THE RISK

Low Risk

Why inventory_traces needs a policy

This tool retrieves and displays metadata about stored traces without altering, deleting, or executing anything. However, the 'medium' severity reflects that an AI agent with access to this inventory could discover sensitive trace locations and potentially reference them for exfiltration or further reconnaissance, especially given the sensitivity categorization.

From the tool's definition Tool name and description indicate 'Show complete inventory' of stored traces—this is a query/list operation with no modification, deletion, or execution. The description explicitly frames this as showing/displaying information ('Show complete inventory').

POLICY

How to control inventory_traces

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

policy.json

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

inventory_traces 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 Claude Code Toolkit — 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 inventory_traces

What does the inventory_traces tool do? +

Show complete inventory of all traces Claude Code has stored on disk, categorized by sensitivity level (critical/high/medium/low). It is categorised as a Read tool in the Claude Code Toolkit MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on inventory_traces? +

Register the Claude Code Toolkit MCP server in PolicyLayer and add a rule for inventory_traces: 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 Claude Code Toolkit. Nothing to install.

What risk level is inventory_traces? +

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

Can I rate-limit inventory_traces? +

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

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

inventory_traces is provided by the Claude Code Toolkit MCP server (asifkibria/claude-code-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Claude Code Toolkit tool call.

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