Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to mazzagrp.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP endpoint exposing 23 pay-per-call AI APIs, billed in USDC on Base via the x402 protocol with no API keys or signup.

What you can do: Call a free demo tool that returns one real LLM answer without payment
Generate and analyze spreadsheet formulas, SQL queries, and long-form answers
Run creative and simulation tasks: stories, worldbuilding, characters, puzzles, design suggestions
Get advisory output on negotiation, event operations, workflow automation, and AI strategy consultation
Retrieve memory context, run RAG queries, compare models, and assess MCP implementations
When to use it: Worth adding when an assistant should reach a menu of hosted AI capabilities without managing API keys, and the caller is set up to pay small per-call USDC amounts on Base. The free demo tool lets you test the payment flow before funding a wallet.
Requirements: A remote streamable HTTP endpoint; nothing to install. A client that can handle the x402 payment flow with its own funded wallet on Base mainnet (USDC), since the first call returns HTTP 402 and must be retried with a PAYMENT-SIGNATURE header. A legacy local stdio package exists that needs Python and a wallet key or wallet file.

Before you install

Every tool except the free demo costs real money per call, from about $0.10 up to $15.00, settled in USDC on Base mainnet rather than a testnet. The legacy stdio package asks for a wallet private key through MAZZAGRP_WALLET_KEY or a wallet file via MAZZAGRP_WALLET_PATH, which is a high-value secret; the remote server does not hold keys. Tool calls send your prompts to a third-party service.

Installation

In SourceWeft

Open Mazza Group AI APIs in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.mazzagrp%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

mazzagrp-mcp

[MCP] [x402] [Registry] [mcptry] [License: MIT] [Python 3.10+]

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.

Registry name: com.mazzagrp/mcp
Remote endpoint: https://mazzagrp.com/mcp (streamable HTTP)
Discovery: /.well-known/x402.json · /.well-known/mcp/server-card.json · agents.md

Use the remote server (recommended)

Nothing to install. Point your client at the URL:

json

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

{  "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)

json

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

{  "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.

How payment works

The agent calls a tool.
The API replies HTTP 402 with the x402 v2 requirements (accepts[0].amount, network eip155:8453).
The client signs an EIP-712 authorisation with its own wallet.
It retries with the PAYMENT-SIGNATURE header.
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.
