Rocket Tools — Aerospace Engineering Intelligence
A dual-interface aerospace computation engine with 11 engineering tools, MCP server for AI agents, natural language router, and YAML workflow engine. Open source under Apache 2.0.

The Challenge
Aerospace calculations are scattered across textbooks, MATLAB scripts, and online calculators. Engineers waste time re-deriving basic formulas and verifying unit conversions.
AI agents that assist with engineering tasks lack access to structured, tested tools. They hallucinate formulas, confuse units, and produce unverifiable results.
Design reviews require chaining multiple calculations — structural loads feed into material selection, which feeds into aerodynamic analysis. Existing tools are siloed and do not compose.
Our Approach
We designed 11 precision tools covering the full aerospace engineering stack: beam analysis, material lookup, ISA atmosphere, and 7 aerodynamic calculators. Every tool is tested against reference values with 94 unit tests and 18 benchmarks.
We exposed the toolset as an MCP (Model Context Protocol) server, enabling AI agents to call verified engineering functions with structured inputs and outputs. No more hallucinated formulas.
The natural language router translates plain-english questions into precise tool calls. Ask 'What is the Reynolds number at 5 km and 250 m/s?' and get a verified answer with full working.
The YAML workflow engine chains tools into multi-step design reviews. A single file can run structural → materials → aerodynamic analysis and produce a unified report.
