AI agents call get_all_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 is a read-only operation that retrieves information about Jenkins items without creating, modifying, or deleting anything. However, severity is elevated to 'medium' rather than 'low' because Jenkins inventories typically contain sensitive information (credentials, build secrets, deployment targets, system architecture details).
From the tool's definition Tool name 'get_all_items' and description 'Get all items from Jenkins' indicate data retrieval with no modification. The server context shows this queries Jenkins jobs, builds, nodes, and queues.

Attacks that exploit this kind of access
Get all 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 get_all_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.
get_all_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 get_all_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 get_all_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.
get_all_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.
