Summary
This server exposes symbolic regression through two tools: sindy_run for discovering differential equations from time series data in seconds, and pysr_run for finding algebraic relationships via evolutionary search that returns a Pareto front of expressions ranked by complexity versus accuracy. It wraps PySINDy and SymbolicRegression.jl under the hood. You'd reach for this when you have numerical measurements and want governing equations instead of black box models. The free tier handles up to 100 rows and 8 variables, then switches to pay per use via x402 or card. Connects over streamable HTTP to occam.fit/mcp/ and includes a bootstrap uncertainty tool for getting confidence intervals on fitted constants.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.
