Get information about a specific build or the last build
AI agents call getBuild to retrieve information from Jenkins MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries build information from Jenkins without side effects. It does not trigger builds, modify build state, delete data, or execute operations. It is a straightforward data retrieval operation, making it a Read category tool with low severity.
From the tool's definition Tool name 'getBuild' and description 'Get information about a specific build or the last build' indicate retrieval of build metadata without modification or execution.
Attacks that exploit this kind of access
Get information about a specific build or the last build. It is categorised as a Read tool in the Jenkins MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jenkins MCP Server MCP server in PolicyLayer and add a rule for getBuild: 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 MCP Server. Nothing to install.
getBuild 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 getBuild 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 getBuild. 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.
getBuild is provided by the Jenkins MCP Server MCP server (umishra1504/jenkins-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
