Security Report
This MCP server for Macaroon Network demonstrates solid security practices with proper authentication via L402 macaroons, careful credential handling (no hardcoded secrets), and well-designed payment flow controls. The codebase properly isolates wallet operations with safe defaults ("none" mode requiring manual payment). Minor code quality concerns around broad exception handling and subprocess usage in external LND mode do not significantly impact the overall security posture. Permissions (network_http, env_vars, subprocess for optional external LND) are appropriate for the server's stated purpose of accessing a marketplace API and optionally controlling an external LND node. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue (1 critical, 0 high severity).

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.
