get_stats

THE RISK

Low Risk

Why get_stats needs a policy

This tool queries and retrieves analytical data about the code graph structure without creating, modifying, deleting, or executing anything. It is a pure read operation that gathers statistics for inspection purposes. No side effects or irreversible actions are possible. Low severity because misuse would only expose metadata statistics about the codebase, not sensitive code content itself.

From the tool's definition Tool retrieves graph-wide statistics including 'node/edge counts by type, largest files, most connected entities' with no modification capability described.

POLICY

How to control get_stats

PolicyLayer is an MCP gateway — it sits between your AI agents and CodeGraph, and nothing reaches the server without passing your rules. This is the rule we recommend for get_stats:

policy.json

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

get_stats 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 CodeGraph — 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 get_stats

What does the get_stats tool do? +

Get graph-wide statistics: node/edge counts by type, largest files, most connected entities. It is categorised as a Read tool in the CodeGraph MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_stats? +

Register the CodeGraph MCP server in PolicyLayer and add a rule for get_stats: 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.

What risk level is get_stats? +

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

Can I rate-limit get_stats? +

Yes. Add a rate_limit block to the get_stats 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 get_stats completely? +

Set action: deny in the PolicyLayer policy for get_stats. 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 get_stats? +

get_stats is provided by the CodeGraph MCP server (phoenixrr2113/codebase-graph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every CodeGraph tool call.

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