Get a label's key ID by label ID. This is used to get the key ID needed for tag filtering operations.
AI agents call get_label_key_id to retrieve information from Kion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (a label's key ID) to support filtering operations. It performs a lookup query without modifying, deleting, or executing any operations. The returned ID is used downstream by other tools, but this tool itself only reads and returns data, making it a Read-category tool with low severity.
From the tool's definition The tool description explicitly states it 'Get[s] a label's key ID by label ID' — a pure data retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_label_key_id gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kion MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_label_key_id:
{
"version": "1",
"default": "deny",
"tools": {
"get_label_key_id": {}
}
}get_label_key_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a label's key ID by label ID. This is used to get the key ID needed for tag filtering operations. It is categorised as a Read tool in the Kion MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kion MCP Server MCP server in PolicyLayer and add a rule for get_label_key_id: 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 Kion MCP Server. Nothing to install.
get_label_key_id 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_label_key_id 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_label_key_id. 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_label_key_id is provided by the Kion MCP Server MCP server (kionsoftware/kion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kion MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
