Overview

AI-generated overview

Remote browser-based CAD server that lets an assistant sketch, extrude, revolve, fillet, shell, assemble and export STEP or STL models.

What you can do
  • Create and edit 3D CAD geometry: sketch profiles, then extrude, revolve, fillet and shell them.
  • Combine parts into assemblies.
  • Export finished models as STEP or STL files.
  • No tool list is published, so the exact commands are only known after connecting.
When to use it
Useful when you want an assistant to build or modify parametric 3D models and hand back STEP or STL files, for example for mechanical parts or printable designs, without running CAD software locally.
Requirements
A remote MCP endpoint at protojoint.ai over streamable HTTP. OAuth sign-in is required. No environment variables or headers are declared.
Before you install
Access is tied to an OAuth account, so the assistant acts on your ProtoJoint workspace. Modeling operations change existing designs, and exports produce files you should review before using them for manufacturing.

Installation

In SourceWeft

  1. Open ProtoJoint in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.protojoint%2Fprotojoint/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

{
  "mcpServers": {
    "protojoint": {
      "type": "http",
      "url": "https://protojoint.ai/mcp"
    }
  }
}

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
