Why jfrog_get_package_version_vulnerabilities needs a policy

The tool retrieves security vulnerability information about package versions, which is fundamentally a query/lookup operation. It has no side effects on repositories, artifacts, permissions, or any system state. The 'package security analysis' capability mentioned in the server description is satisfied by this read-only query function. No data is created, modified, deleted, or executed.

From the tool's definition Tool queries and retrieves 'list of known vulnerabilities affecting a specific version of an open source package' — this is a read-only data retrieval operation with no modification, deletion, or execution of code.

How to control jfrog_get_package_version_vulnerabilities

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_get_package_version_vulnerabilities:

policy.json

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

jfrog_get_package_version_vulnerabilities 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 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.
