Calculator MCP

A community-built Model Context Protocol server providing exact arithmetic capabilities via a single 'calculate' tool. It evaluates mathematical expressions against a hand-rolled AST allowlist to ensure safety, avoiding unbounded dependencies or eval() usage. It supports integers of any size, standard operators, constants like pi and e, and various mathematical functions, ensuring precise results without floating-point errors for large numbers.
