Useful for when you need to get a list of versions of a publicly available package.
AI agents call jfrog_get_package_versions to retrieve information from JFrog MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries package version metadata from the JFrog Platform. It performs a read-only lookup operation on publicly available data with no ability to modify, delete, or execute code. The blast radius of misuse is minimal (information disclosure of already-public data). Severity is low because the data is explicitly stated as publicly available.
From the tool's definition Tool retrieves 'a list of versions of a publicly available package' — a query operation with no side effects, pure data retrieval.
Documented attack patterns abuse exactly the kind of access jfrog_get_package_versions gives an agent:
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_versions:
{
"version": "1",
"default": "deny",
"tools": {
"jfrog_get_package_versions": {}
}
}jfrog_get_package_versions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Useful for when you need to get a list of versions of a publicly available package. It is categorised as a Read tool in the JFrog MCP Server MCP Server, which means it retrieves data without modifying state.
Register the JFrog MCP Server MCP server in PolicyLayer and add a rule for jfrog_get_package_versions: 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 JFrog MCP Server. Nothing to install.
jfrog_get_package_versions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the jfrog_get_package_versions 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.
Set action: deny in the PolicyLayer policy for jfrog_get_package_versions. 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.
jfrog_get_package_versions is provided by the JFrog MCP Server MCP server (jfrog/mcp-jfrog). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from JFrog MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
