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
• 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
• 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_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_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_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_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_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
• 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

  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.
