AI agents call get_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 is a read-only query operation that retrieves information about a Jenkins item (job, build, or configuration). It has no side effects and cannot modify or delete data. Severity is medium rather than low because unauthorized access to Jenkins item details could reveal sensitive build information, credentials in logs, or infrastructure details, though the tool itself performs no destructive action.
From the tool's definition Tool name 'get_item' and description 'Get specific item from Jenkins' indicate retrieval of data without modification. Sibling tools like 'get_all_items', 'get_build', and 'get_build_console_output' confirm this server's read operations.
Attacks that exploit this kind of access
Get specific item 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 get_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_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_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_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_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.
