Agent Central

Ads change history

get_ads_change_history

Read-only

Returns Amazon's console change-history events for Sponsored Products and Sponsored Brands (the Seller Central History tab, last 90 days). IMPORTANT: changes made through the API, including every change agentcentral makes, do NOT appear here, so this is typically empty for agent-managed accounts. To see changes agentcentral made use get_action_history; to detect any Sponsored Products campaign-setting change regardless of source use get_campaign_snapshots with view=changes. Amazon does not include who made the change and does not return Sponsored Display changes.

Input Schema

Name	Required	Description	Default
`limit`	No	Max rows (1-1000, default 20).
`offset`	No	Pagination offset (0-100000, default 0). Use the returned pagination.next_offset to continue.
`keyword`	No	Filter by keyword text from event metadata.
`sort_by`	No	Column to sort by.	event_timestamp
`end_date`	No	Optional. YYYY-MM-DD upper bound on event_date. Defaults to today.
`entity_id`	No	Filter by changed entity ID.
`profile_id`	No	Filter by Amazon Ads profile ID.
`sort_order`	No	Sort order.	desc
`start_date`	No	Optional. YYYY-MM-DD lower bound on event_date. Defaults to 30 days ago.
`ad_group_id`	No	Filter by ad group ID from event metadata.
`campaign_id`	No	Filter by campaign ID from event metadata.
`change_type`	No	Filter by Amazon change type, for example STATUS, BUDGET_AMOUNT, BID_AMOUNT, or NAME.
`entity_type`	No	Filter by Amazon Ads change-history entity type.
`include_raw_rows`	No	For tabular results, false returns compact rows capped at MCP_TEXT_ROW_PREVIEW_LIMIT (default 10), regardless of limit. Complete-page and custom non-tabular responses may ignore this option; see tool-specific notes. Default true; large full-row responses are capped separately. Freshness fields require include_diagnostics=true in either row mode, where supported.
`include_diagnostics`	No	True enables expanded freshness diagnostics. Where supported, snapshot_capture_at and snapshot_data_through_date are populated only when include_diagnostics=true, in both compact and full-row modes; values may still be null if source data is unavailable. Default false. Basic empty-result data-window diagnostics are included by default when available.

AddedOct 7, 2026

TDQS

A4.7/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover safety (readOnlyHint=true, destructiveHint=false, openWorldHint=false), and the description goes well beyond them by disclosing the data-source gap (API-made changes and all agentcentral changes are absent), the 90-day window, the missing actor attribution, and the omission of Sponsored Display. Those are precisely the behavioral limits that would otherwise cause an agent to misread an empty result as 'no changes occurred'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose and scope come first, then the critical exclusion, then the two alternative tools in a single sentence. Every clause carries load-bearing information and there is no filler or restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has 15 optional parameters, a full output schema, and read-only annotations, so return shape, pagination, and safety are already covered elsewhere. The description supplies the only thing structured fields cannot: that results are sourced from Amazon's console, are typically empty, omit actor identity, and exclude Sponsored Display.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and every one of the 15 parameters carries its own documentation, including enum values and defaults, so the schema does the heavy lifting and a baseline 3 applies. The description adds only an implicit reconciliation of the date bound ('last 90 days') against start_date/end_date defaults, without discussing filtering or sort behavior beyond what the schema states.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Returns Amazon's console change-history events for Sponsored Products and Sponsored Brands') and bounds the scope to the Seller Central History tab over the last 90 days. It also names the exact cases where it is the wrong tool, so an agent can distinguish it from get_action_history and get_campaign_snapshots without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit routing: use get_action_history for agentcentral-made changes, and get_campaign_snapshots with view=changes for any Sponsored Products campaign-setting change regardless of source. It also flags that the tool is 'typically empty for agent-managed accounts', which is exactly the when-not-to-use signal an agent needs before spending a call.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
