Return a 5G Core topology view with NFs, SBI endpoints, PLMN and slices.
AI agents call tool_fiveg_core_topology to retrieve information from Kubernetes MCP Server – 5G Core Edition without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only querying of Kubernetes and 5G Core topology state. It retrieves and presents information about network functions, service-based interfaces, PLMN identifiers, and network slices. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an AI agent with this tool can only observe cluster topology, not alter it.
From the tool's definition Tool description states it 'Return[s] a 5G Core topology view' — a retrieval operation that queries and displays cluster state (network functions, endpoints, slices) without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Return a 5G Core topology view with NFs, SBI endpoints, PLMN and slices. It is categorised as a Read tool in the Kubernetes MCP Server – 5G Core Edition MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server – 5G Core Edition MCP server in PolicyLayer and add a rule for tool_fiveg_core_topology: 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 Kubernetes MCP Server – 5G Core Edition. Nothing to install.
tool_fiveg_core_topology 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 tool_fiveg_core_topology 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 tool_fiveg_core_topology. 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.
tool_fiveg_core_topology is provided by the Kubernetes MCP Server – 5G Core Edition MCP server (sanzco/mcp5g). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
