WHAT IT DOES

What jenkins_trigger_build_with_parameters does on Jenkins Http

AI agents invoke jenkins_trigger_build_with_parameters to trigger actions in Jenkins Http. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why jenkins_trigger_build_with_parameters needs a policy

This tool triggers external CI/CD operations (Jenkins builds) whose side effects are determined by the job definition and parameters provided. While not inherently destructive, the execution of arbitrary build tasks (which may compile, test, deploy, or run scripts) makes this an Execute risk.

From the tool's definition Tool name 'jenkins_trigger_build_with_parameters' and description 'Trigger a parameterized job build' indicate execution of arbitrary build jobs. Jenkins builds execute code/scripts whose effects depend on job configuration and parameters (arguments).

FAQ

Questions about jenkins_trigger_build_with_parameters

What does the jenkins_trigger_build_with_parameters tool do? +

Trigger a parameterized job build. Requires JENKINS_MCP_ENABLE_WRITES=1. It is categorised as a Execute tool in the Jenkins Http MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on jenkins_trigger_build_with_parameters? +

Register the Jenkins Http MCP server in PolicyLayer and add a rule for jenkins_trigger_build_with_parameters: 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.

What risk level is jenkins_trigger_build_with_parameters? +

jenkins_trigger_build_with_parameters is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit jenkins_trigger_build_with_parameters? +

Yes. Add a rate_limit block to the jenkins_trigger_build_with_parameters 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.

How do I block jenkins_trigger_build_with_parameters completely? +

Set action: deny in the PolicyLayer policy for jenkins_trigger_build_with_parameters. 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.

What MCP server provides jenkins_trigger_build_with_parameters? +

jenkins_trigger_build_with_parameters 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.
