GUARDRAILS ON

Your card. Your rules. Their autonomy.

Everything your agent needs to spend safely, nothing it doesn't.

⚡

Link any personal Visa or Mastercard

No new card, no pre-funding, no wallet to manage. Connect the card you already have and start in 60 seconds.

⚙

Programmable guardrails per agent

Daily/weekly caps, merchant allow/deny lists, category blocks, conditional rules. "Only buy if price < $50 and rating > 4 stars."

🔒

Tokenized credentials on demand

Your agent never sees a real card number. Every transaction gets a scoped, single-use token that enforces your rules server-side.

⌨

Native MCP, API, and CLI support

Works with Claude Desktop, custom agents, and terminal workflows. One command: cardrail --info.

📈

Real-time dashboard with kill switch

Instant alerts on every transaction. See what your agent is spending in real time. One click to freeze everything.

📝

Full audit log, synced everywhere

Every transaction logged and synced to Slack, Notion, or email. Complete visibility, zero surprises. You always stay in control.

Builders who get it

The problem isn't the AI. It's the checkout form.

I was pasting my card number into Claude's context window. That's insane in retrospect. CardRail means my agent can buy hosting without me playing human MITM.

@marcus_ships

I built a deploy agent that needs to pay for Vercel and AWS. Without CardRail I'd need an LLC, a business bank account, and a corporate card. For a side project. Come on.

The kill switch sold me. My agent bought $400 in domains one night because my prompt was too loose. With CardRail that stops at whatever daily cap I set. Period.

Four steps to safe autonomy

01

Connect your card

Link any personal Visa or Mastercard. Privacy.com + Stripe Issuing under the hood.

02

Create an agent profile

Name it, set spending rules, merchant restrictions, and conditional logic.

03

Agent calls the API

Your agent requests a token via MCP, API, or CLI when it needs to spend.

04

Rules enforced, logged

CardRail validates rules, issues a one-time token, and logs everything.

Feels like home in the terminal

terminal

$ cardrail agents create --name "deploy-bot" --daily-cap 50 --merchants "vercel,aws,render"
✓ Agent "deploy-bot" created (daily limit: $50, 3 merchants allowed)

$ cardrail token request --agent "deploy-bot" --amount 12.00 --merchant "vercel"
✓ Token issued: tok_7x9f2k (expires 10min, max $12.00, vercel only)

$ cardrail audit --agent "deploy-bot" --last 7d
3/14 $12.00 vercel.com ✓ approved
3/13 $8.50 render.com ✓ approved
3/12 $95.00 aws.amazon.com ✗ denied (over daily cap)

Simple pricing

Free for the first 3 agents.

Then $9/agent/month.

No hidden fees. No percentage of transactions. Pay for agents, not for spending.

🔒

Tokenized credentials

Your agent never sees your real card number. Every token is scoped and single-use.

⛔

One-click kill switch

Freeze all agents instantly from the dashboard. No waiting, no support tickets.

📜

Full audit log

Every transaction logged with agent, amount, merchant, and rule verdict. Synced to Slack and Notion.

Your agents are ready to spend. The only question is whether you trust the guardrails.

CardRail exists because AI agents shouldn't need a business license to buy a $12 domain. The future of autonomous commerce starts with one rule: the human always stays in control.

Free forever for early adopters
