Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http hardwaremcp 'https://hardwaremcp.khanex.ai/mcp'

hardwaremcp

Remote endpoint: https://hardwaremcp.khanex.ai/mcp. Paste it into any MCP client: no install, no API key.

Ask your agent "which MCP server should I use for my Bambu P1S?" and it gets the right server, install commands and client config from the HardwareMCP catalog.

An MCP server that helps your AI agent find MCP servers for physical hardware: ESP32, Arduino, Raspberry Pi, RP2040, 3D printers (Bambu, Prusa, Klipper, OctoPrint), Home Assistant, cameras (Frigate, UniFi Protect, ONVIF), Zigbee, serial/BLE and lab gear.

It's a thin layer over the HardwareMCP catalog: 59 servers with install commands and client configs copied from their READMEs.

Tools

ToolWhat it does
search_servers(query, device?, category?)Search the catalog. Results sorted by GitHub stars.
get_server(slug)Full details: what it does, requirements, install commands, client config snippet.
list_devices()Every device family with server counts.
recommend_for_device(device, goal?)Top picks for a device or model (e.g. "Bambu P1S", "Voron", "ESP32-S3"), optionally ranked by a goal.

Use the hosted server (no install)

Endpoint: https://hardwaremcp.khanex.ai/mcp (Streamable HTTP, stateless, no auth, CORS open, JSON responses). POST handles JSON-RPC, OPTIONS returns 204 with CORS headers, and GET/DELETE return 405 because there are no sessions or server-initiated streams.

Claude Code

claude mcp add --transport http hardwaremcp https://hardwaremcp.khanex.ai/mcp

Cursor (~/.cursor/mcp.json)

{ "mcpServers": { "hardwaremcp": { "url": "https://hardwaremcp.khanex.ai/mcp" } } }

Claude Desktop (claude_desktop_config.json)

{ "mcpServers": { "hardwaremcp": { "command": "npx", "args": ["-y", "mcp-remote", "https://hardwaremcp.khanex.ai/mcp"] } } }

Grok Bot (desktop app): there's no settings field for MCP URLs. In a Bot chat, send:

Add a custom MCP server named hardwaremcp at https://hardwaremcp.khanex.ai/mcp

Confirm when asked (no sign-in needed), then type @ and pick hardwaremcp. (Cursor forum answer)

Muse (Meta): ask Muse in chat to create a Custom Connector (Meta Help Center):

Create a Custom Connector for a new remote MCP server, then connect to it:
- Name: hardwaremcp
- Transport: remote streamable HTTP
- URL: https://hardwaremcp.khanex.ai/mcp
- Auth: none (public, no API key or OAuth)
Then list its tools and call list_devices to confirm it works.

Run locally (stdio)

npx -y hardwaremcp   # once published to npm
{ "mcpServers": { "hardwaremcp": { "command": "npx", "args": ["-y", "hardwaremcp"] } } }

Develop

npm install
npm run gen-data      # regenerate src/data.ts from ../hardwaremcp/data/servers.json
npm run build
npm test              # scripted client over stdio
node test-client.mjs https://hardwaremcp.khanex.ai/mcp   # against the live endpoint

Caveat

Install commands come from each project's README and haven't been bench-tested by HardwareMCP. Review code before giving an agent access to your hardware.

Frequently asked questions

What is HardwareMCP?

Find MCP servers for ESP32, Arduino, 3D printers, Home Assistant, cameras and other hardware.

How do I install HardwareMCP?

It runs as a remote server. In Claude Code: claude mcp add --transport http hardwaremcp 'https://hardwaremcp.khanex.ai/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does HardwareMCP need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is HardwareMCP open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains HardwareMCP?

It is published by saadvz. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
