Variations

get_variations
Read-only

Get parent/child variation relationships for an ASIN. Shows the variation family tree including variation theme (size, color, etc.) and all child ASINs.

Input Schema

NameRequiredDescriptionDefault
asinYesParent or child ASIN to look up variation relationships for
include_raw_rowsNoFor 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_diagnosticsNoTrue 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.

  4. Added

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful behavioral context about the variation family tree, variation theme, and child ASINs, but does not discuss limitations, empty results, pagination, or freshness.

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 description is two sentences with no wasted wording, and the core purpose is front-loaded. It is appropriately sized for a simple lookup tool.

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

Completeness4/5

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

Given the low complexity, rich input schema, annotations, and output schema, the description is nearly complete for correct invocation. It could mention edge cases such as missing variation relationships, but no critical information is absent.

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 the input schema already documents the asin parameter, including that it may be a parent or child ASIN. The description reinforces the relationship lookup but adds no syntax or format details beyond the schema.

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?

The description states a specific verb and resource: get parent/child variation relationships for an ASIN. It also specifies the returned content as a variation family tree with variation theme and child ASINs. It does not explicitly distinguish this from related sibling tools such as get_product_details, so it falls short of a 5.

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?

Usage is implied by the purpose: call this when variation relationships for an ASIN are needed. However, the description gives no explicit when-to-use guidance, exclusions, or alternatives such as get_product_details.

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