The Simple Agent Development Kit

Join the project community on our server!

Nerve is a simple yet powerful Agent Development Kit (ADK) to build, run, evaluate, and orchestrate LLM-based agents using just YAML and a CLI. It’s designed for technical users who want programmable, auditable, and reproducible automation using large language models.

Key Features

📝 Declarative Agents

Define agents using a clean YAML format: system prompt, task, tools, and variables — all in one file.

🔧 Built-in Tools & Extensibility

Use shell commands, Python functions, or remote tools to power your agents. Tools are fully typed and annotated.

🌐 Native MCP Support (Client & Server)

Nerve is the first framework to let you define MCP servers in YAML — and act as both client and server, enabling agent teams and deep orchestration.

📊 Evaluation Mode

Benchmark your agents with YAML, Parquet, or folder-based test cases. Run reproducible tests, log structured outputs, and track regression or progress.

🔁 Workflows

Compose agents into simple, linear pipelines to create multi-step automations with shared context.

🧪 LLM-Agnostic

Built on LiteLLM, Nerve supports OpenAI, Anthropic, Ollama, and dozens more — switch models in one line.
