Location and Timezone MCP Server by RoxyAPI

List all countries - ISO codes and city coverage

get_location_countries

Read-only

Returns every country with ISO 3166-1 alpha-2 and alpha-3 codes, plus the number of searchable cities per country. Use this endpoint to build country dropdown menus, regional filters, or to check city coverage before querying a birth location. Countries are sorted alphabetically by name. Covers Europe, Americas, Asia, Middle East, Africa, and Oceania.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Maximum items to return per page. Range: 1-250, default 50.
`offset`	No	Number of items to skip for pagination. Default 0.
`compact`	No	Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.

Output Schema

TDQS

A3.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the read-only safety profile is covered. The description usefully adds that results are sorted alphabetically, the geographic scope, and the city-count field. However, the claim 'Returns every country' is not tempered by the pagination parameters (limit/offset default 50), leaving how the full list is retrieved unclear.

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?

Four tight sentences front-load the purpose, state concrete use cases, and add sorting and coverage without filler. Every sentence contributes information an agent needs.

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?

With a rich output schema, annotations, and a 100%-described parameter schema, the description does not need to restate return fields. It covers purpose, use cases, and ordering; a minor gap is not signaling how pagination interacts with the 'every country' claim.

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%: limit, offset, and compact each have clear descriptions. The tool description adds no parameter-level semantics beyond implying whole-list retrieval, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description opens with a specific verb and resource: 'Returns every country with ISO 3166-1 alpha-2 and alpha-3 codes, plus the number of searchable cities per country.' This clearly identifies the output. It does not explicitly name or contrast the sibling endpoints (get_location_countries_iso2, get_location_search), so it stops short of full sibling differentiation.

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?

Positive use cases are explicit: 'build country dropdown menus, regional filters, or to check city coverage before querying a birth location.' No when-not-to-use or alternative routing to siblings is provided, so it lacks the exclusionary guidance required for a 5.

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