Infinity-API

Capabilities

• Performs rocket simulations and returns simulation data
• Stores simulation input data in mongo-db

Setup

• Install python3 3.11.5 or above
• install mongodb-atlas
• Install dependencies python3 -m pip install -r requirements.txt

Development

• make format
• make test
• make clean
• make build

Starting the server

• Setup MONGODB_CONNECTION_STRING:

$ touch .env && echo MONGODB_CONNECTION_STRING="$ConnectionString" > .env

Docker

• run docker compose: docker-compose up --build -d

Standalone

• Dev: python3 -m uvicorn src:app --reload --port 3000
• Prod: gunicorn -k uvicorn.workers.UvicornWorker src:app -b 0.0.0.0:3000

MCP Server

• The MCP bridge is mounted directly on the FastAPI app and is available at /mcp alongside the REST API.
• No extra process is required: uvicorn src:app serves both the REST routes and the MCP transport.
