Amazon Ads changes

Add Ad Keywords

Add keywords with bids to a Sponsored Products ad group.

This tool changes your Amazon Ads account

add_ad_keywords adds keywords to your Amazon Ads account. Changes apply right away in your Amazon Ads account. Launch Fast records each change with what changed, when, and which AI app made it. To undo a change, ask your AI app to undo it. It uses undo_ad_change. Launch Fast tells the assistant to confirm each change with you first, unless you named the change exactly. Your AI app may also ask before it runs a change tool.

Field	Value
MCP tool	`add_ad_keywords`
Behavior	Makes a change in your Amazon Ads account. Marked destructive, so your AI app may ask before it runs. It adds keywords and does not remove or replace anything, but a new keyword can start spend at once.
Cost	Free

Sign-in	OAuth only. API keys cannot make Ads changes. Your last Amazon verification (the code from your authenticator app) must be from the last 30 days.
Ad type	Sponsored Products only
Amazon connection	Amazon Ads
App view	None. The assistant shows the result as text and a table.

What It Does

add_ad_keywords adds keywords to one Sponsored Products ad group. Each keyword has a match type (exact or phrase) and a bid. One call takes up to 100 keywords.

When To Use It

Use it to harvest a search term that sold. Find these terms in the search term report or in the harvest list of an Ads diagnostic. To build a full new campaign, use create_ad_campaign.

Inputs

Input	Required	Values	Example
`campaign`	Yes	The campaign name, or its `campaign_id`	`SP Garlic Exact`
`ad_group`	When the campaign has more than one ad group	The ad group name	`Garlic Press Exact`
`keywords`	Yes	A list of 1 to 100 keywords	See the rows below
`keywords[].keyword`	Yes	The keyword text	`garlic press stainless`
`keywords[].match`	Yes	`exact` or `phrase`	`exact`
`keywords[].bid`	Yes	The bid, more than 0	`0.90`
`marketplace`	No	Two letters, such as `US`, `CA`, `UK`, or `DE`. Give it only when you advertise in more than one marketplace.	`US`
`reason`	No	One line on why, up to 300 characters. Launch Fast saves it with the change. The default is "Asked for in chat."	`Add search terms that sold`

What The Answer Contains

A status: applied, partly applied, not applied, going through, or unconfirmed.
A table with the keywords added to the campaign, and the result.
The change id (it starts with ac-). Use it with get_ad_changes and undo_ad_change.
Notes about large changes, and the currency when it is not USD.
The day that the result is due. Ask for it then with get_ad_changes. Launch Fast compares the two weeks before the change with the two weeks after it, so the result shows about three weeks later.

Status	Meaning
`applied`	All changes reached Amazon Ads.
`partly applied`	Some changes reached Amazon Ads. The table shows what happened to the rest.
`not applied`	Nothing changed in Amazon Ads. The table shows why.
`going through`	Amazon was still applying the change when the answer came back. The answer waits up to 45 seconds. Launch Fast keeps applying the change, and if the call was cut off, it carries the change on within about 15 minutes. Check it in a minute with `get_ad_changes`.
`unconfirmed`	Amazon accepted the change but then showed a different value. Check the value in Amazon Ads before you change it again.

Example Prompts

Add "garlic press stainless" as an exact-match keyword in SP Garlic Press at $0.90.

Add my three best search terms from last month as exact-match keywords. Bid their average cost for each click.

Common Errors

Error	What it means	What to do
`invalid_input`: Amazon Ads will not take these keywords	A keyword is in the ad group now, is listed twice, breaks an Amazon rule, or has a bid outside Amazon's minimum or maximum for the marketplace. The answer names each keyword and the cause.	Remove those keywords. The answer gives the call without them.
`invalid_input`: match is `exact` or `phrase`	A keyword has no match type, or it has `broad`.	Give `exact` or `phrase`.
`invalid_input`: say which ad group	The campaign has more than one ad group.	Add `ad_group`.
`invalid_input`: more than 100 items	The call has more than 100 keywords.	Put the rest in another call.
`not_found`	No Sponsored Products campaign has that name, or the campaign has no ad group with that name. The answer lists similar campaign names, or the ad groups of the campaign.	Use a name from the answer, or find it with `amazon_ads_entity_graph_lookup`.
`oauth_required`	You connected Launch Fast with an API key. API keys cannot change Amazon Ads.	Add Launch Fast as a connector in your AI app and sign in. See Getting started.
`mfa_required`	Your last Amazon verification is more than 30 days old, or Amazon access for this app ended.	Connect the app again and enter your authenticator code on the Launch Fast sign-in page. See Authentication.
`not_enabled`	Ad changes through Launch Fast are paused for now, or Amazon access for the app needs a fresh verification. The message says which.	For a fresh verification, verify again in Settings > MCP & API keys. For a pause, make the change in Amazon Ads.
`busy`	Another change on this Amazon Ads account is in progress.	Wait a minute and try again. Check the change with `get_ad_changes`.
Rate limit: `amazon_ads rate limit exceeded`	Your account made more than 10 Ads change calls in one minute. The limit counts all the change tools together.	Wait the number of seconds in the message, then try again.

add_negative_keywords adds the same search as a negative in your broad or auto campaign.
undo_ad_change removes the added keywords.
