get_country

Get country information by name or ISO code (e.g., 'US', 'FR'). Returns capital, population, currency, languages, and neighboring countries. Use for regional context or facts.

Part of the Geo server.

get_country is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call get_country to retrieve information from Geo without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though get_country only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so get_country only ever does what you allow.

What does the get_country tool do? +

Get country information by name or ISO code (e.g., 'US', 'FR'). Returns capital, population, currency, languages, and neighboring countries. Use for regional context or facts.. It is categorised as a Read tool in the Geo MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_country? +

Register the Geo MCP server in PolicyLayer and add a rule for get_country: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Geo. Nothing to install.

What risk level is get_country? +

get_country is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_country? +

Yes. Add a rate_limit block to the get_country rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block get_country completely? +

Set action: deny in the PolicyLayer policy for get_country. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides get_country? +

get_country is provided by the Geo MCP server (https://gateway.pipeworx.io/geo/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Geo tool call.
