# Catalyst

The Catalyst API lets you deploy and manage Dapr and its building blocks across Diagrid Cloud, including projects, app identities, Pub/Sub components, key-value stores, subscriptions, configurations, resiliency policies, HTTP endpoints, MCP servers, and agents. Requests and responses follow JSON:API conventions, and most write operations are processed asynchronously.
