AI agents call get_queue_item to retrieve information from Jenkins without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a queued Jenkins job by its ID. It performs a read-only query with no side effects—it does not create, modify, delete, or execute anything. While Jenkins controls critical CI/CD infrastructure, this specific tool only queries queue state, making it a Read classification. Severity is low because retrieving queue metadata poses minimal risk of misuse.
From the tool's definition Tool name 'get_queue_item' and description 'Get a specific item in Jenkins queue by id' indicate a retrieval operation with no modification.
Attacks that exploit this kind of access
Get a specific item in Jenkins queue by id. It is categorised as a Read tool in the Jenkins MCP Server, which means it retrieves data without modifying state.
Register the Jenkins MCP server in PolicyLayer and add a rule for get_queue_item: 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 Jenkins. Nothing to install.
get_queue_item 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 get_queue_item 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 get_queue_item. 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.
get_queue_item is provided by the Jenkins MCP server (mcpland/jenkins-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
