Return a first-use Repo X-Ray: code structure layers for entry points, core files, risk, tests, memory overlay, and knowledge gaps.
AI agents call kage_xray to retrieve information from Kage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and analyzes repository structure—entry points, core files, risk areas, tests, and memory overlay—returning a structured report. There is no indication it modifies, executes, or deletes anything; it is purely a read/query operation producing an informational overview of the codebase.
From the tool's definition Return a first-use Repo X-Ray: code structure layers for entry points, core files, risk, tests, memory overlay, and knowledge gaps.
Documented attack patterns abuse exactly the kind of access kage_xray gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kage, and nothing reaches the server without passing your rules. This is the rule we recommend for kage_xray:
{
"version": "1",
"default": "deny",
"tools": {
"kage_xray": {}
}
}kage_xray is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return a first-use Repo X-Ray: code structure layers for entry points, core files, risk, tests, memory overlay, and knowledge gaps. It is categorised as a Read tool in the Kage MCP Server, which means it retrieves data without modifying state.
Register the Kage MCP server in PolicyLayer and add a rule for kage_xray: 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 Kage. Nothing to install.
kage_xray 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 kage_xray 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 kage_xray. 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.
kage_xray is provided by the Kage MCP server (@kage-core/kage-graph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kage, 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.
