fiveg_health_check
AI agents call fiveg_health_check 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.
Health checks retrieve cluster or network function state without modifying data or triggering external operations. Despite the empty description reducing confidence slightly, the tool name and context (sibling read-only Kubernetes and 5G status tools) strongly indicate a read-only query operation. No evidence of side effects, data mutation, or destructive capability.
From the tool's definition Tool name 'fiveg_health_check' suggests health/status inspection of 5G core components, consistent with sibling tools like 'fiveg_nf_status' and 'fiveg_core_topology' which are read-only introspection utilities.
Attacks that exploit this kind of access
fiveg_health_check. 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 fiveg_health_check: 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.
fiveg_health_check 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 fiveg_health_check 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 fiveg_health_check. 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.
fiveg_health_check 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.
