Get consoleText for a build, truncated by JENKINS_MCP_MAX_LOG_BYTES.
AI agents call jenkins_get_build_log 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.
This tool queries and retrieves build log data (consoleText) from an existing build. It is a read-only operation with no side effects, data modification, code execution, or destructive capability. The truncation by JENKINS_MCP_MAX_LOG_BYTES is a safety limit on output size, not a write or execute action. Misuse would expose log contents but cannot alter Jenkins state or trigger operations.
From the tool's definition Tool description states 'Get consoleText for a build' — retrieves build log output without modification. No parameters suggest altering state or triggering actions.
Attacks that exploit this kind of access
Get consoleText for a build, truncated by JENKINS_MCP_MAX_LOG_BYTES. It is categorised as a Read tool in the Jenkins Http MCP Server, which means it retrieves data without modifying state.
Register the Jenkins Http MCP server in PolicyLayer and add a rule for jenkins_get_build_log: 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_build_log 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_build_log 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_build_log. 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_build_log 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.
