AI agents invoke codegraph_traverse_graph to trigger processes or run actions in Codegraph. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
codegraph_traverse_graph can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access codegraph_traverse_graph gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Advanced graph traversal for complex code exploration. USE WHEN: specialized analysis requiring custom traversal (not covered by get_callers/get_callees/get_dependency_graph). PREFER simpler tools for common cases. Returns nodes and edges discovered during traversal. edgeTypes filters which relationships to follow (e.g., ['calls', 'imports']). nodeTypes filters which node kinds appear in results. Identify start node via uri+line or startNodeId from symbol_search.. It is categorised as a Execute tool in the Codegraph MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Codegraph MCP server in PolicyLayer and add a rule for codegraph_traverse_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 Codegraph. Nothing to install.
codegraph_traverse_graph is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the codegraph_traverse_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 codegraph_traverse_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.
codegraph_traverse_graph is provided by the Codegraph MCP server (codegraph-ai/CodeGraph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
