SimplyPrint: 3D Print Farm Management

List MULTIPLE printers with optional filters. For details on a single known printer, call get_printer instead — do not list-then-filter. For farm-wide counts ("how many printers are doing X"), call get_farm_overview instead — do not paginate this. Use status=["online"] to only...

Get details, status, temps, current job, filament, notifications for ONE specific printer by id. Use this (not list_printers) whenever the user asks about a single printer they've already identified — "status of printer X", "what's printer 5 doing", "temperature on Creality K2...

One-shot summary of farm-wide printer state. Use this (NOT list_printers) when the user asks "how many printers are printing/idle/awaiting bed clear/etc." or "what is the state of the farm". Returns a total and {count, printers:[{id,name}]} for each bucket: online, offline, no...

No parameters. Call it with no arguments.

Pause the current print on a printer

Resume a paused print on a printer

Cancel the current print on a printer

Send G-code commands to a printer

Start a print job on one or more printers, now or at a chosen time. File source is exactly one of: file_id (API file hash from upload), filesystem (user-file uid), queue_file (existing queue item id), reprint (previous print-job id), or next_queue_item=true (auto-pick the next...

List every print across the account that is waiting for a scheduled start time, soonest first. Use this for "what is scheduled tonight", "do I have anything queued up for tomorrow", or before rescheduling/cancelling so you can name the right printer. Returns printer, filename,...

Change when a scheduled print starts, or release it immediately. Pass schedule_for with a new absolute instant to move it; omit schedule_for (or send null) to start the print now. Only affects prints still waiting on a scheduled time - a print already staggered or downloading...

Cancel a print that has not started yet - either waiting for its scheduled time or waiting in a staggered start queue - and free the printer. This does NOT cancel a print that is already running; use cancel_print for that.

Home the printer axes (move to origin position)

Move a printer axis to a relative position

Control the printer cooling fans

Enable or disable the printer stepper motors

Set target temperatures (nozzle, bed and/or chamber) on one or more printers - works while idle and mid-print. Values above the printer model maximum are clamped; 0 turns a heater off.

List print queue items with optional filters. Supports filtering by assigned printer(s), group, approval status, tags, queue-item custom-field values, and age. Example: older_than_days=7 for "items added more than 7 days ago", or custom_fields=[{id: "<uuid>", value: "Engineeri...

Get details of a specific queue item

Remove an item from the print queue

Queue a file for printing. Pick exactly one file source: fileId (hex hash from the files.simplyprint.io Upload endpoint) or filesystem (UserFile.uid of an existing library file). Supports PRINT_QUEUE custom fields and a tags object for material colour, nozzle, build plate, or...

Update a queue item (amount, note, custom print time, material usage, printer assignments).

Move a single queue item to a new 1-based position.

Move one or more queue items to a different queue group.

Bring a completed (done) queue item back to the active queue.

DESTRUCTIVE: Delete all items from the queue (optionally filtered by group or done-only). Confirm with the user before calling.

Show which queue items match/miss a specific printer and why. Useful for diagnosing why a queue item will not print.

Calculate the estimated cost of a queue item, optionally for a specific printer.

Find the best-matching queue item(s) for a set of printers using SimplyPrint's compatibility matcher.

Read-only preview: for each given printer, return the next queue item that would be started. Uses the same dedup matcher as create_print_job with next_queue_item=true, so the same queue item is never returned twice across printers in one call. Includes match failures per print...

List all queue groups in the user's account.

Create a new queue group or update an existing one.

No parameters. Call it with no arguments.

Delete a queue group. Optionally move its items to another group via move_to.

Move a queue group to a new position.

List queue items pending approval (status: PENDING, DENIED, or REVISION).

Approve one or more pending/revision/denied queue items, with optional comment.

Deny a pending queue item, either removing it or requesting revisions. Include a comment explaining the decision.

Revoke approval on an already-approved item and send it back to the submitter for revisions.

Resubmit a denied or revision-requested queue item back to pending approval. File-replacement is not supported via MCP.

Retrieve all approval comments on a queue item or user file.

Add a comment (general or feedback) to a queue item or user file. File attachments are not supported via MCP.

