list_geographic_access_countries

Read-only

Retrieve the canonical ISO 3166-1 alpha-2 country catalogue to manage country-based access for tenants in your customer hierarchy. Use this list to configure geographic access policies.

Instructions

Manage country-based access to tenants in your customer hierarchy. Returns the canonical ISO 3166-1 alpha-2 country catalogue used by geographic access policies.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "list_geographic_access_countries"
  }
}

Input Schema

NameRequiredDescriptionDefault
X-Tenant-IdNo
customerContextNoScope the request to a specific customer by ID. Required for DoiT employees (whose token isn't tied to a single customer); omit for direct customer users.

B3.4/5.0
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 safety profile is established. The description adds useful context that the result is a canonical ISO country catalogue, not a per-tenant access list. However, it does not detail auth expectations, tenant scoping behavior, or whether the catalogue is global or varies by context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and mostly efficient, with the key return behavior clearly stated. However, the first sentence 'Manage country-based access to tenants in your customer hierarchy' is generic, somewhat misleading, and does not earn its place next to the sharper second sentence.

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 list operation with read-only annotations and optional parameters, the description provides enough information: the tool returns the canonical ISO 3166-1 alpha-2 country catalogue. The lack of an output schema is partially compensated by the explicit return description, and sibling tool names give surrounding context on geographic-access workflows.

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 50%: customerContext is documented, but X-Tenant-Id is not. The description's mention of 'tenants in your customer hierarchy' loosely connects to the parameters but does not explain how either parameter affects the returned country catalogue. Overall, it adds only domain context rather than specific parameter semantics.

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?

The second sentence clearly states the tool 'Returns the canonical ISO 3166-1 alpha-2 country catalogue used by geographic access policies,' naming a specific verb and resource. However, the first sentence uses 'Manage country-based access,' which implies broader write capabilities and slightly weakens the clarity and differentiation from sibling tools.

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 implies this tool is for retrieving the standard country catalogue relevant to geographic access policies, which gives the agent a clear domain context. It does not explicitly state when to prefer this over sibling tools like custom-region or access-scope tools, nor does it provide exclusions.

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