MCP server nodrix

nodrix

The IoT platform Cloudflare didn't build. Point your hardware at one endpoint over HTTPS or WebSocket, watch variables appear on their own, build realtime drag-and-drop dashboards, automate, and read it all back through a clean API — entirely on infrastructure you own. nodrix is single-tenant and open source: it deploys into your Cloudflare account on Workers, Durable Objects, D1, and R2.

Features

• 📡 Telemetry over HTTPS or WebSocket — hardware POSTs JSON to a project; variables auto-create on first sight. No schema to define, no MQTT broker to run.
• 📊 Realtime dashboards — a drag-and-drop widget grid streams updates over hibernating WebSockets; share any dashboard read-only by public link.
• 🧩 Embeddable widgets — every widget is a framework-agnostic Web Component you can lift straight into your own app.
• 🎮 Two-way control — toggles, sliders, color pickers, and buttons write values back to hardware via short polls or a control socket.
• 🤖 Visual automations — variable, schedule, sunrise/sunset, and event triggers run conditions and actions: webhooks, code snippets, and service integrations.
• 🔌 Integrations — fan out to HTTP, email, and chat (Slack, Telegram, Discord, and more).
• 📖 Clean read API — latest state, time-series, and variable listings behind one token.
• 🧠 Native MCP server — read telemetry and control hardware from an AI assistant, on devices you are not physically next to. Owner-gated and off by default; see AI assistants (MCP).
• 👥 Multi-user — owner / admin / member roles, email invites, and social sign-in (Google, GitHub).
• 📝 Audit log — every privileged action recorded and paginated in the UI.

Quick start

1. Deploy to your Cloudflare account — one click, or bun run deploy:platform from a clone.

2. Create the owner account — the first visit prompts a "Create owner account" page; the first signup becomes owner.

3. Create a project and mint a project token from the dashboard.

4. Send telemetry — variables are created the moment data arrives:

   curl -X POST https://<your-worker>/v1/telemetry \
     -H "Authorization: Bearer $NODRIX_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"metrics":{"temperature":23.4,"humidity":61}}'
   

5. Read it back:

   curl https://<your-worker>/v1/projects/<project>/state \
     -H "Authorization: Bearer $NODRIX_TOKEN"
   

AI assistants (MCP)

nodrix ships a native Model Context Protocol server, so an assistant can read a project's telemetry and — once you allow it — act on the hardware. Because devices report to your deployment rather than to your laptop, the board does not need to be plugged into the machine running the assistant; it can be in another building.

Two endpoints, both Streamable HTTP:

Endpoint	Auth	For
/v1/mcp	Bearer token	CLI and IDE clients
/v1/mcp/oauth	OAuth	claude.ai-style connectors

Both are off by default. The owner flips them in Settings → More:

• mcp_enabled — the master switch. While it is off, /v1/mcp returns 404, so a disabled server looks absent rather than merely forbidden.
• mcp_write_enabled — gates the management and control tools. Until it is on, even an admin-scope token gets read-only tools, so an assistant cannot command hardware by default.

12 read tools — list_projects, list_variables, get_state, get_series, list_dashboards, get_dashboard, list_widget_types, list_widgets, list_block_types, list_integration_kinds, list_automations, list_integrations.

16 write tools — creating and updating projects, variables, dashboards, widgets, automations, and integrations, plus set_variable (how an assistant turns a relay on), run_automation, emit_event, and test_integration.

There are no delete tools, by design. Every tool resolves its target project through the token's scope before it runs, so it cannot reach a project the token cannot.

Architecture

• Worker (worker/) — a single Hono app. Durable Objects for Project, Dashboard, Scheduler, and the MCP agent; one Workflow for provisioning; D1 (metadata), R2 (telemetry history), KV (read cache + JWKS).
• Web (web/) — Vue 3 + Tailwind + Reka UI admin panel and drag-and-drop dashboard builder, built and served as Worker static assets.
• Shared (shared/) — framework-agnostic Web Component widgets, the integration catalog, and automation blocks, consumed by both web and worker so there is a single source of truth.
• Deploy (deploy/) — the small config carrier behind the one-click Deploy to Cloudflare.

worker/   Cloudflare Worker — API, Durable Objects, Workflow
web/      Vue 3 admin panel + dashboard builder
shared/   Web Component widgets, integration catalog, automation blocks
deploy/   One-click Deploy to Cloudflare config
scripts/  Build, version, and migration generators

Storage

Store	Holds
Project DO (SQLite)	Latest variable state, recent ring buffer, pending control writes, flush cursor
R2	Cold telemetry history (NDJSON, partitioned by project + hour)
D1	Users, sessions, accounts, projects, variables, dashboards, tokens, automations, integrations, audit log, OAuth provider config (metadata only — never any telemetry point)
KV	Cached /state responses and JWKS
Dashboard DO	Per-dashboard subscriptions + hibernated WebSockets
Scheduler DO	One alarm at the next schedule/sunset automation fire time

Authentication

Better Auth handles sign-in. Email + password is on by default; Google and GitHub OAuth can be enabled at runtime from Settings → Sign-in providers (the owner enters a client ID + secret per provider, and the login page shows the matching buttons immediately).

The first signup on a fresh deployment becomes owner. After that, registration is closed: the owner invites people from Users, each with an owner / admin / member role. Sessions are cookie-based and persist 30 days; each device is a separate session, listed and revokable from Users.

Development

nodrix uses Bun.

bun install
bun run dev              # worker (wrangler dev)
bun run dev:web          # web (vite)
bun run typecheck
bun run build
bun run deploy:platform  # build + deploy the worker
