pibblokto/cert-manager-mcp-server

Overview

The pibblokto/cert-manager-mcp-server is an MCP (Model Context Protocol) server that connects AI agents to cert-manager on Kubernetes. It enables natural language or tool-based management of TLS certificates, issuers, and related resources. The server is written in Python and provides a bridge between AI assistants and Kubernetes certificate operations.
