Bambu Project QA MCP

Local MCP tools for inspecting Bambu Studio projects before printing. This is intentionally a project QA and preparation server, not a full printer-control server.

Tools

• inspect_model: inspect a .stl or .3mf.

• inspect_3mf_project: validate a Bambu Studio .3mf and report risky support/slicer settings.

• create_leg_safe_support_variant: create a .3mf copy with easier-removal support settings for delicate horse legs/details.

• open_in_bambu_studio: open a file in Bambu Studio on this Windows machine.

Safety Limits

• This server does not start prints.

• It does not handle Bambu LAN access codes, printer serial numbers, MQTT, or FTPS.

• It does not auto-paint support blockers. Bambu support painting metadata is not documented and was not present in the inspected local projects.

• It validates 3MF ZIP paths so generated files use forward slashes and open correctly in Bambu Studio.

Run Tests

npm.cmd test

MCP Configuration

Use a local stdio server:

{
  "mcpServers": {
    "bambu-project-qa": {
      "type": "stdio",
      "command": "node",
      "args": [
        "/path/to/bambu-project-qa-mcp/bin/bambu-project-qa-mcp.js"
      ],
      "env": {}
    }
  }
}

Example Tool Inputs

Inspect a project:

{
  "path": "/path/to/models/horses_frame_4in_P2S.3mf"
}

Create a leg-safe support variant:

{
  "inputPath": "/path/to/models/horses_frame_4in_P2S.3mf",
  "outputPath": "/path/to/models/horses_frame_4in_leg_safe_P2S.3mf"
}
