Common questions
Is Macaroon Network 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

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:
{"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.
