Get a brewery's beer list

untappd_brewery_beers
Read-onlyIdempotent

Get beers from a brewery by its Untappd ID, including ratings, check-in counts, and sortable or pageable results.

Instructions

Get the beers a brewery makes, by brewery id, with per-beer rating and check-in counts. Supports sorting and paging. Get an id from untappd_search_brewery. Read-only.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sortNoSort order (default by popularity)
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact keeps each beer's identity, rating and counts and drops the description, label URLs and the copy of this brewery repeated on every row; "full" returns Untappd's whole page.
limitNoMax beers (1–50, default 25)
offsetNoResult offset for paging (default 0)
brewery_idYesUntappd brewery id

A4.3/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, and open-world behavior, and the description reaffirms read-only without contradicting them. It adds useful behavioral context: the response carries per-beer ratings and check-in counts, and the call supports sorting and paging.

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 short sentences front-load the core operation and returned data, then provide the prerequisite and safety note. No redundant words or unnecessary repetition of schema details.

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 read-only list tool, the description covers the resource, the key parameter, how to obtain that parameter, what data to expect, and pagination/sorting behavior. Combined with the full schema and annotations, an agent has everything needed to call it correctly.

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 coverage is 100% and each parameter already has a meaningful description, so the description does not need to compensate. It adds only a general 'sorting and paging' note and the brewery_id source, which mildly supports but does not significantly extend 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?

The description names a specific action ('Get') and resource ('the beers a brewery makes'), scoped by brewery_id, and clarifies the payload includes per-beer rating and check-in counts. This clearly distinguishes it from sibling tools like untappd_brewery_info and untappd_search_beer.

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

Usage Guidelines4/5

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

It gives a clear prerequisite: obtain the brewery_id from untappd_search_brewery, and states that sorting and paging are available. It doesn't explicitly list exclusions or alternative tools, but the context is strong enough to route usage.

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