# Echo

> Use this tool when you need to validate and structure messages for AI agents, solving problems of data inconsistency and validation errors. Echo enables the emission of schema-validated messages through tool call returns, taking in JSON payloads and schema definitions as inputs and outputting validated messages. It is ideal for use cases requiring robust data validation and schema discovery, such as data integration and messaging workflows.

## Description

It exposes three tools — list_schemas, get_schema, and echo — for discovering schemas, retrieving their definitions, and validating payloads using JSON Schema and Zod validation.
