Why jfrog_promote_release_bundle needs a policy

Release bundle promotion is a write operation that modifies artifact distribution and state within the JFrog platform. While reversible (artifacts can typically be demoted or removed), the operation has significant blast radius in CI/CD pipelines—promoting incorrect or malicious artifacts could push them to production environments, affecting downstream systems and users.

From the tool's definition The tool description states it will "copying or moving its contents" of a release bundle version, which modifies the state and location of artifacts in the JFrog platform.

POLICY

How to control jfrog_promote_release_bundle

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_promote_release_bundle:

policy.json

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

jfrog_promote_release_bundle 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.
