Why jfrog_update_permission_target needs a policy

This tool modifies permission/access control settings in JFrog, which affects who can access repositories and artifacts. While reversible (Write, not Destructive), misuse could grant unauthorized access to sensitive packages or restrict legitimate users. The high severity reflects the security-critical nature of permission changes in an artifact repository system.

From the tool's definition Tool name explicitly states 'update' and description says 'Update an existing permission target' — a reversible modification of access control configuration in the JFrog platform.

POLICY

How to control jfrog_update_permission_target

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

policy.json

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

jfrog_update_permission_target 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 JFrog MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
