Calculator

Exposes addition, subtraction, multiplication, and division operations through the Model Context Protocol (MCP) as callable tools. Implements stateless arithmetic evaluation by registering discrete tool handlers that accept numeric operands and return computed results, enabling LLM agents and applications to invoke math operations as first-class functions within MCP-compliant environments without embedding calculation logic directly in prompts.

Processes mathematical expressions containing multiple operands and operators (e.g., '5 + 3 * 2') by parsing the input string and evaluating according to standard operator precedence rules. The implementation likely uses a simple expression parser or evaluator that respects mathematical order of operations (multiplication/division before addition/subtraction) and returns the computed scalar result, enabling users to submit complex calculations in natural mathematical notation rather than requiring sequential single-operation tool calls.

Implements error detection and reporting for invalid arithmetic operations such as division by zero, non-numeric operands, or malformed expressions. The capability returns structured error messages or exceptions that indicate the type of failure (e.g., 'DivisionByZeroError', 'InvalidOperandType') and potentially the problematic input, allowing downstream applications and LLM agents to handle failures gracefully rather than silently returning incorrect results or crashing.

Executes arithmetic operations synchronously with minimal overhead, returning results immediately without queuing, async processing, or external service calls. The MCP server processes each calculation request in-process, avoiding network round-trips or I/O delays beyond the initial MCP protocol handshake.
