MCP support
It provides MCP tools for searching and discovering Macaroon Network products and servers, inspecting sources, and executing products. Paid execution returns an x402 challenge for the caller's wallet infrastructure to sign.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

| Parameter | Type | Required | Description |
|---|---|---|---|
| query | string | Yes | Name to screen, for example 'Vladimir Putin' or 'Banco Nacional de Cuba'. |
| payment_signature | string | No | Only set this after a prior call returned x402_payment_required and you've since signed the exact-scheme USDC payment it described with your own wallet -- set it to the resulting signed proof. Omit on a first attempt. |
Details
From the project READMEmacaroonnetwork-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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
