How do I use spoolman-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@spoolman-mcp How much PLA do I have left?" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

🧵 Spoolman MCP Server

Version License: MIT TypeScript MCP Spoolman

A Model Context Protocol server for Spoolman — manage your entire 3D printer filament inventory through natural language with Claude and other AI assistants! 🎉

🚀 What is this?

This MCP server bridges the gap between AI assistants (like Claude) and your self-hosted Spoolman instance. Instead of clicking through the Spoolman UI, you can simply ask your AI assistant:

"How much PLA do I have left?" "Add a new Bambu Lab PETG spool, 1kg, red." "Mark spool #12 as used by 50g."

The server exposes the full Spoolman REST API v1 as MCP tools — every vendor, filament, spool, setting, custom field, lookup, and export endpoint is covered.

✨ Features

🏭 Vendor Management — Create, read, update, delete vendors
🎨 Filament Management — Full CRUD with color, temperature settings, article numbers
🧵 Spool Management — Track spools, log usage (by weight or length), weight measurement, archiving
⚙️ Settings — Read and write Spoolman configuration
🏷️ Custom Fields — Manage extra fields for vendors, filaments, and spools
🔍 Lookups — Browse all materials, locations, lot numbers, article numbers
📦 Export — Export data as JSON or CSV
💓 System — Health check, info, and backup trigger

NOTE

This server communicates with yourlocal/self-hosted Spoolman instance. You need a running Spoolman before using this MCP server.

💬 Example Conversations

Once connected, you can have natural conversations like:

You: How many spools do I currently have?

Claude: You have 14 spools in Spoolman. 3 of them are archived.
        The active spools include 5x PLA, 4x PETG, and 2x ABS.

You: Add a new Bambu Lab PLA Basic spool. It's red, 1kg, 1.75mm.

Claude: I'll create that for you right away!
        ✅ Spool created: Bambu Lab PLA Basic (Red) — 1000g remaining.

You: I just printed something and used about 45g from spool #7.

Claude: Done! Spool #7 now has 623g remaining (was 668g).

You: I just weighed spool #3 on my kitchen scale — it's 312g total.

Claude: Got it! Based on the empty spool weight of 190g, spool #3
        now shows 122g of filament remaining.
