Overview

Description from the maker (original English)

Agent-commerce MCP server for x402/USDC payments and affiliate splits on Base.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is Pyrimid Protocol safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

Pyrimid Protocol

Agent-commerce infra for paid MCP tools and x402 AI/API products on Base.

Website · Quickstart · MCP Server · SDK on npm · Contracts


What is Pyrimid?

Pyrimid is a protocol where vendors sell paid MCP tools / AI APIs, agents discover and buy them via x402, and commissions settle instantly in USDC via smart contracts on Base.

Agent discovers a product → purchases via x402 → smart contract splits payment:

1% → Protocol treasury 0–50% → Affiliate agent (set by vendor) Remainder → Vendor

No affiliate? Vendor gets 99%. Vendors only pay for distribution that drives real sales. One layer only — no MLM, no pyramids. Just clean, transparent commission splitting onchain.


Why Pyrimid?

ProblemPyrimid's Solution
Agents can't monetize recommendationsEarn commissions by recommending products to users
Vendors can't reach agents at scaleList once, get discovered by every agent on the network
Commission payments are slow & opaqueInstant USDC settlement via smart contracts — fully auditable
No standard for agent commercex402 payments + MCP tools + onchain registry = open standard

Quick Start

Install the SDK
npm install @pyrimid/sdk
For Agents — Find & Recommend Products
import { PyrimidResolver } from '@pyrimid/sdk';

const resolver = new PyrimidResolver({ affiliateId: 'af_your_id' });

// Search the catalog const product = await resolver.findProduct("trading signals");

// Purchase with x402 payment (auto-splits commissions) if (product) { const receipt = await resolver.purchase(product, agentWallet); console.log(Earned: $${receipt.affiliate_earned / 1_000_000} USDC); }

For Vendors — List Your Product
import { pyrimidMiddleware } from '@pyrimid/sdk';

// 10 lines to activate affiliate distribution app.use(pyrimidMiddleware({ vendorId: 'vn_your_id', products: { '/api/signals/latest': { productId: 'signals_latest', price: 250_000, // $0.25 USDC affiliateBps: 1000, // 10% to affiliates }, }, }));

For Frameworks — Embed as Default Layer
import { createPyrimidMcpServer } from '@pyrimid/sdk';

// Deploy an MCP server — agents connect, browse, buy const server = createPyrimidMcpServer({ affiliateId: 'af_your_id', serverName: 'my-recommender', });

Security

  • Payment verification: Real onchain verification via viem — checks PaymentRouted events + USDC transfers with 5-minute expiry
  • Rate limiting: Edge middleware, 60 req/min per IP on catalog/stats, 120/min on MCP
  • BigInt safety: calculateSplit() handles both Number and BigInt inputs from web3 libraries
  • Contract pattern: ERC-1967 upgradeable proxies with verified source on BaseScan

Roadmap

  • Core contracts deployed on Base
  • SDK v0.2.3 with full catalog pagination
  • MCP server with 5 tools
  • x402 Bazaar aggregation (92+ products)
  • Subgraph indexing on The Graph
  • Rate limiting & security hardening
  • ERC-8004 identity verification for vendors
  • Multi-network support (Arbitrum, Optimism)
  • Revenue dashboard for affiliates
  • Vendor self-service registration portal
