Get one Jenkins computer/node by name. Use (built-in) for the built-in node.
AI agents call jenkins_get_node 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.

Register the Jenkins Http MCP server in PolicyLayer and add a rule for jenkins_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 Jenkins Http. Nothing to install.
jenkins_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 jenkins_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 jenkins_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.
jenkins_get_node 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.
