Determine if one or more IP addresses originate from a proxy.
AI agents call is_proxy to retrieve information from Pangea MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs IP intelligence analysis by checking if addresses are associated with proxy services. It is a read-only query operation with no side effects—it retrieves classification data about IP addresses but does not create, modify, delete, or execute anything.
From the tool's definition Tool name 'is_proxy' and description 'Determine if one or more IP addresses originate from a proxy' indicate a query/lookup operation that retrieves information about IP addresses without modifying, deleting, or executing external actions.
Attacks that exploit this kind of access
Determine if one or more IP addresses originate from a proxy. It is categorised as a Read tool in the Pangea MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pangea MCP Server MCP server in PolicyLayer and add a rule for is_proxy: 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 Pangea MCP Server. Nothing to install.
is_proxy 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 is_proxy 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 is_proxy. 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.
is_proxy is provided by the Pangea MCP Server MCP server (pangeacyber/pangea-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
