get_saved_albums

Retrieve albums saved in your Spotify library. Use fetch_all to get your entire collection, with pagination controls for larger libraries.

Instructions

Get albums saved in the user's library. Set fetch_all=true to retrieve the entire collection. Output is capped by max_results (default: SPOTIFY_MCP_MAX_ITEMS).

TDQS

A3.8/5.0
Behavior3/5

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

With no annotations provided, the description carries the full behavioral burden. It discloses two meaningful behaviors: fetch_all=true retrieves the entire collection, and output is capped by max_results with a default. This is useful but does not cover other behavioral aspects like return format nuance, pagination interaction beyond fetch_all, or auth/scope requirements, leaving some gaps.

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?

Two sentences deliver the core purpose and the two most important behavioral nuances (fetch_all and max_results cap) with zero filler. The most decision-relevant information is front-loaded, making it easy for an agent to parse quickly.

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

Completeness4/5

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

For a six-parameter read tool with no output schema and no annotations, the description covers the key invocation decisions: whether to fetch all, and the cap on results. The schema already documents limit, offset, market, and response_format, so nothing needed to call the tool correctly is missing. The lack of an output schema is mitigated by the tool's self-descriptive 'albums' return type, though richer return details would be nice.

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 baseline is 3. The description adds minimal value beyond the schema: it restates the fetch_all behavior and max_results cap that are already documented in the schema. No parameter meaning is missing, but the description does not significantly enrich what the schema already provides.

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 opens with 'Get albums saved in the user's library', which clearly specifies the verb, resource, and scope. This differentiates it from catalog lookups like get_album or get_several_albums by anchoring on the user's saved library, and from related saved-item tools by being specifically about albums.

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 gives usage context ('albums saved in the user's library') and operational guidance about fetch_all and max_results. However, it does not explicitly compare with search_saved_albums or other saved-item retrieval tools, so an agent may not know when to choose this over a sibling. Usage is implied rather than clearly delimited.

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