It lets you create agents that can interact with tools, handle complex workflows, and communicate with users. ### Key features Key features of Koog include: - **Multiplatform development**: Deploy agents across JVM, JS, WasmJS, Android, and iOS targets using Kotlin Multiplatform. - **Reliability and fault-tolerance**: Handle failures with built-in retries and restore the agent state at specific points during execution with the agent persistence feature. - **Intelligent history compression**: Optimize token usage while maintaining context in long-running conversations using advanced built-in history compression techniques. - **Enterprise-ready integrations**: Utilize integration with popular JVM frameworks such as Spring Boot and Ktor to embed Koog into your applications. - **Observability with OpenTelemetry exporters**: Monitor and debug applications with built-in support for popular observability providers (W&B Weave, Langfuse). - **LLM switching and seamless history adaptation**: Switch to a different LLM at any point without losing the existing conversation history, or reroute between multiple LLM providers. - **Integration with JVM and Kotlin applications**: Build AI agents with an idiomatic, type-safe Kotlin DSL designed specifically for JVM and Kotlin developers. - **Model Context Protocol integration**: Use Model Context Protocol (MCP) tools in AI agents. - **Agent Client Protocol integration**: Build ACP-compliant agents that can communicate with standardized client applications using the Agent Client Protocol (ACP). - **Knowledge retrieval and memory**: Retain and retrieve knowledge across conversations using vector embeddings and RAG. - **Powerful Streaming API**: Process responses in real-time with streaming support and parallel tool calls. - **Modular feature system**: Customize agent capabilities through a composable architecture. - **Flexible graph workflows**: Design complex agent behaviors using intuitive graph-based workflows. - **Custom tool creation**: Enhance your agents with tools that access external systems and APIs. - **Comprehensive tracing**: Debug and monitor agent execution with detailed, configurable tracing. ### Available LLM providers and platforms The LLM providers and platforms whose LLMs you can use to power your agent capabilities: - Google - OpenAI - Anthropic - De
