Query the source-derived codebase graph: files, symbols, imports, calls, routes, tests, package scripts. This is generated from code, not learned memory.
AI agents call kage_code_graph 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.
This tool queries a code graph derived from static analysis of the codebase. It retrieves metadata about code structure (symbols, imports, calls, routes, tests) without modifying code, memory, or external systems. No state changes, deletions, or external operations occur.
From the tool's definition Tool description states 'Query the source-derived codebase graph' — a query operation that retrieves code structure data (files, symbols, imports, calls, routes, tests, package scripts).
Documented attack patterns abuse exactly the kind of access kage_code_graph 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_code_graph:
{
"version": "1",
"default": "deny",
"tools": {
"kage_code_graph": {}
}
}kage_code_graph is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Query the source-derived codebase graph: files, symbols, imports, calls, routes, tests, package scripts. This is generated from code, not learned memory. 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_code_graph: 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_code_graph 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_code_graph 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_code_graph. 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_code_graph 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.
