Quick Start

npm install @settlegrid/mcp

import { settlegrid } from '@settlegrid/mcp'

const sg = settlegrid.init({
  toolSlug: 'my-tool',
  pricing: { defaultCostCents: 5 },
})

const billedHandler = sg.wrap(myHandler)

Every call validates the consumer's API key, checks their credit balance, executes your function, and meters usage — all in under 50ms.

Or scaffold a complete project instantly:

npx create-settlegrid-tool

Why SettleGrid?

Discovery — Your Tools, Found Everywhere

SettleGrid doesn't just bill — it distributes. Every active tool is automatically discoverable across:

<p align="center"> <img src="https://settlegrid.ai/screenshots/Showcase.jpg" alt="SettleGrid Showcase" width="800" /> </p>

{
  "mcpServers": {
    "settlegrid-discovery": {
      "command": "npx",
      "args": ["@settlegrid/discovery"]
    }
  }
}

6 Pricing Models

Payment Protocol Coverage

The @settlegrid/mcp SDK adds native billing to any Model Context Protocol (MCP) tool server and provides a REST middleware for any HTTP service. On top of that, the hosted Smart Proxy at settlegrid.ai/api/proxy/{slug} brokers payments across agent payment protocols and tracks emerging specs as they mature.

9 brokered by the Smart Proxy (production or pending GA): MCP &middot; x402 (Coinbase) &middot; Stripe MPP &middot; AP2 (Google) &middot; ACP (OpenAI) &middot; UCP (Google/Shopify) &middot; Visa TAP &middot; Mastercard Verifiable Intent &middot; Circle Nanopayments

2 detection-adapter-only: L402 (Bitcoin Lightning) &middot; KYAPay (Skyfire)

3 tracked as emerging: ACTP (Alipay's Agentic Commerce Trust Protocol) &middot; EMVCo agent payments &middot; DRAIN (Bittensor Subnet 58)
