AI agents call query_items 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 or queries data from Jenkins without modifying it. It has no side effects and matches the Read category definition. Severity is medium rather than low because Jenkins exposes CI/CD system state (job configurations, build history, credentials context) that could be sensitive in some environments; unauthorized querying could inform adversaries about infrastructure.
From the tool's definition Tool name is 'query_items' and description states 'Query items from Jenkins.' The sibling tools include read-only operations like 'get_all_items', 'get_build', 'get_build_console_output', etc., establishing the pattern of read operations on this server.
Attacks that exploit this kind of access
Query items from Jenkins. 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 query_items: 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.
query_items 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 query_items 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 query_items. 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.
query_items 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.
query_items is one line of Jenkins's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
