Get Amazon Subscribe & Save offer status, historical snapshots, and Amazon-provided Subscribe & Save metrics.

Input Schema

Name	Required	Description	Default
`skus`	No	Filter metrics by SKU where Amazon supports SKU filters.
`view`	No	Data view. Defaults to offers, or offer_history when start_date/end_date is provided without a view. Use offer_metrics for ASIN/SKU metrics and seller_metrics for seller/brand-level retention and revenue metrics.
`asins`	No	Filter by specific ASINs. Live offers are capped at 20 ASINs per call; metrics support depends on Amazon's view/filter rules.
`limit`	No	Max rows to return (1-500, default 20). Live offers are capped at 100 by Amazon.
`offset`	No	Pagination offset (0-100000, default 0). Use the returned pagination.next_offset to continue.
`metrics`	No	Optional Amazon metric allowlist for seller_metrics. Omit for Amazon's default/all metrics unless using ASIN/SKU/fulfillment filters.
`end_date`	No	Optional. YYYY-MM-DD. Defaults to today for offer_history and metrics views.
`start_date`	No	Optional. YYYY-MM-DD. For offer_history, reads stored snapshots. For metrics views, defaults to a 30-day window ending at end_date/today.
`brand_names`	No	Filter seller_metrics by brand name where Amazon supports brand filters. Retention metrics are brand-filterable for US marketplace data.
`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.
`time_period_type`	No	Metrics period type for offer_metrics and seller_metrics.	PERFORMANCE
`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.
`aggregation_frequency`	No	Metrics aggregation frequency for offer_metrics and seller_metrics.	WEEK
`fulfillment_channel_types`	No	Filter metrics by fulfillment channel type where supported.

AddedOct 7, 2026

TDQS

C2.9/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so safety behavior is covered. The description adds only that data includes historical snapshots and Amazon-provided metrics, but omits freshness, pagination, row limits, and how diagnostics flags affect results.

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

Conciseness4/5

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

The description is a single front-loaded sentence with no wasted wording. It is concise and readable, though its brevity leaves important orientation for a complex tool to other fields.

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

Completeness2/5

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

For a tool with 14 parameters, four views, and multiple metrics modes, one purpose sentence is not enough to orient the agent. The output schema and parameter descriptions help, but the description should still explain view selection, date defaults, and snapshot versus metrics behavior.

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 schema fully documents the 14 parameters. The description adds no parameter-level meaning beyond that, which meets the baseline when the schema carries the load.

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 uses a specific verb ('Get') and names the exact resource ('Amazon Subscribe & Save'), plus three data categories: offer status, historical snapshots, and metrics. This clearly separates it from generic performance or promotion tools, though it does not explicitly contrast any sibling tool.

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

Usage Guidelines2/5

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

There is no explicit when-to-use guidance, no mention of choosing among the four schema views, and no alternatives or prerequisites. Usage is only implied by the domain-specific purpose.

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