\n\n---\n\n## Quick Start\n\n```bash\nnpm install @settlegrid/mcp\n```\n\n```typescript\nimport { settlegrid } from '@settlegrid/mcp'\n\nconst sg = settlegrid.init({\n toolSlug: 'my-tool',\n pricing: { defaultCostCents: 5 },\n})\n\nconst billedHandler = sg.wrap(myHandler)\n```\n\nEvery call validates the consumer's API key, checks their credit balance, executes your function, and meters usage — all with a single Redis balance check on the hot path.\n\nOr scaffold a complete project instantly:\n\n```bash\nnpx create-settlegrid-tool\n```\n\n

Every active tool is automatically discoverable across:\n\n| Channel | How it works |\n|---------|-------------|\n| **[Showcase](https://settlegrid.ai/tools)** | Consumers browse, search, and purchase credits |\n| **[Discovery API](https://settlegrid.ai/docs#discovery)** | `GET /api/v1/discover` — programmatic search for directories & apps |\n| **[MCP Discovery Server](https://www.npmjs.com/package/@settlegrid/discovery)** | AI agents find tools natively via MCP protocol |\n| **[HTTP MCP Endpoint](https://settlegrid.ai/api/mcp)** | Remote streamable HTTP transport for any MCP client |\n| **[Official MCP Registry](https://registry.modelcontextprotocol.io)** | The canonical MCP server registry |\n| **[Smithery](https://smithery.ai)** | 6,000+ MCP server directory |\n| **[Glama](https://glama.ai)** | 14,000+ MCP server directory |\n| **[RSS Feed](https://settlegrid.ai/api/feed)** | New tools syndicated automatically |\n\n

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.\n\n**9 brokered by the Smart Proxy** (production or pending GA):\nMCP · x402 (Coinbase) · Stripe MPP · AP2 (Google) · ACP (OpenAI) · UCP (Google/Shopify) · Visa TAP · Mastercard Verifiable Intent · Circle Nanopayments\n\n**2 detection-adapter-only**:\nL402 (Bitcoin Lightning) · KYAPay (Skyfire)\n\n**3 tracked as emerging**:\nACTP (Alipay's Agentic Commerce Trust Protocol) · EMVCo agent payments · DRAIN (Bittensor Subnet 58)\n\n## Features\n\n**Billing & Metering**\n- A single Redis balance check on the hot path, on every call\n- Budget enforcement — HTTP 402 when exceeded\n- Auto-refill credits via Stripe\n- Multi-hop settlement across agent chains — each hop settled as it completes\n\n**Security & Compliance**\n- Agent identity (KYA) with trust scoring\n- Fraud detection (12 real-time signals)\n- IP allowlisting (CIDR support)\n- HMAC-SHA256 webhook signatures\n- Audit logging with CSV export (SOC 2 ready)\n- Sandbox/test mode\n\n**Developer Experience**\n- `sg.wrap()` — one function, any handler\n- 6 pricing models configurable from dashboard\n- 97 open-source templates with billing pre-wired\n- CLI scaffolder: `npx create-settlegrid-tool`\n- Discovery tab with badge generator, checklist, API URLs\n- Consumer reviews with developer responses\n- Quality gates + Verified badge for activated tools\n- Proactive monitoring (onboarding drip, quality alerts, monthly summary)\n\n## Pricing\n\n| Tier | Price | Ops/month | Take Rate |\n|:---:|:---:|:---:|:---:|\n| **Free** | $0 forever | 25,000 | 0% |\n| **Starter** | $9/mo | 100,000 | 5% |\n| **Growth** | $29/mo | 500,000 | 5% |\n| **Scale** | $79/mo | 2,000,000 | 5% |\n\n$1 minimum payout — the lowest in the industry. Stripe Connect Express for instant payouts.\n\n## REST API Middleware\n\nFor non-MCP services (Express, Next.js, Hono, etc.):\n\n```typescript\nimport { settlegridMiddleware } from '@settlegrid/mcp'\n\nconst withBilling = settlegridMiddleware({\n toolSlug: 'my-api',\n costCents: 5,\n})\n\nexport async function GET(request: Request) {\n return withBilling(request, async () => {\n return Response.json({ data: 'hello' })\n })\n}\n```\n\n## Project Structure\n\n```\nsettlegrid/\n├── apps/web/ # Next.js 15 platform (settlegrid.ai)\n├── packages/mcp/ # @settlegrid/mcp SDK\n├── packages/discovery-server/ # @settlegrid/discovery MCP server\n├── packages/create-tool/ # npx create-settlegrid-tool CLI\n├── open-source-servers/ # 1,017 indexed MCP servers\n└── .mcp.json # MCP plugin config (Cursor, Claude)\n```\n\n## Links\n\n| | |\n|---|---|\n| **Website** | [settlegrid.ai](https://settlegrid.ai) |\n| **Documentation** | [settlegrid.ai/docs](https://settlegrid.ai/docs) |\n| **Discovery Guide** | [settlegrid.ai/learn/discovery](https://settlegrid.ai/learn/discovery) |\n| **Handbook** | [settlegrid.ai/learn/handbook](https://settlegrid.ai/learn/handbook) |\n| **API Reference** | [settlegrid.ai/api/openapi.json](https://settlegrid.ai/api/openapi.json) |\n| **Discovery API** | [settlegrid.ai/api/v1/discover](https://settlegrid.ai/api/v1/discover) |\n| **RSS Feed** | [settlegrid.ai/api/feed](https://settlegrid.ai/api/feed) |\n| **npm (SDK)** | [@settlegrid/mcp](https://www.npmjs.com/package/@settlegrid/mcp) |\n| **npm (Discovery)** | [@settlegrid/discovery](https://www.npmjs.com/package/@settlegrid/discovery) |\n| **MCP Registry** | [io.github.lexwhiting/settlegrid-discovery](https://registry.modelcontextprotocol.io) |\n| **Support** | support@settlegrid.ai |\n\n## License\n\nMIT © 2026 [SettleGrid](https://settlegrid.ai)\n", "bytes": 9257, "sha": "9f0f9173a6b32e22be6aa4e7e89d26ec1f1d4aa1d29d63b41afe3eb1484142f9", "repo_slug": "lexwhiting/settlegrid", "fonte": "repo", "truncated": false, "api": "https://agentalog.com/api/listings/mcp_io_github_lexwhiting_settlegrid_discover_d6a3c164/readme" }
