ChangeNOW MCP: quote and track crypto swaps from your AI app

Connect ChangeNOW to Claude, ChatGPT or Cursor

1. 1Click Connect ChangeNOW free. There's no sign-in, so its tools are ready at once.
2. 2`create_swap` creates a real order with a deposit address. It moves no money by itself, but if your AI app should only quote and check, switch it off and keep `quote_swap`, `validate_address` and `swap_link`.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask your AI app what 0.5 ETH would get you in USDC on another chain through ChangeNOW, then open Activity to see the `quote_swap` call.

Swap research from a chat

• Turn a ticker, name or network into ChangeNOW's canonical asset id with `list_assets`.
• Ask what a swap would give, or what you'd need to send, with `quote_swap`.
• Check a recipient address and memo against the network's format with `validate_address`.
• Build a prefilled changenow.io link with `swap_link`, so you check the numbers on ChangeNOW's own page before paying.
• Follow an existing order with `check_swap_status`.

Keep real orders a human decision

• Switch off `create_swap` and your AI app can still quote and build links, but can't open an order.
• Or leave it on with a policy that warns or blocks before an order is created.
• Activity records every ChangeNOW call your team's AI apps make.

What you get with ChangeNOW and ContextGate

• You choose which tools they can useSwitch off any ChangeNOW tool you don't want used. It's hidden from your AI apps and refused if called.
