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:

Question: What is 247 times 83?
Step 1: Model called multiply({"a": 247, "b": 83})
Step 2: Calculator result: 20501
Step 3: Final answer: The product of 247 and 83 is 20,501.

Works with Claude Desktop, Claude Code, or any MCP client. Zero dependencies (Python stdlib only).

See mcp/calculator/README.md for setup and usage.
