Installation#

Use this page when you are consuming a published NeMo Relay release from a package manager.

If you are working from a source checkout, validating unpublished changes, or contributing to the repository, use Development Setup instead.

CLI#

Install the NeMo Relay CLI when you want the nemo-relay executable for coding-agent hook and LLM gateway observability.

cargo install nemo-relay-cli@0.3.0

Python#

Install the Python package when your application uses NeMo Relay through the Python wrapper.

uv add nemo-relay@0.3.0

Use uv add from an application project that has a pyproject.toml; it records nemo-relay as a project dependency. If you are only installing into an active virtual environment and do not have project metadata, use uv pip install nemo-relay instead. You can also use pip install nemo-relay if you are not managing the environment with uv.

Node.js#

Install the Node.js package when your application uses NeMo Relay through the JavaScript API.

npm install nemo-relay-node

Rust#

Add the Rust crates when your application uses NeMo Relay directly from Rust.

cargo add nemo-relay@0.3.0
cargo add nemo-relay-adaptive@0.3.0

  • nemo-relay provides the core runtime APIs for scopes, middleware, subscribers, plugins, tool calls, and LLM calls.

  • nemo-relay-adaptive provides adaptive runtime primitives and Redis-backed learning components when you want adaptive tuning behavior in Rust.

Integrations#

Install integration packages when your application already uses one of the supported framework or agent harness surfaces.

OpenClaw#

Install the OpenClaw plugin through OpenClaw so OpenClaw can register and manage the package:

openclaw plugins install npm:nemo-relay-openclaw@0.3.0
openclaw gateway restart

Use the package name nemo-relay-openclaw for installation. Use the plugin ID nemo-relay in OpenClaw configuration, inspection, and gateway status commands. See the OpenClaw Plugin Guide for configuration and verification steps.

Python Framework Integrations#

Install the Python package with the supported framework extras when your application uses LangChain, LangGraph, or Deep Agents.

uv add "nemo-relay[langchain,langgraph,deepagents]@0.3.0"

The extras install the NeMo Relay Python package plus the dependencies needed by the maintained public integrations. See Supported Integrations for guide links and support levels.
