Exact arithmetic: one calculator tool over an AST allowlist, with integers exact at any size.

Install

claude mcp add calc-mcp-server -- uvx calc-mcp-server

Our take

A narrowly scoped calculator server focused on exact arithmetic, using an AST allowlist and arbitrary-size integers rather than general code execution. It is most useful for agents that need deterministic math without floating-point drift or sandbox risk. Quality signals are limited: no visible adoption data and no package beyond PyPI, but the scope is clear and the safety model is a reasonable sign for such a small utility.
