Summary
Brings NumPy's entire numerical computing toolkit into Claude through MCP. You get all the essentials: array creation (zeros, ones, arange, linspace), manipulation (reshape, transpose, concatenate), mathematical operations (sum, mean, dot, matmul), linear algebra (inv, det, eig, svd), and random number generation. Also exposes element-wise operations like trig functions, logarithms, and arithmetic, plus statistics tools like percentile, histogram, and correlation. Install via pip, add the command to your MCP config, and you can start running matrix operations, solving linear systems, or computing eigenvalues without spinning up a separate Python environment. Solid choice when you need numerical computation without leaving your Claude workflow.
