Get Google Analytics dimensions and metrics

analytics_get_fields

Read-onlyIdempotent

Every dimension and metric one Google Analytics 4 property reports, with the api_name analytics_get_report takes, custom dimensions and metrics included.

Use when: a report needs a field outside the common ones, "what custom dimensions do we track", checking a conversion or event-scoped field's name before asking for it, or after analytics_get_report rejected a field name. Not for: the numbers themselves, use analytics_get_report. Returns: List, dimensions then metrics, in Google's order. rows[]: kind (dimension | metric), api_name, ui_name, description, category, custom (defined on this property: customEvent:x, customUser:x), metric_type (metrics only: TYPE_INTEGER, TYPE_FLOAT, TYPE_SECONDS, TYPE_CURRENCY and so on). Several hundred rows; filter with custom or category. Cost: 0 credits. Cached 1 day. Example: {"property": "properties/123456789", "limit": 1000}

Behavior5/5

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

Annotations cover read-only/idempotent/open-world safety, but the description goes further with cost (0 credits), caching (1 day), and result volume (several hundred rows, filter by custom or category) — operational traits no annotation conveys. It also discloses the exact row shape (kind, api_name, ui_name, category, custom, metric_type).

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?

Front-loaded with the core purpose and organized into Use when / Not for / Returns / Cost / Example sections, so it scans well. It is on the long side, but nearly every line carries actionable information rather than filler.

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?

An output schema exists, yet the description still summarizes the return contract and pagination/volume considerations, plus cost and cache behavior for a read-only tool with a single required parameter. Nothing an agent needs to call it correctly is missing.

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

Parameters4/5

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

Schema description coverage is 100%, so the baseline is 3, but the description adds a concrete call example ({"property": "properties/123456789", "limit": 1000}) and notes filtering by custom/category, giving practical invocation context beyond the schema.

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 precise verb+resource (fetch every dimension and metric a GA4 property reports) and explicitly links the returned api_name to what analytics_get_report consumes. It is distinguishable from analytics_get_report and analytics_list_properties without opening either schema.

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?

Explicit 'Use when' block enumerates concrete triggers (field outside the common ones, listing custom dimensions, checking a conversion/event-scoped field name, recovering from a rejected field). The 'Not for' clause names the alternative (analytics_get_report) and the condition that selects against it.

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