PayGate MCP — Monetization Gateway for AI Agents

Find a paid tool that does something you cannot do yourself. Use when the user needs a capability you lack and is willing to pay per use, or asks what paid tools, APIs or data sources are available. Returns every tool on the market with its price per call in USD and the endpoint to call it. Browsing is free and needs no key.

Start charging for an MCP server the user owns. Use when they want to monetize, sell, charge for, get paid for, put a price on, or make money from a server, API or tool. Buyers pay their wallet DIRECTLY on-chain — PayGate never holds the money, so there is no payout to wait for, no balance to withdraw and no commission taken. Their server is never modified and needs no payment code. Tools are imported automatically, so it must be publicly reachable over HTTPS and answer tools/list. Returns a proxy URL and a secret api_key shown only once; save it, every other seller tool needs it.

Reprice or unlist something the user already sells. Use when they want to raise, lower or change a price, make a tool free, pause selling it, or take it off the market. Requires the api_key from register_server.

{
  "type": "object",
  "properties": {
    "api_key": {
      "type": "string",
      "description": "Your seller key."
    },
    "tool_name": {
      "type": "string",
      "description": "Exact name of the tool to update."
    },
    "price_usd": {
      "type": "number",
      "description": "New price per call in USD. Minimum 0.01."
    },
    "is_active": {
      "type": "boolean",
      "description": "Set false to stop selling this tool."
    }
  },
  "required": [
    "tool_name"
  ]
}

Report how much the user has earned selling their tools. Use when they ask about sales, revenue, income, how much they made, how many calls were paid, or which tool sells best. Returns paid calls, gross revenue, commission and net revenue, broken down per tool. Requires the api_key from register_server.

{
  "type": "object",
  "properties": {
    "api_key": {
      "type": "string",
      "description": "Your seller key."
    }
  }
}

Review what the user currently has for sale. Use when they ask what they are selling, what their prices are, where their money goes, or want to check their listing before changing it. Returns the proxy URL, payout destination, commission rate and every listed tool with its price. Requires the api_key from register_server.

{
  "type": "object",
  "properties": {
    "api_key": {
      "type": "string",
      "description": "Your seller key."
    }
  }
}

Prove the user owns the server they listed, earning a trusted badge in the marketplace. Use after they have published their verification token at /.well-known/paygate-verify on the server's domain. PayGate fetches that URL and confirms the token matches. Verified sellers can be filtered for by buyers, so this directly increases how often their tools get chosen. Requires the api_key from register_server.

{
  "type": "object",
  "properties": {
    "api_key": {
      "type": "string",
      "description": "Your seller key."
    }
  }
