AdsAgent — Google Ads MCP

google_ads_insights_overview_query

Read-only

Ledger-backed insights overview for one scope. Defaults to 20 visible rows; summary/total covers the full filtered scope. A name search for an ad, campaign, or creative belongs to entities_lookup_by_name, not this overview.

TDQS

C2.9/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral facts beyond that: default 20 visible rows and the fact that summary/total covers the full filtered scope rather than the page. However, it leaves the meaning of "ledger-backed" and the cached-consistency behavior unexplained.

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?

Three short sentences with no filler, and the scope statement plus the pagination-vs-total behavior are front-loaded where an agent will read them. The middle sentence about rows and totals is somewhat compressed but earns its place.

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 17-parameter analytical query tool with near-zero schema descriptions, the description is far too thin; most parameters and the effect of grouping/daily view modes go unexplained. An output schema exists, so return-value documentation is not required, but the input-side gaps remain substantial.

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

Parameters2/5

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

Schema description coverage is only 6% across 17 parameters, so the description must carry the burden and does not. It only implies page_size (20 rows default) and alludes to search behavior; group_by, view_mode, date_from/date_to, window_days, require_complete_range, sort_key/sort_dir, connection_context, and channel_type are left entirely to bare enum/type declarations.

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

Purpose3/5

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

"Ledger-backed insights overview for one scope" gives a resource (insights overview) but "ledger-backed" and "one scope" are undefined jargon, so the actual operation is only implied. It does name one sibling it is not (entities_lookup_by_name), but it does not distinguish itself from google_ads_insights_overview_batch, google_ads_insights_query_daily, or insights_query_consistent, which are the closest alternatives.

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 description supplies one explicit exclusion with a named alternative: name searches for ads, campaigns, or creatives belong to entities_lookup_by_name. That is genuine routing guidance, but there is no positive statement of when to use this tool, no prerequisites, and no guidance versus the daily/batch/consistent insights siblings.

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