🔧 Your MCP Server
🛡 MCP Keeper Proxy
🤖 AI Agent pays via x402
How It Works

Three steps to revenue

Register your server, set prices, and let agents pay per call. Daily payouts to your Stripe account ($1 minimum).

1

Register your MCP server

Point MCP Keeper at your existing server URL. We create a proxy endpoint that agents connect to instead.

2

Set prices per tool

Choose a per-call price for each tool — from $0.001 microtransactions to $1+ for premium operations. Free tools stay free.

3

Agents pay, you earn

When an agent calls a paid tool, MCP Keeper collects payment via the x402 protocol and forwards the request to your server. Payouts land in your Stripe account.

Why MCP Keeper

Built for the MCP ecosystem

Whether you build tools or consume them, MCP Keeper makes paid tools seamless.

🔌

Drop-in proxy

Your server stays unchanged. We proxy MCP JSON-RPC traffic and inject payment gating transparently.

💰

x402 payments

The open HTTP 402 protocol lets agents pay per request using stablecoins — no credit cards, no subscriptions.

📊

Dashboard & analytics

Track calls, revenue, and tool usage from a single dashboard. Manage servers, pricing, and payouts.

🏪

Bazaar discovery

Your tools are automatically listed in the Bazaar marketplace, so agents can discover and connect instantly.

🛡️

Rate limiting

Built-in per-server rate limits protect your infrastructure from abuse and runaway agents.

💸

Stripe payouts

Connect your Stripe account and receive daily payouts ($1 min, 2-day rolling window). We handle platform fees and tax reporting.
