SimplyPrint: 3D Print Farm Management

Delete one or more files.

Delete one or more folders.

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

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

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

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

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

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

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, not_connected, operational (idle), printing, paused, awaiting_bed_clear (a print finished but the bed has not been cleared yet — printer is online + operational + still has a job; this is NOT print_pending), in_maintenance, print_pending (a queued staggered/scheduled start), requires_attention (has unresolved error notifica…

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").

Retrieve the usage history of a filament spool.

Get a folder's details including permissions.

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_maintenance_jobs for anything that needs filtering, paging or more than the 10 most recent jobs. Note low_stock_parts is silently [] when the account lacks the Maintenance Inventory feature — list_spare_parts says so explicitly instead.

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-part requirements are available nowhere else over MCP. Pass the job id as job_id (list_maintenance_jobs returns it as "id"); each task's id is what the task tools take as task_id.

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 yet resolved). Only printers with a scheduled or in-progress job or an open problem appear, so a printer that is absent has nothing outstanding and an empty object means nothing is scheduled or reported anywhere. Follow up with get_printer_maintenance_profile for one printer, or list_maintenance_jobs for job-level detail…

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 printer (issues) so you can explain why a printer has nothing to print. Does NOT start any job.

For a partner, reseller, OEM or Enterprise group account: maintenance across every account it services. Returns counters (in maintenance, scheduled, overdue, open problems, open alerts, out of order, accounts needing a visit), one row per serviced account (printers, open problems, overdue jobs, next scheduled job, next visit, agreement), the most recent open problems, and the accounts due a visit. Fails on an account that is not a partner with the maintenance module.

Get detailed info for a specific print job.

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". Cheaper and less noisy than listing all printers.

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 next-due date — when nothing is scheduled yet, health.next_scheduled_job is filled from the matching maintenance plan and carries is_predicted=true with a null id. Large response: ask for one printer at a time, and use get_maintenance_status_map for fleet-wide questions.

Get details of a specific queue item

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

Referral program statistics: conversions, earnings, pending payout.

Retrieve slicer settings stored for a file.

Get one or more realistic sample webhook payloads for a specific event type, matching the envelope a live webhook delivery would produce. Used by integration platforms (Activepieces, n8n, Zapier) to show the payload shape before any real event fires. Falls back to synthetic data when no applicable entity exists in the account.

Home the printer axes (move to origin position)

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

For a partner account: serviced accounts due a maintenance visit under their agreed visits per year, soonest first, with visits used this year, the next booked visit, and whether it is overdue. Suggestions only; nothing is booked.

List filament products from a specific brand.

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).

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

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=left for emptiest/fullest. Filters (material_type/brand/color) are case-insensitive substring matches. If the user names a specific spool by id or 4-character short id (e.g. "T2SO"), call get_filament instead — do NOT list and grep. Amount-remaining fields: report weight from leftGrams/totalGrams (grams) and percentLeft (%…

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.

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 default; raise page_size (max 100) or advance page. IMPORTANT: a returned job status may read "overdue", but that value is DERIVED (a scheduled job whose scheduled_date has passed) and is NOT accepted by the status filter — ask for status "scheduled" and read each job's returned status, or use the dashboard's overdue count.

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.

For a partner account: its maintenance "needs attention" inbox - alerts its escalation rules opened for serviced accounts (problem thresholds, printers out of order too long, overdue jobs, visits due). Open alerts by default; status can be acknowledged, resolved, unresolved or all. Each alert has a human-readable message.

For a partner account: its maintenance visits to serviced accounts. Open visits (proposed, confirmed, in progress) by default, soonest first; filter by status, company_id or a from/to date range.

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

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

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 see reachable printers, status=["printing"] for ones actively printing, status=["was_printing_when_offline"] for printers that dropped mid-print, status=["idle"] for available printers ready to accept a job, status=["awaiting_bed_clear"] for printers whose last print finished but the bed has not been cleared yet (NOT pri…

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: "Engineering"}] for a specific department field.

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

List all queue groups in the user's account.

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, scheduled_for and who scheduled it. Prints already released and starting are NOT listed here - use get_farm_overview for those.

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, so an empty list here always means the account genuinely has no matching parts. (get_maintenance_dashboard cannot tell you that — its low_stock_parts is silently [] both when the feature is missing and when stock is healthy.)

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

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

Move one or more files to a folder.

Move a folder to another location.

Move a printer axis to a relative position

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

Pause the current print on a printer

Remove an item from the print queue

Move a queue group to a new position.

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

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 cannot be pushed back.

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

Resume a paused print on a printer

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

Create a new queue group or update an existing one.

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

Send G-code commands to a printer

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.

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

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.

Mark a task as skipped rather than done - it was not needed this time. Reversible with unskip_maintenance_task.

Move a scheduled maintenance job to in-progress, putting the printer into maintenance mode so AutoPrint stops sending it work. Only works on a job in "scheduled" status. This is the safe direction: it takes a printer OUT of rotation.

Restore an archived print job.

Remove a filament spool from its printer assignment.

Reopen a task that was ticked off by mistake. The undo for complete_maintenance_task.

Undo a skip, putting the task back on the job as outstanding.

Update file metadata such as name and GCODE analysis.

Edit an approval comment you authored.

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