Overview

AI-generated overview

A local MCP discovery router for the Macaroon Network marketplace, letting an assistant search products, inspect categories and sources, and run paid x402 USDC-

What you can do
Search sale-ready products by natural-language intent and retrieve freshness and content-hash metadata for a feed target. Retrieve the canonical category registry with mapped-product counts. Discover evidenced live Macaroon MCP servers and their transports. Retrieve reviewed source and rights records with partial-coverage reporting. Execute an x402 USDC product and receive the predicate-verified result and receipt.
When to use it
Use it when an assistant needs to find evidence-backed data products or MCP servers on Macaroon Network, or to run a paid product query through the x402 flow. The free discovery and metadata tools are useful on their own for browsing the marketplace.
Requirements
Runs locally as a stdio process, installed from PyPI (macaroonnetwork-mcp) and started with uvx or the macaroonnetwork-mcp command. Network access to the default registry at api.macaroonnetwork.com, overridable with MACAROONS_REGISTRY_URL for local development. No authentication is declared. Paying for products needs the caller's own wallet or Coinbase CDP infrastructure to sign the x402 challenge.
Before you install
Paid execution spends USDC on Base mainnet; the package never holds a wallet or signs payments, so the caller's own wallet infrastructure signs the exact x402 challenge and the signed proof is sent back on retry. Executing a product sends queries to the remote registry and may incur charges per successful query. Review the returned challenge amount and destination before signing.

Installation

In SourceWeft

  1. Open Macaroon Network in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

README

macaroonnetwork-mcp

MCP discovery router for Macaroon Network, a marketplace where agents find evidence-backed products and pay per successful query.

The payment rail exposed by this release is x402 using USDC on Base mainnet. The package never holds a wallet or signs a payment. It returns the exact x402 challenge for the caller's own wallet infrastructure to sign, then accepts that signed proof on the retry.

Tools

  • macaroons_search — search sale-ready products by natural-language intent. Free.
  • macaroons_metadata — retrieve free freshness and content-hash metadata for a feed target.
  • macaroons_categories — retrieve the canonical category registry and exact mapped-product counts. Free.
  • macaroons_discover_mcp — retrieve evidenced live Macaroon MCP servers and their transports. Free.
  • macaroons_sources — retrieve reviewed source and rights records, with explicit partial-coverage reporting. Free.
  • macaroons_execute — execute an x402 USDC product and receive the predicate-verified result and receipt.

Paying with x402

When a product needs payment, macaroons_execute returns an x402_payment_required result instead of hiding the challenge:

json
{  "x402_payment_required": true,  "resource_url": "https://api.macaroonnetwork.com/execute/...",  "amount_atomic": "3000",  "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",  "network": "eip155:8453",  "pay_to": "0x33cc...",  "extra_name": "USD Coin",  "extra_version": "2",  "max_timeout_seconds": 60,  "x402_version": 2}

Sign the exact payment described by the challenge with your own wallet or Coinbase CDP infrastructure. Then call macaroons_execute again with identical arguments plus payment_signature. x402 exact settlement uses one signed retry; there is no invoice-polling flow.

Install

bash
pip install macaroonnetwork-mcp

Use with an MCP client

json
{  "mcpServers": {    "macaroonnetwork": {      "command": "macaroonnetwork-mcp"    }  }}

The default registry is https://api.macaroonnetwork.com. For local development, override it with MACAROONS_REGISTRY_URL.
