# MCP 3D Printer Server (MCP server) > MCP 3D Printer Server is an MCP server that connects MCP to major 3D printer APIs (Orca, FULU's Orca/Bambu, OctoPrint, Klipper, Duet, Repetier, Prusa, Creality). It has 245 GitHub stars, is released under the GPL-2.0 license and runs locally with npx -y mcp-3d-printer-server. Thank you, FULU Foundation, Louis Rossmann, and the OrcaSlicer-bambulab contributors. Thank you for standing up for consumer ownership, open-source developers, repair rights, and owners whose working hardware should not be made worse by locked-down software. This server treats the FULU OrcaSlicer-bambulab fork as a first-class slicer for Bambu Lab projects. See the FULU guide for setup and current status. ## Key facts | Fact | Value | |---|---| | Repository | https://github.com/DMontgomery40/mcp-3D-printer-server | | GitHub stars | 245 | | License | GPL-2.0 | | Language | TypeScript | | Transport | stdio | | Packages | npm: mcp-3d-printer-server | | Remote URL | none | | Needs API key | no | | Official | no | | Works with | Claude Desktop, Claude Code, Cursor, VS Code | | Category | Other | | Latest release | v1.2.11 (Oct 6, 2026) | | Last commit | Oct 6, 2026 | ## Install ### Claude Desktop (claude_desktop_config.json) ```json { "mcpServers": { "mcp-3d-printer-server": { "command": "npx", "args": [ "-y", "mcp-3d-printer-server" ] } } } ``` Settings > Developer > Edit Config. macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\.

Returns the bounding box, dimensions, center, vertex count, and face count. - `scale_stl`: Scale a model uniformly with scalefactor, or per axis with scalex, scaley, and scalez. - `rotate_stl`: Rotate a model around the X, Y, and Z axes, in degrees. Omitted axes default to 0. - `translate_stl`: Move a model along the X, Y, and Z axes, in millimeters. Omitted axes default to 0. - `extend_stl_base`: Add solid geometry underneath the model to raise and widen its base. - `merge_vertices`: Merge vertices closer together than tolerance (millimeters, default 0.01). - `center_model`: Move the model so the center of its bounding box is at the origin (0, 0, 0). - `lay_flat`: Find the model's largest flat face and rotate the model so that face rests on the XY plane (Z = 0). - `modify_stl_section`: Apply a scale, rotation, or translation to one section of a model: the top, bottom, or center third of its bounding… - `generate_stl_visualization`: Render an SVG with front, side, top, and isometric views of a model. - `get_printer_status`: Read the printer's current status. The response is the backend's own status data: Bambu returns temperatures, job… - `list_printer_files`: List the files stored on the printer or its host software. On Bambu printers it lists the cache/, timelapse/, and… - `upload_gcode`: Upload G-code to the printer, and optionally start it. Pass gcodepath for a local file, or gcode with the content (or… - `start_print`: Start a G-code file that is already stored on the printer. The server downloads that exact file, inspects it, checks… - `cancel_print`: Cancel the current print job. Cancelling is never gated and also cancels checked prints still waiting to start. - `set_printer_temperature`: Set a target temperature for a printer component. Use bed or extruder; Bambu also accepts nozzle, tool, and tool0. - `temperature`: must be a finite number of 0 or more. 0 switches the heater off and is never gated. - `print_3mf`: Upload a sliced .3mf project to a Bambu printer over FTPS and start it with an MQTT projectfile command that carries… - `ams_mapping`: is an object whose values are AMS slot numbers. When it is omitted, the mapping embedded in the 3MF is used; with no… - `nozzle_type`: sets the installed nozzle when the project must be auto-sliced. The job's nozzle type must match the printer's report. - `bed_type`: is one of texturedplate, coolplate, engineeringplate, or hotplate (default BEDTYPE, else texturedplate). - `nozzle_diameter`: accepts 0.2, 0.4, 0.6, or 0.8 (default NOZZLEDIAMETER or 0.4). - `layer_height`: , nozzletemperature, bedtemperature, and supportenabled are accepted but not applied: those settings are baked into… - `check_fulu_orca_setup`: Inspect a FULU OrcaSlicer-bambulab install: the executable, the platform runtime payload, the install and verify… - `fulu_bambu_network_rpc`: Call one FULU BambuNetwork bridge method for diagnostics. Read-only methods such as bridge.handshake,… - `slice_stl`: Slice an STL or 3MF with the configured slicer and return the output path: G-code for PrusaSlicer, Slic3r, generic… - `slicer_profile`: is a process profile only. A machine;process list is rejected with instructions. - `load_filaments`: Filament profile JSON paths in slot order, ;-separated. One profile applies to every slot; otherwise give one per… - `load_filament_ids`: Comma-separated filament IDs mapping filaments to objects, such as 1,2,3,1 - `filament_colours`: One #RRGGBB per filament slot, ;-separated. Defaults to the input 3MF's colours, then each profile's colour - `slice_with_template`: Slice an STL or 3MF with a named template from the local template registry. - `list_templates`: List the saved slicing templates (.3mf, .json, .config) in the registry directory, BAMBUTEMPLATEDIR (default… - `save_template`: Copy a local .3mf, .json, or .config file into the template registry. - `get_slice_settings`: Read the slicer settings in a 3MF, an extracted projectsettings.config, or a profile JSON without slicing: layer… - `confirm_temperatures`: Report every heater target in a G-code file: S and R forms, tool-addressed targets, RepRapFirmware G10/M568, and… - `process_and_print_stl`: Extend an STL's base, slice it, and print it through the same checked print gate as uploadgcode and print3mf,… - `blender_mcp_status`: Inspect the Blender MCP configuration. With connect: true, it starts the configured server, initializes it, and lists… - `blender_mcp_call`: Call a tool the Blender MCP server advertises, such as getsceneinfo or executeblendercode, with arguments matching its… - `blender_mcp_export_stl`: Export named objects from the live Blender scene to a new STL for slicing. - `output_path`: must be new and its parent must exist; nothing is ever overwritten. ## Similar MCP servers - [Reactive Resume](https://appsgit.com/mcp-servers/reactive-resume): A one-of-a-kind resume builder that keeps your privacy in mind.
