Install

How do I install the SimplyPrint: 3D Print Farm Management MCP server?

SimplyPrint: 3D Print Farm Management is a hosted endpoint at https://simplyprint.io/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the SimplyPrint: 3D Print Farm Management MCP server?

SimplyPrint: 3D Print Farm Management is an MCP server listed in the public MCP registry as io.simplyprint/simplyprint. 3D print farm management for AI. Monitor, queue, and control prints on your SimplyPrint account. This page covers its hosted endpoint (https://simplyprint.io/api/mcp).

Is the SimplyPrint: 3D Print Farm Management MCP server safe to use?

SimplyPrint: 3D Print Farm Management scores 89 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the SimplyPrint: 3D Print Farm Management MCP server expose?

SimplyPrint: 3D Print Farm Management exposes 75 tools: list_printers, get_printer, get_farm_overview, pause_print, resume_print, and 70 more. Their descriptions and schemas cost roughly 7,851 tokens of context every time the server is loaded.

Does the SimplyPrint: 3D Print Farm Management MCP server require authentication?

Yes. SimplyPrint: 3D Print Farm Management asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the SimplyPrint: 3D Print Farm Management MCP server still maintained?

SimplyPrint: 3D Print Farm Management is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
