## What it is
SchemaStore is a large open-source catalog of JSON schemas for popular configuration and data file formats, served via a public API and website. Editors and tools consume it to provide validation, auto-completion, and in-context documentation for JSON, YAML, and TOML files.

## Use cases
- get  schema autocomplete for config files in vscode
- validate package. or tsconfig. against a schema
- find a  schema for a known file format
- integrate schema validation into a cli validator
- let an ai assistant fetch  schemas via mcp

## When to choose
- your editor or tool needs schema-based completion and validation for common /yaml/toml files
- you need a central, community-maintained schema catalog with a public api
- you want to contribute a schema for a widely used file format

## When to avoid
- you need schemas for proprietary or niche internal formats not in the catalog
- you need a runtime schema registry for your own microservices rather than a public catalog
- you need non-schema validation logic beyond  schema

## Facets
