Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_printersA | FREE. Discovery for FabTally 3D printing: returns the live 12-printer FDM fleet (printer id, human name, bed/build-volume in mm, nozzle diameter), the 12 supported filament materials (PLA, PETG, ABS, ASA, Nylon, PC, TPU + carbon-fiber variants), and the x402 pricing tiers for the paid slice/quote/DFM tools. No payment required. Call this FIRST to choose a |
| check_printabilityA | 3D printing DFM / design-for-manufacturability & printability check for an STL/3MF/OBJ model. Default (full=false) is FREE: a geometry-only preview — printable verdict (yes / with-warnings / no), watertight/manifold check, dimensions & volume, fits-on-bed, a wall-thickness estimate vs the 0.4mm nozzle, and an overhang/support heuristic. No payment needed. Set full=true for the PAID full DFM report ($0.01 USDC on Base, x402): everything above PLUS EXACT support-material grams/time and infill material-saving deltas from REAL OrcaSlicer slices, every field labelled exact vs heuristic. Without payment the paid mode returns the x402 challenge (price + how to pay); pass |
| optimize_orientationA | PAID ($0.02 USDC on Base, x402). Orientation optimiser for FDM 3D printing: really slices up to 4 candidate build orientations with automatic supports on the chosen printer and recommends the one that uses the LEAST support material (exact, slice-derived), reporting the filament/support savings vs printing the model as-is. Reduces support waste, print time, and post-processing. Costs more than other tools because it runs multiple real slices. Without payment, returns the x402 challenge (price + how to pay); pass |
| analyze_modelA | PAID ($0.002 USDC on Base, x402). Geometry only, no slice: bounding box (mm), volume (cm3), triangle count, watertight flag, and a fits-on-bed check for an optional printer. Cheap sanity check for an STL/3MF/OBJ model. Without payment, returns the x402 challenge (price + how to pay). |
| get_print_quoteA | PAID ($0.005 USDC on Base, x402). Slicer-accurate FDM 3D-printing price quote from a real OrcaSlicer slice (not an estimate): print time, filament grams, and a priced quote (material + machine time + setup, with automatic volume discounts). Upload an STL/3MF/OBJ/STEP model. Without payment, returns the x402 challenge (price + how to pay). |
| slice_modelA | PAID (x402, USDC on Base). Full OrcaSlicer slice on any of the 12 FDM printers: print time, filament grams, layer count, geometry, and fits-on-bed. Optionally returns a preview PNG render and/or the sliced G-code. Price tiers by outputs: base $0.005; +preview PNG $0.01; +G-code $0.015; +preview+G-code $0.02. Upload an STL/3MF/OBJ/STEP model. Without payment, returns the x402 challenge for the selected tier. |

Scored across 6 tools
Most tools have clearly distinct purposes: discovery, DFM check, orientation optimization, cheap geometry analysis, quote, and slicing. However, check_printability (in free mode) and analyze_model both perform geometry-only sanity checks (dimensions, watertight, fits-on-bed), which could cause an agent to pick the wrong one despite the price and detail differences.
All tool names follow a consistent verb_noun pattern: list_printers, check_printability, optimize_orientation, analyze_model, get_print_quote, slice_model. No mixed conventions or vague verbs.
Six tools is a well-scoped set for a 3D printing MCP server, covering discovery, analysis, optimization, quoting, and slicing without bloat. Each tool addresses a distinct stage in the workflow.
The surface covers the full user journey from selecting a printer/material to running a DFM check, optimizing orientation, and obtaining a slicer-accurate quote or G-code. No critical missing operations; the paid tools have clear free/paid tiers handled via x_payment.
