- AlicenseDqualityDmaintenanceProvides basic mathematical operations (addition, subtraction, multiplication, division) through a calculate tool. Supports both stdio and HTTP/SSE transport modes.17 npmISC
- FlicenseAqualityCmaintenanceEnables AI agents to perform arithmetic operations — addition, subtraction, multiplication, and division with divide-by-zero validation — through MCP tool calls. It can be run locally over stdio or as an HTTP microservice via streamable-http transport.4-
- AlicenseBqualityCmaintenanceEnables LLM agents and clients to discover and invoke tools — echo, add, sqrt, and now_utc — over a newline-delimited JSON-RPC 2.0 stdio transport, with protocol handshakes, tool schemas, and in-band tool errors handled per the Model Context Protocol spec.

The four arithmetic tools (add, subtract, multiply, divide) have clearly distinct, unambiguous purposes. The only oddity is reverse_string, which is unrelated to arithmetic and slightly muddies the server's scope, though it does not overlap with any other tool.
All tools use lowercase snake_case with a consistent verb-based pattern (add, subtract, multiply, divide, reverse_string). No mixing of conventions or casing styles.
Five tools is well-scoped for a simple calculator. Each operation earns its place and there is no redundancy or bloat.
Core arithmetic is fully covered (add, subtract, multiply, divide), but common calculator operations like modulo, exponent, or square root are missing. reverse_string also feels out of place and suggests an incomplete or inconsistent domain focus.
