get_build_artifact
AI agents call get_build_artifact 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.
The tool name strongly suggests artifact retrieval/fetching, which is a read operation. The description is empty, reducing confidence slightly, but the naming convention and sibling tools confirm this is a query operation that retrieves existing artifact data without modification or execution.
From the tool's definition Tool name 'get_build_artifact' indicates retrieval of build artifacts; no destructive or side-effect language present. Consistent with sibling tool 'get_all_build_artifacts' and 'get_build_artifact_url' which are clearly read-only retrieval functions.
Attacks that exploit this kind of access
get_build_artifact. 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_build_artifact: 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_build_artifact 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_build_artifact 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_build_artifact. 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_build_artifact 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.
