# Schemas and Adapters

> Understand how Redop turns one input schema into both runtime parsing and MCP discovery metadata.

Redop uses one `input` definition for two jobs:

* runtime parsing
* JSON Schema generation for tool discovery

## The default path

Zod is the smoothest path for new TypeScript projects because it gives you runtime validation and inferred handler types in one place.

## Other supported paths

* Standard Schema-compatible libraries
* plain JSON Schema objects
* custom adapters

## Practical rule

Use the simplest schema system your app already understands well. Redop is flexible, but your team will move fastest when one schema style becomes the default.
