setlist_get_setlist_version

Read-onlyIdempotent

Retrieve a specific historical version of a setlist by version ID to inspect songs, sets, encores, covers, guests, and notes from that wiki edit.

Instructions

Get a specific historical version of a setlist by its version ID. Setlists are wiki-edited; each edit has a version ID returned in a setlist's versionId field. A setlist's songs live in sets.set[]; each set may have an encore number (1 = first encore) and a name (e.g. an acoustic set or a full album). Each song may carry: tape: true (pre-recorded intro/outro/interlude — not actually performed), cover (the original artist when it is a cover), with (a guest performer), and info (a note like "acoustic" or "first time live"). Results include a setlist.fm url; when you present this data, cite it as a clickable source link to setlist.fm (their API terms require followable attribution — no nofollow). If a result has no url, link to https://www.setlist.fm instead.

Input Schema

NameRequiredDescriptionDefault
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Setlist.fm's payload untouched. No field projection: this server has no verified record of which Setlist.fm fields matter, and inventing one would risk dropping a field a caller needs.

A4.2/5.0
Behavior5/5

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

With no output schema, the description carries the burden of disclosing what comes back: sets.set[] structure, encore numbering, set names, and per-song flags (tape, cover, with, info). It also adds a non-obvious contractual obligation (attribution must be a followable link, no nofollow) that no annotation conveys.

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?

Purpose is front-loaded in one sentence, followed by domain field semantics that each earn their place. The attribution paragraph is slightly long but is a compliance requirement 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?

For a read-only lookup with no output schema, the description covers purpose, how to obtain the ID, the shape and meaning of returned fields, and the required citation behavior — nothing an agent needs to call or present this correctly is missing.

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%, including a detailed enum explanation for view, so the schema already documents both parameters. The description adds only the provenance of versionId, not syntax, format, or ID-shape guidance beyond what the schema states.

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 (Get), resource (setlist version) and narrowing qualifier (a specific historical version, by version ID). The word 'historical' implicitly separates it from sibling setlist_get_setlist, which returns the current version.

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?

Explains where the required versionId comes from ('each edit has a version ID returned in a setlist's versionId` field'), which is real usage guidance for obtaining the parameter. However it never states when to prefer this over setlist_get_setlist, nor any exclusions or prerequisites.

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