Tollkit MCP server

Pay-per-call tools for AI agents, as one remote MCP server:

https://api.tollkit.dev/mcp

No account and no API key. Each paid tool costs a fixed amount of USDC, paid per call with x402 on Base or Solana. A call that fails is never charged.

Listed in the official MCP Registry as io.github.UltraStarz/x402-extract.

Connect

Add the URL above as a remote (Streamable HTTP) MCP server in Claude, Cursor or any MCP client. In clients that take a JSON config:

{
  "mcpServers": {
    "tollkit": { "url": "https://api.tollkit.dev/mcp" }
  }
}

Paying: MCP has no 402 status, so a paid tool called without its payment argument returns the price quote as its result. Sign that quote with your x402 wallet and call the tool again with payment set. Six tools are always free: try_it_free (a real sample result), get_service_info, find_service, check_service, check_my_balance and verify_attestation. Fourteen give 3 free calls a day without a payment: read_page, screenshot_page, pdf_to_text, weather_forecast, airport_delays, geocode_address, exchange_rate, ip_lookup, wallet_balance, token_info, transaction_lookup, token_price, token_check and sec_company.

Without MCP

Every tool is also a plain HTTP endpoint: POST the JSON body, get HTTP 402 with the price, pay with any x402 client (for example @x402/fetch), repeat the request. OpenAPI per hostname, e.g. https://data.tollkit.dev/openapi.json.

This repo

server.json is the MCP Registry entry. src/ holds an older stdio client (the x402-extract-mcp npm package) that only wraps product extraction and is no longer maintained; use the remote server above instead.
