MathKernel Ships an MCP Server Exposing 162+ Math Tools Across SymPy, Z3, Lean and mpmath With Per-Claim Provenance
Created 2026-09-06 and at 42 stars, MathKernel is an evidence-aware mathematics runtime whose stated split is 'The LLM interprets intent; the MathKernel establishes mathematical evidence.' It orchestrates SymPy for symbolic work, mpmath for arbitrary-precision and interval arithmetic, Z3 for SMT solving, Lean for formal proof, SciPy, NumPy/CuPy and Numba behind one typed MathIR, and speaks MCP over stdio with 162+ `math_`-prefixed tools including `math_parse`, `math_solve`, `math_reason` and `math_derivation_trace`. The interesting design choice for builders is that it carries trust labels and assumption provenance per claim rather than returning a bare number.
