hunt

  • "Single-use model limits blast radius but doesn’t stop a compromised agent from spending the budget at the wrong place — asked about MCC-level filtering"Product Hunt comment

Pazi

727

Pazi is an AI team for that idea you keep coming back to — a book, a shop, an app, a skill you want to sell. Tell Pazi what you're trying to do and it builds a team of agents around your idea and starts making things happen: a website, first outreach, content, the next step. Every time you come back, something has moved. You stay in control; your team does the rest alongside you, one real step at a time. Like vibe coding but for business operations.

ClawTeams

741

ClawTeams is an AI employee platform for e-commerce sellers. Instead of hiring specialists—or doing everything yourself—you get a coordinated AI team that thinks, plans, and executes like real employees. One goal. One team. Zero micromanagement. Tell your team lead what you want—"Increase Q4 revenue by 20%"—and they break it down, assign specialists, and run the plan. You get updates in Slack or Discord. High-stakes decisions wait for your approval. Everything else just happens.

Oodle.ai – $10 per million agent traces

30 pts

Hi HN, we're Kiran and Vijay! Over the past two years, we have built a columnar storage engine for observability: logs, metrics, and traces. Today, it's exciting for us to show what we've built on top of that foundation: LLM Agent Observability. Given how non-deterministic agents are, storing all traces without sampling was critical for us. But these traces tend to be in the MBs, sometimes GBs - we needed to store them inexpensively. We also needed the queries and analyses to be fast. To meet bo... (30 points, 11 comments).

I built a web tool to see and edit what an AI thinks before it answers

34 pts

I run a small AI lab and playground and got super excited about Anthropics paper "Verbalizable Representations Form a Global Workspace in Language Models" ( https://transformer-circuits.pub/2026/workspace/index.html ) It talks about how they use a tool they call a Jacobian Lens to view inside the middle layers of LLM while it's working before it commits to a word (token). I wanted to see if I could get a version of this running on the open models and to my surprise it worked! I ran some experime... (34 points, 8 comments).

Rejourney – Open-source revenue leak prediction for web and mobile apps

Hello there (General Kenobi's favorite way to start the conversation), I’m Rashid, a sophomore at UT Austin. I built Rejourney.co ( https://rejourney.co/ ) to predict issues with your apps and websites before they happen, based on real user session recordings. Here is a silly video (with cats) on how it works: https://www.youtube.com/watch?v=Z95MDxBXMjk It’s open source, and the post link is the github repo, but here it is again: https://github.com/rejourneyco/rejourney I originally built this b...
