# NVIDIA NeMo Agent Toolkit

NeMo Agent Toolkit is a flexible library designed to seamlessly integrate your enterprise agents—regardless of framework—with various data sources and tools. By treating agents, tools, and agentic workflows as simple function calls, NeMo Agent Toolkit enables true composability: build once and reuse anywhere.

## Key Features

- [**Framework Agnostic:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/extend/plugins.html) Works with any agentic framework, so you can use your current technology stack without replatforming.
- [**Reusability:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/extend/sharing-components.html) Every agent, tool, or workflow can be combined and repurposed, allowing developers to leverage existing work in new scenarios.
- [**Rapid Development:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/tutorials/index.html) Start with a pre-built agent, tool, or workflow, and customize it to your needs.
- [**Profiling:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/profiler.html) Profile entire workflows down to the tool and agent level, track input/output tokens and timings, and identify bottlenecks.
- [**Observability:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/observe/observe-workflow-with-phoenix.html) Monitor and debug your workflows with any OpenTelemetry-compatible observability tool, with examples using [Phoenix](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/observe/observe-workflow-with-phoenix.html) and [W&B Weave](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/observe/observe-workflow-with-weave.html).
- [**Evaluation System:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/evaluate.html) Validate and maintain accuracy of agentic workflows with built-in evaluation tools.
- [**User Interface:**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/quick-start/launching-ui.html) Use the NeMo Agent Toolkit UI chat interface to interact with your agents, visualize output, and debug workflows.
- [**MCP Compatibility**](https://docs.nvidia.com/nemo/agent-toolkit/1.3/workflows/mcp/mcp-client.html) Compatible with Model Context Protocol (MCP), allowing tools served by MCP Servers to be used as NeMo Agent Toolkit functions.

With NeMo Agent Toolkit, you can move quickly, experiment freely, and ensure reliability across all your agent-driven projects.
