Calculator MCP Server
MCPOfficialOpen SourceMIT31.4
by wrtnlabs • Testing & QA
A lightweight MCP server that exposes basic calculator operations for LLMs and test integrations.
Example Use Cases
- 1
Perform and verify basic arithmetic operations (add, sub, mul, div, mod, sqrt) within a controlled MCP environment.
- 2
A lightweight test server to validate MCP client integrations and transport configurations (SSE, InMemoryTransport).
- 3
Run simple calculator-based automations inside IDE workflows (e.g., VS Code Copilot) or automated testing setups.
Description
Calculator MCP Server is a small Model Context Protocol server that lets LLMs and agents perform basic arithmetic (add, sub, mul, div, mod, sqrt) and simple automation tasks. It can be run via npx, supports SSE transport for remote connections, and can be embedded programmatically using createServer and InMemoryTransport. It's primarily aimed at testing MCP client integrations, toy projects, and IDE workflows (e.g., use with VS Code Copilot).
