semaphore
Modern UI and powerful API for Ansible, Terraform/OpenTofu/Terragrunt, PowerShell and other DevOps tools.
The Semaphore MCP server enables AI assistants to interact with Semaphore UI, a web-based DevOps automation platform for managing Ansible, Terraform, OpenTofu, Terragrunt, and PowerShell deployments. By integrating this MCP server, AI agents gain programmatic access to execute playbooks, run infrastructure-as-code templates, manage task schedules, and control deployment workflows through Semaphore's API. This building block bridges conversational AI with production DevOps orchestration, allowing assistants to trigger and monitor infrastructure tasks on behalf of users.
Key Features
