Read the artifact gate failure that must be repaired.
AI agents call read_gate_error to retrieve information from Ktx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries information about a gate failure artifact without creating, modifying, deleting, or executing any operations. It has no side effects beyond returning data to the requester.
From the tool's definition Tool name 'read_gate_error' and description 'Read the artifact gate failure that must be repaired' indicate data retrieval only. The verb 'read' and lack of any modification, deletion, or execution language confirm this is a read operation.
Documented attack patterns abuse exactly the kind of access read_gate_error gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ktx, and nothing reaches the server without passing your rules. This is the rule we recommend for read_gate_error:
{
"version": "1",
"default": "deny",
"tools": {
"read_gate_error": {}
}
}read_gate_error is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read the artifact gate failure that must be repaired. It is categorised as a Read tool in the Ktx MCP Server, which means it retrieves data without modifying state.
Register the Ktx MCP server in PolicyLayer and add a rule for read_gate_error: 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 Ktx. Nothing to install.
read_gate_error 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 read_gate_error 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 read_gate_error. 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.
read_gate_error is provided by the Ktx MCP server (kaelio/ktx). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ktx, 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.
