AI agents call getPackageVersions to retrieve information from Azure Devops without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about package versions from an Azure DevOps feed. It performs a read-only operation that queries existing data without side effects, creating, modifying, executing code, or deleting anything. The blast radius of misuse is minimal — an agent could only retrieve information already present in the feed.
From the tool's definition Tool name is 'getPackageVersions' and description states 'Get versions of a package in a feed' — both indicate a query/retrieval operation with no modification or execution of code.
Documented attack patterns abuse exactly the kind of access getPackageVersions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Azure Devops, and nothing reaches the server without passing your rules. This is the rule we recommend for getPackageVersions:
{
"version": "1",
"default": "deny",
"tools": {
"getPackageVersions": {}
}
}getPackageVersions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get versions of a package in a feed. It is categorised as a Read tool in the Azure Devops MCP Server, which means it retrieves data without modifying state.
Register the Azure Devops MCP server in PolicyLayer and add a rule for getPackageVersions: 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 Azure Devops. Nothing to install.
getPackageVersions 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 getPackageVersions 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 getPackageVersions. 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.
getPackageVersions is provided by the Azure Devops MCP server (ryancardin15/azuredevops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
