RocketSmith

Let agents design, simulate, and build your rocket.

RocketSmith is an end-to-end model-rocket toolchain exposed as an MCP extension. It orchestrates OpenRocket (flight simulation), build123d (parametric CAD), and PrusaSlicer (FDM slicing) behind a single agent, and closes the loop by feeding real printed-part weights back into the simulation for post-build stability verification.

Install

Claude Code (plugin)

Prerequisites: Create a GitHub SSH key and add it to your account before proceeding — see Generating a new SSH key.

Inside a Claude Code session, add the marketplace and install the plugin:

/plugin marketplace add ppak10/RocketSmith

/plugin install rocketsmith@rocketsmith

After installing, reload plugins and verify the MCP server is connected with /reload-plugins and /mcp

Gemini CLI (extension)

gemini extensions install https://github.com/ppak10/RocketSmith

Requirements

• Java runtime — required by OpenRocket
• OpenRocket 23.09 — uses orhelper, which targets the net.sf.openrocket package in OpenRocket 23.09 and earlier. OpenRocket 24+ is not supported.
• PrusaSlicer (optional — needed for the full CAD → print → mass calibration loop)

See Installation for platform-specific setup and troubleshooting.
