Agent Central

Audience segments

get_audience_segments

Read-only

Discover available Amazon Ads audience IDs for a profile from targetableEntities/list, with optional text and category-path search. The live endpoint's taxonomy is returned in category; type is often AUDIENCE, and Amazon may omit name, provider, status, and description.

Input Schema

Name	Required	Description
`query`	No	Optional free-text search for audience segment names, descriptions, types, or categories.
`next_token`	No	Amazon pagination token from a previous response.
`profile_id`	No	Numeric Amazon Ads profile ID. Optional when this API key has exactly one enabled Ads profile; agentcentral will default it. Call get_account_info for amazon_ads.enabled_profile_ids. Do not use the marketplace ID, tenant ID, or API key prefix.
`max_results`	No	Maximum number of audience segments to return. Defaults to 25.
`segment_types`	No	Deprecated legacy filter. segment_types is deprecated for get_audience_segments on targetableEntities/list. Use category_path_contains to filter Amazon's current category taxonomy.
`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.
`category_path_contains`	No	Optional case-insensitive substring filter against Amazon's category path, for example 'Custom-built > Product'.

Output Schema

Name	Required	Description	Default
`evidence`	No

TDQS

A3.5/5.0

Behavior4/5

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

Annotations already cover read-only and open-world safety, so the bar is lower, and the description adds real value: it discloses that the live endpoint returns taxonomy in category, that type is often AUDIENCE, and that Amazon may omit name, provider, status, and description. That warning about sparse fields prepares an agent for partial results in a way the annotations cannot.

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

Conciseness3/5

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

Two sentences with no filler, but they are dense and the second sentence packs several loosely related facts (taxonomy field, likely type value, omitted fields) without clear ordering. It is efficient but not maximally scannable.

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

Completeness3/5

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

With an output schema and fully described parameters, the definition is nearly sufficient, and the sparse-field warning fills the main gap. However, it says nothing about pagination behavior via next_token or how max_results interacts with the response size, which matters for an 8-parameter listing tool.

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%, so every parameter including query, category_path_contains, segment_types, and include_diagnostics is already documented in detail. The description only gestures at "optional text and category-path search" without adding syntax or formatting detail beyond the schema, so the baseline 3 applies.

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

Purpose4/5

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

"Discover available Amazon Ads audience IDs for a profile" gives a concrete verb plus resource, and naming the targetableEntities/list source tells an agent exactly what data backs the result. It does not explicitly contrast itself with nearby targeting tools such as get_sp_targeting_options, but the resource is specific enough to identify.

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

Usage Guidelines3/5

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

The mention of "optional text and category-path search" implies how to narrow results, but there is no explicit when-to-use/when-not-to-use guidance and no statement about alternatives among the many sibling get_* tools. Usage must largely be inferred from the resource name.

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