# bbn-mcp-server

> bbn-mcp-server — nesar-bbn-mcp-server. Use this tool when you need to perform Big Bang Nucleosynthesis computations and analysis, solving problems related to cosmological parameter estimation and abundance fitting. It takes inputs such as baryon density, extra relativistic species, and neutron lifetime, and outputs fitted abundances against observational data. This tool is ideal for use cases requiring precise calculations of primordial element abundances and cosmological parameter scans.
