PopNx MCP’s three pillars

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

Common questions

Is Mazza Group AI APIs safe?

It passed 3 of 3 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 (1.2.0) reached the registry 3 days 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?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

mazzagrp-mcp

23 AI APIs from mazzagrp.com behind one MCP endpoint. Agents pay per call with x402 v2 / USDC on Base mainnet — no API keys, no signup, no subscription.

Use the remote server (recommended)

Nothing to install. Point your client at the URL:

{

"mcpServers": { "mazzagrp": { "type": "http", "url": "https://mazzagrp.com/mcp" } } }

Claude Code: claude mcp add --transport http mazzagrp https://mazzagrp.com/mcp Cursor / Grok / any client that takes a URL: paste https://mazzagrp.com/mcp.

Payments are signed by the client's own wallet (the x402 flow returns a 402 with the requirements; your client settles in USDC on Base). The remote server never holds your key.

Use the stdio package (legacy, local wallet)

pip install mazzagrp-mcp
{

"mcpServers": { "mazzagrp": { "command": "mazzagrp-mcp", "env": { "MAZZAGRP_WALLET_KEY": "0xYOUR_PRIVATE_KEY" } } } }

Or with a wallet file: MAZZAGRP_WALLET_PATH=/path/to/wallet.json ({"private_key": "0x...", "address": "0x..."}).

Nota: il pacchetto stdio espone 21 tool con i nomi storici (recall, rag,

sql, …). Il server remoto — quello a cui punta il registry — ne espone 23 con

nomi più espliciti (knowledge_recall, rag_query, text_to_sql, …).

Le API sottostanti sono le stesse. Per i client nuovi usa il remoto.

Source of truth: /.well-known/x402.json (23 endpoints, generated from the API's own endpoint table).

How payment works

  1. The agent calls a tool.
  2. The API replies HTTP 402 with the x402 v2 requirements (accepts[0].amount, network eip155:8453).
  3. The client signs an EIP-712 authorisation with its own wallet.
  4. It retries with the PAYMENT-SIGNATURE header.
  5. The response comes back — the USDC settlement happens on Base.
  • Network: Base mainnet (eip155:8453)
  • Asset: USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
  • Treasury: 0xD98b6969fab0bA4D4BB086fF273ff7CCD284CEe8

⚠️ Le versioni precedenti di questo README dicevano "Base Sepolia (testnet)".

Era sbagliato: il servizio è su Base mainnet. Un wallet finanziato su

Sepolia non paga nulla.

Free demo

demo_free returns one real LLM answer without payment, so an agent can verify the whole flow before funding a wallet.
