Multiple installation methods are provided. Choose your preferred method from the options below. If you aren't sure, use the first one!

Tiger CLI provides the following commands:
tiger auth - Authentication management

Tiger CLI includes a Model Context Protocol (MCP) server that enables AI assistants like Claude Code to interact with your Tiger Cloud infrastructure. The MCP server provides programmatic access to database services and operations.
Configure the MCP server for your AI assistant:
# Interactive installation (prompts for client selection)
tiger mcp install
# Or specify your client directly
tiger mcp install claude-code # Claude Code
tiger mcp install codex # Codex
tiger mcp install cursor # Cursor IDE
tiger mcp install gemini # Gemini CLI
tiger mcp install vscode # VS Code
tiger mcp install windsurf # Windsurf
After installation, restart your AI assistant to activate the Tiger MCP server.
If your MCP client is not supported by tiger mcp install, follow the client's
instructions for installing MCP servers. Use tiger mcp start as the command to
start the MCP server. For example, many clients use a JSON file like the
following:
{
"mcpServers": {
"tiger": {
"command": "tiger",
"args": [
"mcp",
"start"
]
}
}
}
The above instructions install the MCP server using the stdio transport. If you
need to use the Streamable HTTP transport instead, you can start the server with
tiger mcp start http --port 8080 and install it into your client using
http://localhost:8080 as the URL.
The MCP server exposes the following tools to AI assistants:
Service Management:
service_list - List all database services in your projectservice_get - Get detailed information about a specific serviceservice_create - Create new database services with configurable resourcesservice_fork - Fork an existing database service to create an independent copyservice_start - Start a stopped database serviceservice_stop - Stop a running database serviceservice_resize - Resize a database service by changing CPU and memory allocationservice_update_password - Update the master password for a serviceservice_logs - View logs for a database serviceDatabase Operations:
db_execute_query - Execute SQL queries against a database service with support for parameterized queries, custom timeouts, and connection poolingThe MCP server automatically uses your CLI authentication and configuration, so no additional setup is required beyond tiger auth login.
In addition to the service management tools listed above, the Tiger MCP server also proxies tools from a remote documentation MCP server. This feature provides AI assistants with semantic search capabilities for PostgreSQL, TimescaleDB, and Tiger Cloud documentation, as well as prompts/guides for various Tiger Cloud features.
The proxied documentation server (pg-aiguide) currently provides the following tools:
view_skill - Retrieve comprehensive guides for Postgres and TimescaleDB features and best practicessearch_docs - Search PostgreSQL and TimescaleDB documentation using natural language queriesThis proxy connection is enabled by default and requires no additional configuration.
To disable the documentation proxy:
tiger config set docs_mcp false
The CLI stores configuration in ~/.config/tiger/config.yaml by default, and supports hierarchical configuration through environment variables and command-line flags.
# Show current configuration
tiger config show
# Set configuration values
tiger config set output json
# Remove configuration value
tiger config unset output
# Reset to defaults
tiger config reset
All configuration options can be set via tiger config set <key> <value>:
