AgentBack - AI native API/MCP framework

AgentBack simplifies building HTTP APIs and MCP servers from a single codebase. Key features include: • Unified Zod schema for validation and documentation • Automatic OpenAPI 3.1 specification generation • MCP tool creation from shared schemas • Codegen-free typed client generation • Dependency injection container for consistent contracts This framework, a specialized fork of LoopBack 4, revolutionizes how backends are developed and consumed. By defining a Zod schema just once on a decorator, it becomes the definitive source for request validation, a comprehensive OpenAPI 3.1 specification, the foundation for MCP tools, and a typed client without any additional code generation. This approach ensures maximal consistency and efficiency across all integration points. AgentBack is ideal for development teams creating robust APIs that need to serve both traditional applications and specialized digital agents. It ensures that the runtime contract, service contract, and agent contract are all derived from a single, authoritative source, eliminating inconsistencies and reducing development overhead. This "schema-first" paradigm makes best practices the easiest path to follow, streamlining development and ensuring all interfaces are perfectly aligned and easily consumable.
