DAppNode 0.3.23 is out It ships Nexus Chat — a built-in assistant that lives inside the UI. Reads your logs. Debugs your stack. Installs packages. Asks before it changes anything. Your node, now with a copilot

Nexus Chat isn't a chatbot bolted on. It runs against your node. It sees your installed packages, your logs, your system info. It's grounded in DAppNode's own docs. What it can do:

→ Debug: read logs, find the cause → Install: search and install packages → Configure: env vars, ports, staker settings → Lifecycle: start, stop, restart → Confirm: every action shows a card before it runs

Power users: DAppNode also exposes a `POST /mcp` endpoint, so any MCP client (Claude Desktop, Cursor, custom agents) can talk to your Dappnode directly. Read-only by default; mutating tools opt-in.

Your Nexus API key works beyond Nexus Chat: point any OpenAI-compatible client at `nexus-api.dappnode.com/v1` and you're routing through Nexus. Works in OpenClaw + Hermes Agent (Dappnode packages) and OpenCode (open-source dev tool). Plus anything else that takes a base URL + key.
