Zero FAQs

Question 1

What are the core requirements for using Zero MCP Kotlin?

Accepted Answer

To use Zero, you need Kotlin 2.0+ (or newer), a JVM 21 environment, and Gradle for project management. These ensure compatibility and optimal performance for your MCP tool development.

Question 2

What is Zero MCP Kotlin?

Accepted Answer

Zero is a high-performance, sandboxed server library for Kotlin, designed to simplify building and serving tools compatible with the MCP protocol. It provides a clean Kotlin DSL for tool registration and handles the underlying protocol complexities automatically.

Question 3

How does Zero compare to the official Kotlin MCP SDK?

Accepted Answer

Zero significantly outperforms the official SDK, handling requests up to 8.4x faster. It also provides robust per-tool sandboxing (network allowlists, filesystem controls, exec prevention), which the official SDK lacks, and simplifies setup with automatic protocol and schema generation.

Question 4

Can Zero integrate with existing HTTP frameworks?

Accepted Answer

Yes, Zero is designed for flexible integration. It doesn't own the HTTP layer; instead, it provides a suspendable `handleRequest` method that allows you to bring your own HTTP framework (like Ktor, Spring WebFlux, etc.) and seamlessly integrate it.

Question 5

What kind of sandboxing features does Zero offer?

Accepted Answer

Zero provides comprehensive per-tool sandboxing, including network allowlists to restrict outbound connections, filesystem controls (read/write permissions), and prevention of arbitrary execution, ensuring your tools run in a secure, isolated environment.
