Get a specific node from Jenkins
AI agents call get_node to retrieve information from Mcp 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 Jenkins node (an agent/machine in the Jenkins infrastructure). It queries existing data without side effects, making it a Read operation. The severity is low because node metadata retrieval poses minimal risk—an agent might learn about infrastructure topology, but this is reconnaissance-level impact rather than operational risk.
From the tool's definition Tool name 'get_node' and description 'Get a specific node from Jenkins' indicate a retrieval operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Get a specific node from Jenkins. It is categorised as a Read tool in the Mcp Jenkins MCP Server, which means it retrieves data without modifying state.
Register the Mcp Jenkins MCP server in PolicyLayer and add a rule for get_node: 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 Mcp Jenkins. Nothing to install.
get_node 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_node 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_node. 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_node is provided by the Mcp Jenkins MCP server (lanbaoshen/mcp-jenkins). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
