Connect SimplyPrint to Claude (claude.ai and Claude Code)

Connect SimplyPrint to Claude (claude.ai and Claude Code)


SimplyPrint has an official MCP server, which means you can plug it straight into Claude and just tell Claude what to do with your printers, queue, files and filament. This guide walks through connecting SimplyPrint to both flavours of Claude: the web app at claude.ai (and the Claude desktop app) and the Claude Code CLI.


You need a Claude account that supports custom connectors. On claude.ai that is currently the Pro, Max, Team and Enterprise plans. Claude Code works on any plan.


What you can do once connected


Once Claude has the SimplyPrint connector, you can ask things like:


  • "What's printing right now across all my printers?"
  • "Pause every printer - I need to swap filament."
  • "Queue five copies of benchy.gcode on the Bambu."
  • "Show me what went wrong with the last three failed prints."
  • "Which spools have less than 100 grams left?"


Claude picks the right SimplyPrint action, asks you to confirm anything destructive, and reports back in plain English.


Connect claude.ai (web and desktop app)


The steps below use the web app at claude.ai. The Claude desktop app has the same Connectors screen, so the flow is identical.


1. Open Claude


Head to claude.ai and sign in.

2. Open the Customize menu


In the left sidebar, click Customize.

3. Open Connectors


In the Customize menu, select Connectors. This is where Claude lists every tool it can connect to, including official connectors and your own custom ones.

4. Add a custom connector


Click the + button, then choose Add custom connector. Fill in the form:



Leave advanced settings at their defaults and click Add.

We have submitted SimplyPrint to Anthropic's official plugin directory for Claude Code and Cowork. Once approved you will be able to install it in one click from Claude's plugin store. For claude.ai web and desktop, the custom-connector step above is the supported route for now; we may pursue listing in the Claude.ai Connectors Directory later.


5. SimplyPrint appears in your connectors


Claude now shows SimplyPrint in the Connectors list, ready to use.

6. Ask Claude something that uses SimplyPrint


Start a new conversation and ask something printer-related, like "What's printing right now?". The first time Claude needs to call a SimplyPrint tool, it asks for permission.

7. Approve access in SimplyPrint


A SimplyPrint login window opens. Log in (if you are not already) and you land on the SimplyPrint consent screen, showing the scopes Claude is asking for - read printers, manage queue, and so on. Approve the ones you are happy with and click Authorize.

Only grant the scopes you actually want Claude to have. You can leave "Manage" scopes off for a read-only connection, and you can revoke access any time from Account settings > Connected apps.


8. Claude responds using your SimplyPrint data


The window closes and Claude completes its answer using live data from your SimplyPrint account.

That's it - you are connected. You never need to redo this flow; Claude remembers the connection until you remove it.


Connect Claude Code (CLI)


Claude Code is Anthropic's command-line coding assistant. SimplyPrint ships as a first-party plugin on the Claude Code marketplace.


Install the plugin


From any Claude Code session, run:


/plugin marketplace add simplyprint/simplyprint-claude-plugin


/plugin install simplyprint@simplyprint


/reload-plugins


The first command registers the SimplyPrint marketplace. The second installs the plugin itself. The third picks up the new slash commands and tools in your current session; if you skip it, restart Claude Code instead. You only need to do this once per machine.


First-time OAuth


The first time you invoke any SimplyPrint tool in Claude Code, it opens a browser window for OAuth - the same consent screen shown above. Approve the scopes you want and Claude Code caches the token locally.


What you get


The plugin bundles:


  • The SimplyPrint MCP server, so tools like list_printers, pause_print, home_printer, send_gcode, list_queue become available to Claude
  • Starter slash commands: /simplyprint:farm-status, /simplyprint:queue-print, /simplyprint:pause-all, /simplyprint:printer-detail


You can ask Claude Code things like "give me a one-line status for every printer in the shop" or "pause all printers, I need to change filament" and it will drive SimplyPrint for you.


Claude Desktop


Claude Desktop uses the exact same Connectors screen as claude.ai. Follow the eight-step flow above - the screenshots match what you see in the desktop app.


Scopes Claude asks for


When you authorize SimplyPrint from Claude, you get a checklist of scopes. Approve only what you want.


Scope

What it lets Claude do

View your printers' details

See names, status, current print, bed temperature

Operate your printers

Pause, resume, cancel, home, send G-code

View your print queue

List queue items, view details, see pending approvals

Manage your print queue

Add items, reorder, edit, delete, approve, deny

View your files and folders

List files, search by name, estimate print cost

Manage your files and folders

Move, rename, delete, create folders

View filament spools

See remaining weight, assignments, drying status

Manage filament spools

Adjust weight, assign to printers, mark dried

View your print history

See past jobs, success/failure, filament used

Manage your print history (archive, restore)

Archive and unarchive jobs

View your print statistics

Success rate, filament totals, cost summaries

View your custom fields

List field definitions (deadline, order number, etc.)

Manage your custom fields and their values

Set values across queue items (sort by deadline, etc.)

View your slicer profiles

Look up which slicer settings were used on a file


Claude cannot change your subscription, delete your account, pay invoices, or do anything outside the scopes you granted. Billing and account-deletion are off-limits to every connected app.


Revoking access


To disconnect Claude, go to Account settings > Connected apps in SimplyPrint and click Revoke next to the Claude entry. The connection stops working immediately. If you want to use Claude with SimplyPrint again afterwards, you just run through the authorization flow once more.


Troubleshooting


Claude does not offer SimplyPrint as a tool.

Check that the connector actually appears in Customize > Connectors. If it is greyed out, your Claude plan may not support custom connectors - you need Pro, Max, Team or Enterprise.


Authorization window closes without doing anything.

Make sure pop-ups are enabled for claude.ai. Some browsers block the SimplyPrint login window silently.


Claude says it cannot perform an action.

Most likely the scope was not granted. Revoke access in SimplyPrint, trigger a SimplyPrint action in Claude again, and approve the missing scope on the consent screen.


Claude in Claude Code does not see SimplyPrint tools.

Run /plugin to open the plugin manager and check the Installed tab for simplyprint@simplyprint. If it is not listed, re-run the install commands above. If it is listed but the tools are missing, run /reload-plugins or restart Claude Code.
