travis_restartBuild · Mcp Travis MCP: Risk & Policy

WHAT IT DOES

What travis_restartBuild does on Mcp Travis

AI agents invoke travis_restartBuild to trigger actions in Mcp Travis. 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 travis_restartBuild needs a policy

This tool executes an external operation (build restart) in the Travis CI system. While not destructive (the build itself isn't deleted) and not financial, it performs a significant operational action that could have wide-ranging effects on CI/CD pipelines, resource consumption, and deployment workflows.

From the tool's definition 'Restart a build by buildId' - restarts a build, which triggers external CI/CD operations whose effects depend on the buildId argument provided. Rebuilding can consume compute resources, trigger downstream deployments, and affect build queues.
