setlist_search_countries

Read-only

List all countries supported by setlist.fm with their ISO country codes, providing the code needed to search setlists by country.

Instructions

List all countries supported by setlist.fm, with their ISO country codes. Use a code as countryCode in setlist_search_setlists. 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

TableJSON 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.

TDQS

A4.2/5.0
Behavior4/5

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

Beyond the readOnlyHint annotation, the description discloses an important behavioral requirement: results must be presented as clickable setlist.fm source links because API terms require followable attribution, with a fallback to https://www.setlist.fm when no url exists. This is useful operational context not visible in the annotations.

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 sentences, each earning its place: purpose and output, downstream usage, and attribution requirements. The information is front-loaded with the core listing behavior before moving to usage and presentation rules. No redundant or filler content.

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 simple read-only tool with no required parameters and no output schema, the description covers the essential return content (countries, ISO codes, URLs) and the key follow-up action. It could be more explicit about the exact response container or pagination, but for 'list all countries' the guidance is sufficient.

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?

The single `view` parameter is already fully documented in the schema, including compact/full behavior and the explicit no-field-projection caveat. The tool description does not add parameter-level detail, so the baseline of 3 for high schema coverage applies.

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 states a specific verb and resource: 'List all countries supported by setlist.fm, with their ISO country codes.' This clearly differentiates the tool from siblings like setlist_search_cities or setlist_get_venue, and the mention of ISO codes adds concrete output expectations.

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?

The description gives clear downstream context: 'Use a code as countryCode in setlist_search_setlists.' This tells an agent why and how to apply the result. It does not explicitly name alternatives or exclusions, but the usage context is strong enough for the intended workflow.

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