engineer.calc/calc MCP server
89 tools · tools last listed 4 Nov 2026
A community server in the official MCP registry. Once a day, Stackduke's Radar connects to it the way any MCP client would, with no account and no sign-in, and lists its tools. It never runs them.

Labels for community servers are machine guesses from each server's own tool names, descriptions and hints (accuracy not yet measured). They are not a safety verdict. How labels work
