Agent Central

Action history

get_action_history

Read-only

Return the tenant-wide audit log of changes agentcentral made (bids, budgets, keywords, negatives, targets, states, listings, and other writes), newest first. This is the reliable record of what the agent changed and when, including for reconstructing what changed around a performance shift; Amazon's own change history (get_ads_change_history) does not include API/agentcentral changes. Requires the active API key to include agent_actions:read; if allowed, returns actions submitted by all keys in this tenant, not just the caller key.

Input Schema

Name	Required	Description
`asin`	No	Optional ASIN filter for historical audit rows that populated asin.
`limit`	No	Maximum rows to return, newest first (1-500, default 100).
`domain`	No	Optional write domain filter. Currently audited write actions are in ads, catalog, and fulfillment.
`offset`	No	Pagination offset (0-100000, default 0). Use the returned pagination.next_offset to continue.
`target`	No	Optional substring match against the audit target field, such as campaign:123, keyword:456, or listing:SKU:price.
`end_date`	No	Optional YYYY-MM-DD upper bound for action timestamp. Defaults to today.
`tool_used`	No	Optional exact MCP write tool name filter.
`profile_id`	No	Optional Amazon Ads/Seller profile ID filter.
`start_date`	No	Optional YYYY-MM-DD lower bound for action timestamp. Defaults to 30 days ago.
`action_type`	No	Optional exact audit action type filter.

Output Schema

Name	Required	Description	Default
`evidence`	No

AddedOct 7, 2026

TDQS

A4.5/5.0

Behavior4/5

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

Annotations already cover the read-only, non-destructive, closed-world profile, and the description adds real context beyond them: a required permission scope (agent_actions:read), the fact that results span all API keys in the tenant rather than just the caller's, and newest-first ordering. It stops short of describing volume limits or truncation behavior, but the output schema covers pagination.

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?

Three sentences, front-loaded with what the tool returns and what it is reliable for, followed by the sibling comparison and the auth caveat. No sentence is filler and the most decision-relevant facts come first.

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?

For a 10-parameter read tool with full schema coverage and an output schema, the description supplies the missing decision-critical context: permission requirement, tenant-wide result scope, and the reason to prefer it over the Amazon-native alternative. Nothing needed to call it correctly 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 every parameter including asin, target, tool_used and the date bounds is already documented with format and defaults. The description reinforces date scoping and the write categories the filters operate over, but adds no syntax or semantics the schema does not already provide; baseline 3 applies.

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 the tenant-wide audit log of changes agentcentral made, enumerating the write categories (bids, budgets, keywords, negatives, targets, states, listings). It explicitly distinguishes itself from the closest sibling, get_ads_change_history, by noting that Amazon's history excludes API/agentcentral writes.

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?

Gives a concrete use case (reconstructing what changed around a performance shift) and names the alternative tool while explaining why it is insufficient for this purpose. An agent can decide between this and get_ads_change_history without opening either schema.

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