MCP Calculator Server
New: mcp/calculator/ - a standards-compliant Model Context Protocol server that gives Apple Intelligence the ability to do math.
The #1 complaint from the HN thread: "the model can't calculate." This fixes that.
Seven math tools via MCP stdio transport: add, subtract, multiply, divide, sqrt, power, round_number.
Full round-trip proven:
