What is an MCP calculator for Claude?

MCP (Model Context Protocol) lets Claude call external tools like precise calculators for mortgages, BMI, or compound interest — deterministic, no hallucinations.

How do I install mcp-calculators in Cursor?

Add the JSON config to your Cursor MCP file (OS-specific path), run npx @thicket-team/mcp-calculators, restart. Ask Cursor to list tools.

Will MCP replace built-in AI math?

Not yet — it augments with cited, exact formulas where models falter, especially finance and science.
