THE RISK

Medium Risk

Why kage_review_artifact needs a policy

The tool creates (writes) a new artifact—a Markdown document—summarizing pending memory packets. This is a reversible write operation (the artifact can be edited, deleted, or regenerated). It does not execute arbitrary code, delete data irreversibly, move money, or perform Read-only queries.

From the tool's definition Tool 'creates' a Markdown review artifact, which is explicitly a write operation that generates and stores a new artifact for PR/human review.

POLICY

How to control kage_review_artifact

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "kage_review_artifact": {
      "limits": [
        {
          "counter": "kage_review_artifact_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

kage_review_artifact stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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