Rupa3D runs on your own machine — the client starts it, so there is no endpoint to ping. 193 installs a week from npm. Last commit 15 Sep 2026.
Checks GLB assets against a spec without Blender and embeds the measured proof inside the GLB.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
const jalur = (a.env && process.env[a.env]) || path.join(REPO, a.jalur);
keluar = await this.#spawn([
exec(compile(t["kode"], "<rupa_skrip>", "exec"), ruang_nama)
el('pilih-isi').innerHTML = baris
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This one needs environment variables set before it will start:
RUPA3D_BLENDER (Path to the Blender executable. Only the Blender-backed tools need it; GLB checking, CAD and scenes run without Blender.), RUPA3D_RUANG (Workspace directory for scenes and CAD shapes. Default: ~/.rupa3d).
The author declared them in the registry entry; get the values from the project itself.
Checks .NET solutions against a fluent C# architecture spec and explains the rules to agents.
Checks the context files a coding agent reads against the git index, and reports what drifted.
Compile code with thousands of compilers, inspect the assembly, and share godbolt.org links
In-flight WiFi: provider by flight, airline or tail, measured speeds, Starlink rollout.
Call the real API and check the response against your OpenAPI spec.
Compile OpenSCAD, read computed values, preview and measure the mesh, without a GUI.
MCP proxy that checks every tools/call against Agent Trust policy, with evidence, before it runs.
Scan agent readiness, or find measured providers an unattended AI agent can finish with.
