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.
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.When a product needs payment, macaroons_execute returns an
x402_payment_required result instead of hiding the challenge:
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.
The default registry is https://api.macaroonnetwork.com. For local
development, override it with MACAROONS_REGISTRY_URL.
