CLI Wrapper FAQs

Question 1

How do I configure CLI Wrapper for my specific command-line tool?

Accepted Answer

You create a JSON configuration file where you define each subcommand as an MCP tool, specifying its name, description, CLI subcommand string, and type-safe parameters including flags, positional arguments, and boolean switches.

Question 2

Is CLI Wrapper secure against command injection?

Accepted Answer

Yes, it prioritizes security by using `spawnSync` to pass arguments directly to the CLI tool, preventing shell interpolation and command injection vulnerabilities. All inputs are also validated with Zod schemas.

Question 3

Can it handle complex or nested CLI commands?

Accepted Answer

Yes, CLI Wrapper fully supports nested subcommands (e.g., `git remote add`) by allowing you to define them with spaces in the 'subcommand' field within your configuration.

Question 4

How does CLI Wrapper ensure type-safety for CLI tools?

Accepted Answer

It uses Zod for robust parameter validation. You define expected input types (string, number, boolean) in a JSON configuration, ensuring all arguments are correctly typed and validated before execution, preventing errors.

Question 5

What is CLI Wrapper?

Accepted Answer

CLI Wrapper is a flexible MCP (Model Context Protocol) server that converts any command-line interface tool's subcommands into individual, type-safe MCP tools, making them easily accessible and usable by AI agents.
