Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

buy_credits

How to buy Neuronto credits, the one prepaid balance for every paid Neuronto call (searches past the free allowance, multi-step discovery, the change feed, publisher monitoring, gateway fees): the packs, what each thing costs, and the x402 URL to pay.

packstring

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

buy_credits

Argument	Type	Description
pack	string

Input schema (JSON)

{
  "type": "object",
  "properties": {
    "pack": {
      "enum": [
        "1",
        "5",
        "20",
        "50"
      ],

    }
  },
  "additionalProperties": false
}

facilitator_status

What this x402 facilitator can settle right now: the live networks and schemes, whether the echo merchant is serving, the state of address screening, observed availability and settlement counts. Call this before advertising a price, because a network that cannot settle is withdrawn here first.

No arguments.

Input schema (JSON)

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

find_paid_resource

Search the catalogue of resources that have been paid for through this facilitator: the URL, the terms, the method, and the input and output shapes where the merchant published them. A resource is listed only after a real settlement and a probe, so nothing here is a claim by its owner.

Argument	Type	Description
limit	integer
query	string	Words to match in the URL or description.
network	string	CAIP-2 network to restrict to.

Input schema (JSON)

{
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 50,
      "minimum": 1
    },
    "query": {
      "type": "string",
      "description": "Words to match in the URL or description."
    },
    "network": {
      "type": "string",
      "description": "CAIP-2 network to restrict to."
    }
  },
  "additionalProperties": false
}

integration_snippet

Working code to start charging for a route through this facilitator, in the language and framework you name, plus a live URL to test the client against. Copy it as it is; the only thing to change is the wallet.

Argument	Type	Description
role	string	server to charge for a route, client to pay for one.
language	string
framework	string

Input schema (JSON)

{
  "type": "object",

      "type": "string",
      "description": "server to charge for a route, client to pay for one."
    },

      ],
      "type": "string"
    }
  },
  "additionalProperties": false
}

monetize_api

Put an existing HTTPS API behind x402 without changing its code: returns a paid URL that answers 402 with your price, forwards paid calls to your API, and settles each payment straight to your wallet. 1,000 paid calls a month free, then 1% from prepaid credits. Pass your key, or omit it and a new one is returned.

Argument	Type	Description
key	string	Your Neuronto key (nc_ or nk_). Omit to get one.
name*	string	What buyers see, for example 'Weather API'.
pay_to*	string	Your EIP-55 checksummed wallet address.
upstream*	string	Your API's https base URL.
price_usd*	number	Price per call in US dollars, paid in USDC.
description	string