Edit an approval comment you authored.

Delete an approval comment you authored (or any comment if you have the permission).

List custom field definitions with pagination and search.

List custom field definitions for a specific entity category and optional sub-category (e.g. PRINT + PRINT_QUEUE for queue-item custom fields).

Set custom field values on one or more entities (queue items, files, printers, etc.). Use this to set a "deadline" or similar field across many queue items at once.

List files and folders in the user's SimplyPrint storage. With pid set, only returns files compatible with that printer (full compatibility check). With global_search=true (default), searches recursively across all folders.

Get a folder's details including permissions.

Estimate the print cost of a file, optionally for a specific printer.

Find which printer models in the account are compatible with a given file.

Set the printers/models/groups a file is assigned to.

Update file metadata such as name and GCODE analysis.

Assign or remove routing tags on a file, including material colour. Use file_id (the UserFile.uid from list_files) and material=[{color, hex, nozzle, ext}] for a colour tag. This tool targets files only (type defaults to 3).

Create a new folder (or edit an existing one with optional org-level permissions).

Delete one or more folders.

Move one or more files to a folder.

Move a folder to another location.

Delete one or more files.

Retrieve slicer settings stored for a file.

List filament spools with optional filters and sorting. Accounts often have hundreds of spools, so ALWAYS pair sort_by with a limit. Use sort_by=last_used + limit=10 for "most used / most popular spool" questions. Use sort_by=created + limit=N for recently added. Use sort_by=l...

Get details of one specific filament spool. Use this (NOT list_filaments+grep) when the user names a spool by id or short id. Accepts spool_id (the integer DB id) or spool_short_id (the 4-character code shown on QR labels and the spool view page, e.g. "T2SO", "M0WT").

Adjust the remaining weight of a filament spool (e.g. after manual weighing).

Assign a filament spool to a printer (or a specific extruder slot).

Remove a filament spool from its printer assignment.

Retrieve the usage history of a filament spool.

Mark a filament spool as freshly dried (resets humidity tracking).

List available filament colors (for UI pickers or picking similar spools).

No parameters. Call it with no arguments.

List filament products from a specific brand.

List past print jobs with pagination, filters, and sort. Compact mode (default) drops gcodeAnalysis, filament breakdowns, and panel-only flags.

Get detailed info for a specific print job.

Archive a print job (hide from default history listings).

Restore an archived print job.

Account-level print statistics (success rate, filament used, print time, cost) with optional date range and user/printer filters.

Referral program statistics: conversions, earnings, pending payout.

No parameters. Call it with no arguments.

Whole-account maintenance overview in one call: counts (in maintenance, scheduled, overdue, open problems, low/out of stock), the single next due job, the 10 most recent jobs, per-printer status and the active maintenance plans. Good for "how is the farm doing"; use list_maint...

No parameters. Call it with no arguments.

List maintenance jobs across the account with filters, paging and sorting — the tool for "what maintenance is outstanding, and on which printer". Each job carries its printer, priority, scheduled date, task progress, assignees and linked problems. Returns 10 per page by defaul...

Everything known about one printer's maintenance: current status, health (last maintenance, days since, open problem count, active job), lifetime print and maintenance stats, the last 50 jobs, per-task completion history and spare parts consumed. The only source of a PREDICTED...

List reported printer problems with their description, problem type, reporter, status and age — get_maintenance_dashboard returns only an open-problem count, none of this. Returns 10 per page by default; raise page_size (max 100) or advance page.

Full detail for one maintenance job: the task checklist with per-task completion, assignee and spare-part requirement, the printer's stats since its last maintenance, the problems linked to the job, and other unresolved problems on the same printer. Task checklists and spare-p...

List maintenance spare parts with stock level, low-stock threshold, SKU, category, cost and the printer models each part fits. Requires the Maintenance Inventory plan feature: without it this tool fails with an explicit "your account doesn't have access to this feature" error,...

Cheapest fleet-wide maintenance check; takes no parameters. Returns an object keyed by printer id, each entry holding status (in_maintenance, due, scheduled, or operational when only problems are open), next_scheduled_date and open_problems (the number of reported problems not...
