Free 3D conversion (FBX, GLB, OBJ, STL, PLY, DAE, USDZ, 3MF) as a remote MCP server. No account.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP

What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

  • list_tools

    The conversions this server offers: for each, the job kind, the accepted source extensions, the target (a format name, or the kind itself for a mesh tool), the upload cap in MB, whether a zip is accepted, and the page where the same conversion runs in a browser.

  • conversion_notes

    Before uploading anything: for a pair of formats (for example from "fbx" to "glb"), what survives the trip (skeleton, shape keys, materials, vertex colours), what is lost, the known limits of the two formats, and the page for that pair. Says so when the pair is not offered and na

  • convert_file

    Starts a conversion. Give the target (`to`: a format name such as glb, fbx, obj, stl, ply, dae, usdz, 3mf, or a mesh tool kind from list_tools such as mesh-decimate) and the file as an https link (`file_url`) or as the file attached to the chat (`file`). The source format is read

  • job_status

    The state of a conversion started by convert_file: queued, processing, ready, failed (with the reason), expired, or refused when the file needs a choice only the page can offer.

  • result_link

    For a ready conversion: the download link (valid 3 days, no sign-in), the file name, the expiry date, and a link that opens the result in a viewer on the site.

Common questions

Is Shapeweld safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Shapeweld MCP server

A 3D converter your agent can call. Shapeweld's free converters are also a remote MCP server: point an agent at one URL and it can ask what a conversion keeps, hand over a file, wait for it and give you the download link.

This repository holds the server's registry manifest (server.json) and this guide. The server itself runs at shapeweld.com; there is nothing to install.

The endpoint

https://shapeweld.com/mcp

Streamable HTTP, no sign-in, no key. The server is the same converter the pages use, with the same limits and the same 3-day retention.

Connecting

Claude

  1. Open Settings → Connectors.
  2. Choose Add custom connector.
  3. Paste https://shapeweld.com/mcp and save.
  4. Ask Claude to convert a file you attached or linked.

ChatGPT

ChatGPT lists MCP servers through its directory; Shapeweld is submitted and will appear there once accepted. Until then the server works in any client that takes a URL.

Cursor and other clients

Cursor, Windsurf, VS Code and most agent frameworks take a remote MCP server by URL in their MCP settings: add https://shapeweld.com/mcp as a streamable-http server. No command, no environment variables.

{

"mcpServers": { "shapeweld": { "type": "streamable-http", "url": "https://shapeweld.com/mcp" } } }

The five tools

ToolWhat it doesInput
list_toolsLists the conversions on offer with the accepted extensions and size caps.none
conversion_notesSays what a pair keeps and what it drops before you upload anything.from, to
convert_fileDownloads your file from a link, or takes the file you attached in ChatGPT, and starts the conversion.to, file_url or file, from for a zip, options
job_statusQueued, processing, ready, failed, or refused with the reason.jobId
result_linkThe download link, the file name, the expiry date and a viewer link.jobId

Formats: GLB, FBX, OBJ, Blender (.blend), STL, PLY, DAE, USDZ and 3MF, in the pairs listed by list_tools; plus the mesh tools (compress-glb, mesh-decimate, mesh-lod, mesh-repair, mesh-unwrap, svg-to-3d), addressed by their kind in to.

Limits

Per session: 10 conversions an hour and 40 a day. Across all agents: 200 a day. Files follow the page's cap: 100 MB for the GLB, FBX, OBJ and Blender pairs and the compressor, 50 MB for the rest, 5 MB for an SVG. Only https links are fetched.

When a limit is reached the tool says so and gives the page URL, where the same conversion runs in the browser.

What we receive and keep

We receive the file the agent fetched for you and the agent's name (Claude, ChatGPT, Cursor or other). We keep the upload and the result for 3 days, then delete both. We never receive your conversation. Results are handed out through a signed link that works without a cookie for those 3 days. Privacy: https://shapeweld.com/privacy

Domain verification

When the server is submitted to the ChatGPT directory, the challenge file is served from the site at https://shapeweld.com/.well-known/openai-apps-challenge; it is not part of this repository.
