Nothing to run from here
ChangeNOW is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http changenow-mcp https://mcp.changenow.io/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

Find the assets ChangeNOW can exchange and turn what the user said into a canonical asset id. Search by ticker, name or network, filter by network, by fiat or crypto, and by whether a fixed rate is possible. Always call this before quoting: the same ticker exists on several networks and only the canonical id "ticker.network" identifies one of them. When has_more is false the response is the comple
| Parameter | Type | Required | Notes |
|---|---|---|---|
| q | string | no | Substring search over canonical id, legacy ticker, name and network. Case insensitive. Example: "usdt", "bitcoin", "tron". |
| network | string | no | Keep only assets on this network, for example "eth", "trx", "sol". |
| kind | string | no | crypto for swappable coins and tokens, fiat for currencies that can only start a purchase, all for both. |
| fixed_rate | boolean | no | Keep only assets the catalogue flags as fixed rate capable. The flag is a hint: a pair flagged false can still get a fixed rate, so confirm with quote_swap rather than filtering a user out. |
| popular | boolean | no | Return the short curated list. Use this to answer "what can I swap" without paging. |
| limit | integer | no | How many assets to return. Default 50, maximum 500. |
| cursor | string | no | Cursor from next_cursor of the previous page. Only needed when has_more is true. |
Everything needed to build a swap for one asset: the canonical id, the legacy ticker used in website links, decimals, whether a memo is required and what the receiving side calls it, the address format, the token contract and the warnings to relay to the user. Minimum and maximum amounts are not here because they belong to the pair, not to the asset: get them from quote_swap.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | yes | Canonical id "usdt.trx". A legacy ticker "usdttrc20" or a page slug "tether-trc20" is also accepted. |
Ask what a swap would give, in either direction: pass amount_from to learn what the user receives, or amount_to to learn what the user must send. Returns the rate, the pair minimum and maximum, who would execute the order, and the warnings to relay. With rate_type "fixed" it also returns the rate_id that create_swap needs; that lock lasts about two minutes, so quote again right before creating the
| Parameter | Type | Required | Notes |
|---|---|---|---|
| from | string | yes | Asset the user sends, canonical id, for example "btc.btc". |
| to | string | yes | Asset the user receives, canonical id, for example "usdt.trx". |
| amount_from | string | no | Amount the user sends, as a decimal string. Pass this or amount_to, never both. |
| amount_to | string | no | Amount the user wants to receive, as a decimal string. The answer then says how much to send. |
| rate_type | string | no | float: the rate is settled when the deposit arrives. fixed: the rate is held until valid_until, about two minutes, and returns the rate_id create_swap needs, usually at a slightly worse rate. Ask for |
| promo_code | string | no | Promo code to apply, if the user has one. |
Check a recipient address, and its memo when the asset needs one, against the format the network requires, before any order exists. Call this on every address the user gives. A valid-looking address on the wrong network is the one mistake in a swap that destroys the funds with no way back, so when the address belongs to another network the answer names that network instead of just refusing. A few
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | yes | Asset that will be received at this address, canonical id. |
| address | string | yes | Recipient address to check. |
| memo | string | no | Memo or destination tag, when the asset needs one. |
Build a changenow.io link with the pair, the amount, the recipient address and the memo already filled in, so the user checks the numbers on the real page and presses Confirm themselves. Opening the link creates nothing. This is the recommended way to finish a swap: the user sees the rate and the address with their own eyes, which no amount of care in a chat transcript can replace. Use create_swap
| Parameter | Type | Required | Notes |
|---|---|---|---|
| from | string | yes | Asset the user sends, canonical id. |
| to | string | yes | Asset the user receives, canonical id. |
| amount_from | string | no | Amount to prefill as the amount sent. |
| amount_to | string | no | Amount to prefill as the amount received. Implies a fixed rate on the page. |
| address | string | no | Recipient address to prefill. The user can still change it on the page. |
| memo | string | no | Memo or destination tag to prefill. |
| refund_address | string | no | Refund address to prefill. |
| rate_type | string | no | Which rate the page opens with. |
| locale | string | no | Two letter locale for the page, for example "es". English needs no locale. |
Create a real swap order and return the deposit address the user has to send funds to. This call moves no money by itself, but the order is real: it exists in support, it can expire, and a fixed rate is locked against it. Quote the swap first, validate the recipient address, and confirm the amount and the address with the user before calling this. If the user has not explicitly approved both, use
| Parameter | Type | Required | Notes |
|---|---|---|---|
| from | string | yes | Asset the user sends, canonical id, for example "eth.eth". |
| to | string | yes | Asset the user receives, canonical id, for example "usdt.trx". |
| address | string | yes | Address that receives the swapped asset. Check it with validate_address first; a wrong network here loses the funds. |
| amount_from | string | no | Amount the user sends. Pass this or amount_to, never both. |
| amount_to | string | no | Amount the user wants to receive. Requires rate_id from quote_swap. |
| memo | string | no | Memo or destination tag for the recipient address, when the asset needs one. |
| refund_address | string | no | Where the deposit returns if the swap cannot complete. Strongly recommended: without it a failed swap needs support. |
| refund_memo | string | no | Memo for the refund address. |
| rate_id | string | no | The rate_id from quote_swap with rate_type "fixed". Required for a fixed rate order. It holds for about two minutes, so quote again right before this call if the user needed time to decide. |
| contact_email | string | no | Optional email for status notifications about this order. |
| promo_code | string | no | Promo code to apply, if the user has one. |
Follow an existing order by id: where it stands, what the deposit and payout amounts turned out to be, the transaction hashes, and a plain-language explanation of what the current stage means and what happens next. Use it after create_swap, and again whenever the user asks where their swap is.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | Order id returned by create_swap. |
| sub_id | string | no | Sub order id, for an order the provider split in two. |

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 2.1.1.
