Call this server's tools from your browser. Nothing to install.

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.

register_server

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.

Argument	Type	Description
name*	string	Display name of the service in the marketplace.
email	string	Optional contact address.
wallet_address	string	EVM address that receives USDC on Base. Required unless stripe_account_id is given.
default_price_usd	number	Price per call applied to every imported tool. Defaults to 0.02.
stripe_account_id	string	Stripe Connect account (acct_...) to receive fiat instead. Only for tools priced at $0.50 or above.
target_server_url*	string	Public HTTPS URL of the MCP server to monetize, e.g. https://example.com/mcp

Input schema (JSON)

set_tool_price

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.

Argument	Type	Description
api_key	string	Your seller key.
is_active	boolean	Set false to stop selling this tool.
price_usd	number	New price per call in USD. Minimum 0.01.
tool_name*	string	Exact name of the tool to update.

      "description": "Exact name of the tool to update."
    }
  }
}

verify_ownership

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.

Argument	Type	Description
api_key	string	Your seller key.
