WHAT IT DOES

What codexray_overview does on CodeXRay

AI agents call codexray_overview 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.

THE RISK

Low Risk

Why codexray_overview needs a policy

codexray_overview performs static analysis and returns informational summaries about code structure without side effects. It queries a pre-built semantic knowledge graph (read-only lookup). No data is created, modified, deleted, or executed. The blast radius of misuse is minimal—worst case an AI agent wastes context tokens on irrelevant overview data.

From the tool's definition Tool description states it 'Get[s] a high-level project overview' of metrics like file count, languages, symbol distribution, and directory structure. These are retrieval-only operations with no modification, creation, deletion, or execution capability.

POLICY

How to control codexray_overview

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_overview:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "codexray_overview": {}
  }
}

codexray_overview is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register CodeXRay — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about codexray_overview

What does the codexray_overview tool do? +

Get a high-level project overview including file count, languages, symbol distribution, key hotspot symbols, and directory structure. Use this FIRST when starting work on an unfamiliar project. It is categorised as a Read tool in the CodeXRay MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on codexray_overview? +

Register the CodeXRay MCP server in PolicyLayer and add a rule for codexray_overview: 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.

What risk level is codexray_overview? +

codexray_overview is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit codexray_overview? +

Yes. Add a rate_limit block to the codexray_overview 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.

How do I block codexray_overview completely? +

Set action: deny in the PolicyLayer policy for codexray_overview. 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.

What MCP server provides codexray_overview? +

codexray_overview 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.

Enforce policy on every CodeXRay tool call.

Start from CodeXRay, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
