io.simplyprint/simplyprint

Tools

• add_queue_comment

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

  shallow
• add_to_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.

  shallow
• adjust_filament_weight

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

  shallow
• approve_queue_item

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

  shallow
• archive_print_job

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

  shallow
• assign_filament

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

  shallow
• assign_maintenance_task

  Assign a maintenance task to a user, or pass no user_id to unassign it. Set notify true to tell them.

  shallow
• assign_tags

  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).

  shallow
• cancel_maintenance_job

  Cancel a maintenance job that is not going to happen. If it was in progress this also returns the printer to the AutoPrint rotation. Not the same as completing it: no work is recorded and schedule counters are not reset.

  shallow
• cancel_print

  Cancel the current print on a printer

  shallow
• cancel_scheduled_print

  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.

  shallow
• complete_maintenance_job

  Close a maintenance job as done. This RETURNS THE PRINTER TO THE AUTOPRINT ROTATION, so only call it when the work has actually been carried out - confirm with the user first. Optionally pass completion_summary, and resolve_problem_ids to close the problems this job fixed.

  shallow
• complete_maintenance_task

  Tick one task off a maintenance job. Does NOT complete the job or return the printer to the AutoPrint rotation - use complete_maintenance_job for that once every task is done. If the task is tied to a spare-part category you must pass selected_spare_part_id, or skip_spare_part true; completing it decrements that part's stock.

  shallow
• create_folder

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

  shallow
• create_print_job

  Start a print job on one or more printers. 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 matching queue item per printer, deduplicated across printers). Supports PRINT_JOB custom fields (shared and per-printer). Auto-starts when the account's autostartPrints setting is on (default).

  shallow
• delete_file

  Delete one or more files.

  shallow
• delete_folder

  Delete one or more folders.

  shallow
• delete_queue_comment

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

  shallow
• delete_queue_group

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

  shallow
• deny_queue_item

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

  shallow
• empty_queue

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

  shallow
• estimate_file_cost

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

  shallow
• get_account_statistics

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

  shallow
• get_farm_overview

  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 notifications), ai_running, ai_detected_low, ai_detected_high. Counts overlap intentionally: a printer can be in "online" + "printing" + "ai_running" at once.

  shallow
• get_filament

  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").

  shallow
• get_filament_history

  Retrieve the usage history of a filament spool.

  shallow
• get_folder

  Get a folder's details including permissions.

  shallow
• get_maintenance_dashboard

  Overview of maintenance jobs, problems, inventory, and printer maintenance status.

  shallow
• get_maintenance_job

  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.

  shallow
• get_maintenance_status_map

  Cheapest fleet-wide maintenance check; takes no parameters. Returns an object keyed by printer id, each entry holding status (in_maintenance, due or scheduled) and next_scheduled_date. Only printers with a scheduled or in-progress job appear, so a printer that is absent has no maintenance outstanding and an empty object means nothing is scheduled anywhere. Follow up with get_printer_maintenance_profile for one printer, or list_maintenance_jobs for job-level detail.

  shallow
• get_next_queue_item

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

  shallow
• get_next_queue_items_for_printers

  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.

  shallow
• get_partner_maintenance_overview

  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.

  shallow
• get_print_job

  Get detailed info for a specific print job.

  shallow
• get_printer

  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.

  shallow
• get_printer_maintenance_profile

  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.

  shallow
• get_queue_item

  Get details of a specific queue item

  shallow
• get_queue_item_cost

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

  shallow
• get_referral_stats

  Referral program statistics: conversions, earnings, pending payout.

  shallow
• get_slicer_settings_for_file

  Retrieve slicer settings stored for a file.

  shallow
• get_webhook_sample

  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.

  shallow
• home_printer

  Home the printer axes (move to origin position)

  shallow
• inspect_printer_queue

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

  shallow
• list_accounts_due_maintenance_visit

  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.

  shallow
• list_brand_filaments

  List filament products from a specific brand.

  shallow
• list_custom_fields

  List custom field definitions with pagination and search.

  shallow
• list_custom_fields_for

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

  shallow
• list_filament_colors

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

  shallow
• list_filaments

  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 (%), NOT the raw total/left which are internal filament LENGTH in mm. density (g/cm³) is the value used for the gram conversion; densityIsEstimated=true means the spool has no material profile so a default density was assumed.

  shallow
• list_files

  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.

  shallow
• list_maintenance_jobs

  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.

  shallow
• list_maintenance_problems

  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.

  shallow
• list_partner_maintenance_alerts

  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.

  shallow
• list_partner_maintenance_visits

  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.

  shallow
• list_pending_queue_items

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

  shallow
• list_print_jobs

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

  shallow
• list_printers

  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 print_pending, which means a queued staggered start).

  shallow
• list_queue

  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.

  shallow
• list_queue_comments

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

  shallow
• list_queue_groups

  List all queue groups in the user's account.

  shallow
• list_scheduled_prints

  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.

  shallow
• list_spare_parts

  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.)

  shallow
• mark_filament_dried

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

  shallow
• match_file_to_printers

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

  shallow
• move_file

  Move one or more files to a folder.

  shallow
• move_folder

  Move a folder to another location.

  shallow
• move_printer_axis

  Move a printer axis to a relative position

  shallow
• move_queue_item

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

  shallow
• pause_print

  Pause the current print on a printer

  shallow
• remove_from_queue

  Remove an item from the print queue

  shallow
• reorder_queue_group

  Move a queue group to a new position.

  shallow
• reorder_queue_item

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

  shallow
• reschedule_print

  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.

  shallow
• resubmit_queue_item

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

  shallow
• resume_print

  Resume a paused print on a printer

  shallow

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

  shallow
• save_queue_group

  Create a new queue group or update an existing one.

  shallow
• send_back_for_revision

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

  shallow
• send_gcode

  Send G-code commands to a printer

  shallow
• set_custom_field_values

  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.

  shallow
• set_file_printers

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

  shallow
• set_printer_fans

  Control the printer cooling fans

  shallow
• set_printer_motors

  Enable or disable the printer stepper motors

  shallow
• set_printer_temperatures

  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.

  shallow
• skip_maintenance_task

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

  shallow
• start_maintenance_job

  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.

  shallow
• unarchive_print_job

  Restore an archived print job.

  shallow
• unassign_filament

  Remove a filament spool from its printer assignment.

  shallow
• uncomplete_maintenance_task

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

  shallow
• unskip_maintenance_task

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

  shallow

  shallow
• update_queue_comment

  Edit an approval comment you authored.

  shallow
• update_queue_item
