# SveltyCMS — AI Agent Guide > SveltyCMS is a high-performance, database-agnostic headless CMS built with SvelteKit 2, Svelte 5 (Runes), TypeScript, and Tailwind CSS v4. It features automated multi-database adapter layers, runtime cryptographic audit logging, compile-time ParaglideJS localization, and automated workflows. ## Core Documentation - [Architecture](https://docs.sveltycms.com/reference/architecture/): Unified server state machine hooks (IDLE → READY | DEGRADED), event-bus routing, and zero-tax static builds. - [API Reference](https://docs.sveltycms.com/reference/api/): In-depth mechanics for automated REST route dispatchers and authorization middleware context scaling. - [Security Boundaries](https://docs.sveltycms.com/reference/security/): High-fidelity 4-layer defense configurations, SHA-256 tamper-evident audit logging chains, and scoped keys. - [Database Adapters](https://docs.sveltycms.com/reference/database/): Technical interface definitions for production-ready SQLite (WAL), MongoDB, MariaDB, and PostgreSQL engines. - [3-Pillar Component UI](https://docs.sveltycms.com/reference/components/): Lazy-loaded interface field widget loader registries (Definition, Input, Display architecture). ## API Endpoints - [REST Content Dispatcher](https://docs.sveltycms.com/reference/api/collections.mdx): Complete endpoint reference for collections metadata filtering, cursor pagination, and multi-tenant isolation. - [GraphQL API Performance](https://docs.sveltycms.com/reference/api/graphql.mdx): Auto-generated typed GraphQL schemas, query execution blocks, and integrated interactive playground paths. - [Dynamic OpenAPI 3.1 Spec](https://demo.sveltycms.com/api/openapi.json): Machine-readable dynamic schema blueprint updated continuously at runtime. ## Model Context Protocol (MCP) Server - [Hosted MCP Server Hub](https://mcp.sveltycms.com/mcp): Live SSE protocol endpoints exposing active toolkits directly to consumer AI agent systems. - [search_knowledge_base](https://mcp.sveltycms.com/docs/tools#search): Tool for semantic query exploration over the core SveltyCMS configuration and design records. - [read_source_code](https://mcp.sveltycms.com/docs/tools#read): Tool allowing programmatic extraction of runtime source files, database queries, and field hooks. - [get_file_tree](https://mcp.sveltycms.com/docs/tools#tree): Tool providing autonomous visibility into repository file layouts and directory structures. ## Key Repositories & Ecosystem - [SveltyCMS Source](https://github.com/SveltyCMS/SveltyCMS): Core platform engine repository tracking current releases, migration utilities, and test runner matrices. - [Extension Marketplace](https://marketplace.sveltycms.com): Central distribution directory hosting community-vetted widgets, slot extensions, and custom dashboard themes.
