Lite FAQs

Question 1

Does Lite support serverless and distributed environments?

Accepted Answer

Yes, Lite's Fetch API-based transport is compatible with various environments like Node, Bun, Cloudflare Workers, and Deno. It uses opt-in adapter interfaces for sessions and client requests, allowing seamless scaling from stateless local prototyping to distributed deployments with shared storage (e.g., Redis, KV).

Question 2

What are the key features of Lite?

Accepted Answer

Lite boasts zero runtime dependencies, type-safe tool definitions with standard schemas (e.g., Zod, Valibot), structured outputs with runtime validation, HTTP + SSE transport built on the Fetch API, and flexible adapter interfaces for sessions and persistence.

Question 3

What is Lite?

Accepted Answer

Lite is a minimal, composable TypeScript framework designed for quickly building Model Context Protocol (MCP) servers. It offers type-safe tool definitions and a fetch-first HTTP + SSE transport.

Question 4

What is the Model Context Protocol (MCP)?

Accepted Answer

The Model Context Protocol (MCP) is an open standard that enables secure connections between host applications and external data sources or tools, allowing AI assistants to reason over information and execute functions with user permission.

Question 5

How does Lite ensure type safety in tool definitions?

Accepted Answer

Lite provides type-safe tool definitions by integrating with Standard Schema validators (like Zod, Valibot, Effect). This enables automatic type inference for tool input arguments and structured outputs, ensuring strong type checking both at compile time and with runtime validation.
