Examples

Transport Configuration

Server Settings:

  • --address, -a: Server listening address (default: "127.0.0.1")
  • --port, -p: Server listening port (default: 5000)

STDIO:

  • --stdio: Run in MCP STDIO mode instead of HTTP server

Usage Examples

# Basic server with custom port configuration
./toolbox --tools-file "tools.yaml" --port 8080

Tool Configuration Sources

The CLI supports multiple mutually exclusive ways to specify tool configurations:

Single File: (default)

  • --tools-file: Path to a single YAML configuration file (default: tools.yaml)

Multiple Files:

  • --tools-files: Comma-separated list of YAML files to merge

Directory:

  • --tools-folder: Directory containing YAML files to load and merge

Prebuilt Configurations:

  • --prebuilt: Use predefined configurations for specific database types (e.g., 'bigquery', 'postgres', 'spanner'). See Prebuilt Tools Reference for allowed values.

{{< notice tip >}} The CLI enforces mutual exclusivity between configuration source flags, preventing simultaneous use of --prebuilt with file-based options, and ensuring only one of --tools-file, --tools-files, or --tools-folder is used at a time. {{< /notice >}}

Hot Reload

Toolbox enables dynamic reloading by default. To disable, use the --disable-reload flag.

Toolbox UI

To launch Toolbox's interactive UI, use the --ui flag. This allows you to test tools and toolsets with features such as authorized parameters. To learn more, visit Toolbox UI.
