Find all functions/methods that CALL the specified symbol. Essential for understanding usage patterns and impact before making changes.
AI agents call codexray_callers to retrieve information from CodeXRay without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
codexray_callers performs a read-only analysis of a semantic knowledge graph to identify callers of a given symbol. It has no side effects, does not execute code, does not modify or delete data, and does not involve financial operations. The tool is used for exploration and understanding of code structure, fitting squarely into the Read category.
From the tool's definition Tool description states it 'Find all functions/methods that CALL the specified symbol' — a query operation that retrieves data about code relationships without modifying, executing, or deleting anything.
Documented attack patterns abuse exactly the kind of access codexray_callers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CodeXRay, and nothing reaches the server without passing your rules. This is the rule we recommend for codexray_callers:
{
"version": "1",
"default": "deny",
"tools": {
"codexray_callers": {}
}
}codexray_callers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find all functions/methods that CALL the specified symbol. Essential for understanding usage patterns and impact before making changes. It is categorised as a Read tool in the CodeXRay MCP Server, which means it retrieves data without modifying state.
Register the CodeXRay MCP server in PolicyLayer and add a rule for codexray_callers: 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 CodeXRay. Nothing to install.
codexray_callers 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 codexray_callers 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 codexray_callers. 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.
codexray_callers is provided by the CodeXRay MCP server (neuralrays/codexray). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CodeXRay, 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.
