Get ASN (Autonomous System Number) information for an IP address
AI agents call get_asn_info_tool to retrieve information from GeoIP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves and returns ASN metadata associated with an IP address. It has no side effects, cannot modify data, execute code, delete information, or move money. The only potential concern is that ASN lookups could be used for reconnaissance in a larger attack chain, but the tool itself is purely informational (Read category).
From the tool's definition Tool retrieves ASN (Autonomous System Number) information for an IP address. Description indicates data retrieval with no modification or deletion capability. The operation is a query/lookup against GeoIP2 databases.
Attacks that exploit this kind of access
Get ASN (Autonomous System Number) information for an IP address. It is categorised as a Read tool in the GeoIP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GeoIP MCP Server MCP server in PolicyLayer and add a rule for get_asn_info_tool: 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 GeoIP MCP Server. Nothing to install.
get_asn_info_tool is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_asn_info_tool 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.
Set action: deny in the PolicyLayer policy for get_asn_info_tool. 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.
get_asn_info_tool is provided by the GeoIP MCP Server MCP server (mamorett/mcp_geoip2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
