Set up with your agent

Tell your agent which printer system you use (OctoPrint, Klipper, Bambu Lab, Prusa, and so on) and its address, if you know them, then copy and paste this:

text

Install mcp-3d-printer-server in the agent/harness I'm using now.

Read https://github.com/DMontgomery40/mcp-3D-printer-server/blob/main/docs/SETUP.md
for the current setup instructions and supported printer backends.

Detect my OS and harness, then use its native MCP configuration or installer.
Preserve my existing servers and settings. Prefer the published npm package
(npx -y mcp-3d-printer-server, stdio); use Node.js 24 if a runtime is needed.

Ask which printer system I use and set PRINTER_TYPE to match. Never guess it.
Then ask only for the values that backend needs:
- octoprint: PRINTER_HOST, PRINTER_PORT if not 80, API_KEY
- klipper (Moonraker): PRINTER_HOST, PRINTER_PORT (usually 7125)
- duet: PRINTER_HOST, PRINTER_PORT if not 80
- repetier: PRINTER_HOST, PRINTER_PORT (usually 3344), API_KEY
- bambu: PRINTER_HOST, BAMBU_SERIAL, BAMBU_TOKEN (the LAN access code),
  and BAMBU_MODEL
- prusa: PRINTER_HOST (PrusaLink address or connect.prusa3d.com), API_KEY
- creality: PRINTER_HOST, PRINTER_PORT if not 80, API_KEY (bearer token)
For Bambu Lab, confirm the exact printer model with me; never guess it, and
explain any LAN Only Mode or Developer Mode setting I need to enable.
Keep keys, tokens, and access codes in local/private configuration; do not
repeat them in chat.

Bambu Lab has the most hardware testing. The other backends use each
system's HTTP API and rely on community reports, so tell me plainly if a
backend does not respond as the guide describes.

Offer these optional extras, and set them up only if I choose them:
- Blender MCP for model edits: uvx mcp-for-blender (formerly blender-mcp,
  which now installs it as a compatibility wrapper). Its Blender addon must be
  installed, enabled, and connected inside Blender.
- A slicer for slice_stl: look for an installed PrusaSlicer, OrcaSlicer,
  FULU OrcaSlicer-bambulab, Bambu Studio, or CuraEngine before suggesting
  an install.
Configure executables in the server environment. Do not enable
MCP_ALLOW_EXECUTABLE_ARG. Leave print confirmation on: do not set
PRINT_REQUIRE_CONFIRMATION=0 or BAMBU_REQUIRE_CONFIRMATION=0 unless I ask
for a headless setup.

Verify that the MCP initializes, lists its tools, and reads printer status.
Do not start a print or change printer settings, including temperatures, as
a setup test. Tell me what worked and whether I need to restart or reload
the harness.
