tiger-cli

Overview

Tiger CLI is a comprehensive command-line interface for managing Tiger Cloud database services. It includes an MCP server that exposes tools for service management (list, create, start, stop, resize) and database operations (execute queries) to AI assistants. The CLI supports multiple installation methods and provides authentication, configuration management, and integration with various AI clients. It also proxies tools from a documentation MCP server for semantic search capabilities.
