MechanoFab MCP server

• Registry namecom.mechanofab/mechanofabverified in the MCP registry

The registry name sits under mechanofab.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 249 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• calculate_part_mass

  Use when the user provides a part volume and material to calculate mass or weight. Returns mass in grams and kilograms. Example: 'How heavy is a 100cm³ aluminum 6061 part?'

• check_equipment_capability

  Use when the user asks 'can the Bambu X1C print a 400mm × 400mm × 400mm part?', 'does this machine support 25 micron layer thickness?', 'is this machine capable for this part?'. Returns capable/not-capable with specific gaps.

• check_material_environment_compatibility

  Use when the user describes an operating environment (temperature, humidity, UV, chemicals) and wants to know if a material is suitable. Returns a compatibility rating (excellent/good/fair/poor) and specific risk factors.

• check_service_temperature

  Use when the user specifies an operating temperature and asks if a material is suitable (e.g. 'can ABS handle 80°C?', 'what is the max temp for 6061 aluminum?'). Returns within_range status, min/max service temps, and safety margin.

• compare_equipment

  Use when the user wants to compare specific machines (e.g. 'compare Formlabs Form 3 vs Stratasys J55', 'which machine has better build volume?'). Accepts 2–4 model IDs and optional metric list.

• compare_materials

  Use when the user asks to compare materials (e.g. 'AL6061 vs SS304', 'which plastic is stronger'). Returns a structured comparison table grouped by property. Accepts 2–5 material IDs and an optional list of properties to compare.

• compare_processes

  Use when the user wants to compare manufacturing processes (e.g. 'SLS vs FDM vs SLA comparison', 'which process has better tolerance: CNC or injection molding?'). Accepts 2–5 process IDs and optional metric list.

• filter_materials_by_constraint

  Use when the user specifies material requirements (e.g. 'density < 3 g/cm³', 'tensile > 400 MPa', 'max temp ≥ 200°C'). Returns all materials that pass every constraint. Supports gte, lte, eq, contains operators.

• find_alternative_processes

  Use when the user asks 'what can replace FDM for this part?', 'alternative to CNC for low volumes?', or needs to switch process due to lead time / cost / material constraints.

• find_equipment_by_process

  Use when the user asks 'what machines can do SLS?', 'do you have equipment that can print 300mm × 300mm?', 'which printers support PEEK material?'. Returns matching equipment with build volumes, layer thickness, and availability status.

• find_equivalent_materials

  Use when the user wants alternatives to a specific material (e.g. 'what can replace SS304?', 'cheaper alternative to titanium'). Returns materials ranked by similarity score. Match criteria include strength, density, cost_tier…

• get_equipment_qc_specs

  Use when the user asks about machine certifications, dimensional accuracy, or QC procedures (e.g. 'is this machine ISO certified?', 'what is the dimensional accuracy of the EOS M 290?', 'what inspection methods do you use for this…

• get_industry_requirements

  Use when the user asks industry-specific requirements (e.g. 'what materials are used in aerospace?', 'what certifications does the medical device industry require?', 'typical tolerances for automotive parts?').

• get_iso2768_tolerances

  Use when the user asks about ISO 2768 tolerances (e.g. 'what is ISO 2768-m tolerance for 50mm?', 'ISO 2768 fine grade flatness?', 'general tolerance for machined parts'). Returns the ±tolerance value, range string, and applicable…

• get_material_compliance

  Use when the user needs to know if a material meets regulatory requirements (e.g. 'is this plastic RoHS compliant?', 'does this aluminum meet FDA requirements?'). Returns compliance status for RoHS, REACH, FDA, ISO, ASTM, CE.

• get_material_process_compatibility

  Use when the user asks which processes can be used with a material (e.g. 'can titanium be FDM printed?', 'what processes work with PEEK?'). Returns compatible and incompatible process lists.

• get_process_specs

  Use when the user asks about process specs, capabilities, or constraints (e.g. 'what is the tolerance of SLS?', 'what is the build volume of FDM?', 'what lead time for CNC machining?'). Returns category, build size, tolerance, compatible…

• match_industry_materials

  Use when the user asks 'what materials are approved for medical devices?', 'best lightweight materials for aerospace?', 'food-safe materials for injection molding?'. Cross-references industries and materials dictionaries.

• quote_calc

  Use this tool to CALCULATE a 3D printing price. Provide material_name, color, lead_time (must match the 3dp-pricing dictionary), quantity, and either weight_g or volume_cm3 — or an uploaded file_key (obtained from /v1/uploads/presign +…

• search_materials

  Use to resolve a user's material description (industry grade name like 'PA12', a colloquial term like 'nylon', a Chinese term, or a vague description) into concrete materials.csv entries. Unlike compare_materials/find_equivalent_materials…
