Connect SimplyPrint to any AI assistant via MCP

Connect SimplyPrint to any AI assistant via MCP


SimplyPrint ships an official MCP server, which means any AI assistant that speaks MCP (Model Context Protocol) can plug straight into your account. Ask Claude, ChatGPT, Gemini, Cursor or any other MCP-aware assistant to pause a print, approve pending queue items, mark a spool as freshly dried, or check this week's success rate - things you'd normally click in the panel, now spoken in plain English.


MCP is an open standard used by Claude, ChatGPT, Gemini and most modern AI assistants. If your assistant supports "custom connectors", "MCP servers" or similar, it works with SimplyPrint.


Listed on the official MCP Registry


SimplyPrint is published on the official Model Context Protocol registry as io.simplyprint/simplyprint. Some AI clients can discover SimplyPrint by browsing their built-in MCP server directory, so if your client offers an "add MCP server" search, try searching for "simplyprint" before pasting anything.


If your client does not yet support registry browsing, the URL below works in every MCP-aware client either way.


The MCP URL


One URL works in every MCP client:


https://simplyprint.io/api/mcp


Paste it into your assistant's connector settings and approve the OAuth consent screen. That's the whole integration.


What you can ask your assistant


Once connected, your assistant can do (almost) anything you can do in the SimplyPrint panel. A few examples:


Printers

  • "What's printing right now?"
  • "Pause the print on the Bambu P1S."
  • "Home all three axes on Printer 4."
  • "Send M104 S210 to the Prusa to preheat the nozzle."


Print queue

  • "Move all PETG jobs to the bottom of the queue."
  • "Approve the three pending items from Sarah."
  • "Queue five copies of benchy.gcode for tomorrow."
  • "Which printer in the shop can print the next item fastest?"


Files

  • "Find every file tagged 'prototype' and delete them."
  • "Estimate the cost of printing battery-holder.gcode on the X1C."
  • "Move all STLs in 'sandbox' into the 'archive' folder."


Filament

  • "Which spools are below 100 grams?"
  • "Mark the orange PLA as freshly dried."
  • "Adjust the remaining weight on spool 42 to 820 grams."


Stats and history

  • "What was our print success rate last month?"
  • "How much filament did we use this week?"
  • "Show me the details of yesterday's longest print."


If your assistant isn't sure whether something is possible, just ask. It can see the full list of available actions once connected.


How the connection works


The connection uses OAuth - the same secure login flow you use for signing into apps with Google or GitHub. You never paste an API key into a chatbot, and you can revoke access any time.


Here's what happens under the hood:


  1. You paste the SimplyPrint MCP URL into your AI assistant's integrations or connector settings.
  2. The assistant opens a SimplyPrint login page.
  3. You log in and approve a list of permissions (called "scopes") - read printers, manage the queue, and so on.
  4. The assistant gets a token tied to your account with exactly the permissions you approved. Nothing more.
  5. You're connected. Ask your assistant whatever you want.


Supported AI assistants


Every client sets up its custom connector slightly differently. We have a dedicated guide for Claude below; for other clients, follow your client's own "add MCP server" or "custom connector" docs and point it at the URL above. The connection itself is identical in every case.


Claude (claude.ai, Claude Desktop, Claude Code)


Anthropic's Claude works in three places - the web app at claude.ai, the Claude Desktop app, and the Claude Code terminal assistant. The setup for each is covered in Connect SimplyPrint to Claude.


Custom connectors on claude.ai and Claude Desktop require a Claude Pro, Max, Team or Enterprise plan. Claude Code works on any Claude plan.


ChatGPT


ChatGPT supports MCP via its custom connectors feature. In ChatGPT, open a new chat, click the connector icon, and add a custom connector pointing at https://simplyprint.io/api/mcp.


We have submitted SimplyPrint to the ChatGPT App Directory. Once it is approved you will be able to install it in one click instead of pasting the URL.


Google Gemini CLI


Install the official SimplyPrint extension: gemini extensions install SimplyPrint/simplyprint-gemini-extension. Or point any MCP-capable Gemini surface at https://simplyprint.io/api/mcp directly if you would rather skip the extension wrapper. Full walkthrough: Connect SimplyPrint to Gemini CLI.


Cursor, Windsurf, Cline, Zed and other editors


Any editor or tool that supports remote MCP servers can connect. Look for "MCP servers" or "custom connectors" in its settings, add a new one, and paste the URL above. The OAuth flow opens in your default browser.


Self-hosted chat frontends


Any tool that implements the MCP client spec (including open-source chat frontends and agent frameworks) can connect. Consult your client's docs for how to add a custom MCP server, then use the same URL.


What the assistant can and cannot do


Each permission (scope) grants the assistant a specific slice of your account. Only grant what the assistant actually needs.


Permission

What it lets the assistant do

View your printers' details

See printer names, status, current print, bed temperature, etc.

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, comment

View your files and folders

List files, search by name, estimate costs

Manage your files and folders

Move, rename, delete, create folders, set printer assignments

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


The assistant cannot change your subscription, delete your account, pay invoices, or see any data outside the scopes you granted. Billing and account-deletion are deliberately off-limits.


Security and revoking access


OAuth is safer than pasting an API key, because:


  • The token is scoped to exactly the permissions you approved.
  • The token is bound to your user - not to your account admin or anyone else.
  • You can revoke access at any time and the assistant instantly stops working.


To revoke, go to Account settings > Connected apps. You'll see every connected assistant, the scopes it was granted, and when it last made a request. Click Revoke to disconnect.


Revoking is instant and can't be undone. The assistant will need to go through the login flow again next time you want to use it.


Frequently asked questions


Does my data train the AI?

No. Data you send through your assistant goes to the assistant's servers (Anthropic, OpenAI, etc.) per their own data policies. It does not train SimplyPrint's systems. Check your assistant's own privacy settings if you're concerned.


Can the assistant start a print without asking me?

It depends on which scopes you granted. If you granted "Operate your printers", yes, it can - but most assistants will still confirm destructive actions with you first. For extra safety, skip the "Manage" scopes and only grant "View" scopes if you want a read-only connection.


What does it cost?

Using the MCP is free and included in your SimplyPrint plan. API calls from the assistant count against your normal usage.


Can multiple assistants connect at once?

Yes. Each one gets its own token with its own scopes, and you can revoke any of them independently.


What if a new tool is added?

New tools are added periodically as SimplyPrint gains features. Your connected assistants pick them up automatically the next time they refresh the tool list - no re-connecting needed.


Does this work with the mobile app?

The MCP is a server-side integration, so it doesn't depend on the mobile app. As long as your SimplyPrint account is active, any MCP client on any device can connect.


My assistant isn't listed above - will it work?

If it says it supports MCP (sometimes called "custom connectors" or "tool servers"), yes. The URL is the same. If you hit snags, send us the assistant's name and any error message and we'll take a look.
