// how it works

Up and Running In Seconds

Perimeter gives every agent a safe way to pay: funded up front, governed by policy, approved on your terms, and closed out cleanly.

Step 01

Fund

Add money to your Perimeter Vault

Transfer funds into your Vault to get started. Think of it as a shared pool your agents draw from — you top it up, you decide how it's spent.

Pre-funded · You control the budget
Step 02

Policy

Set the rules before your agent spends

Choose exactly how much each agent can spend, where, and how often. Lock them to specific merchants or categories so they stay on task — and nothing else.

Spend caps · Merchant & category controls
Step 03

Issue

A fresh card, created on demand

When your agent needs to pay, Perimeter issues a new virtual card — instantly. Get notified the moment it's created, with optional approval so you stay in control.

Instant issuance · Optional approvals
Step 04

Revoke

Cards that self-destruct after use

Every card expires the moment the job is done. It can never be reused, stolen, or charged again. Any leftover funds return to your Vault automatically.

Auto-expiry · Instant refunds
// works with your stack

Your agent already knows
how to use it.

Whether you're calling a raw API, running an MCP server, or using OpenClaw — Perimeter fits the workflow your agent already has.

API

Simple API. No lock-in.

Any language. Any framework. Any agent. If your stack can make an HTTP request, it works with Perimeter.

MCP

Native MCP server.

One config block and you're connected. Claude, Cursor, or any MCP-compatible environment gets direct access to Perimeter’s card creation and spend controls.

RECOMMENDED🦞 OPENCLAW

Add the Claw-Card skill.

Install the Claw-Card skill from ClawHub and your OpenClaw agent instantly gains the ability to create cards, and complete purchases.

The only skill on ClawHub that lets your agent spend real money.
Don't see your framework? The REST API works with everything.
