List visible Jenkins queue items.
AI agents call jenkins_list_queue to retrieve information from Jenkins Http without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only operation that lists existing queue items without modifying, executing, or deleting any data. It has minimal blast radius as it only retrieves information about queued builds that the user already has visibility of. No financial, destructive, or execution capabilities are present.
From the tool's definition Tool name 'jenkins_list_queue' and description 'List visible Jenkins queue items' indicate a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
List visible Jenkins queue items. It is categorised as a Read tool in the Jenkins Http MCP Server, which means it retrieves data without modifying state.
Register the Jenkins Http MCP server in PolicyLayer and add a rule for jenkins_list_queue: 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 Http. Nothing to install.
jenkins_list_queue 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 jenkins_list_queue 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 jenkins_list_queue. 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.
jenkins_list_queue is provided by the Jenkins Http MCP server (mdtahmidhossain/jenkins-http-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
