Nanocalcs

Overview

Nanocalcs is a Model Context Protocol server that provides exact calculators for loans, dates, units, LLM tokens, API costs, and VRAM, with prefilled links to nanocalcs.com. Any MCP-compatible AI assistant can invoke these tools directly, letting the model decide when calculations are needed during conversations or agent workflows.

The server runs locally via the npm package nanocalcs-mcp, which communicates over stdio without requiring any credentials or setup. Install it with npx -y nanocalcs-mcp and it works immediately. The latest release is v0.2.1, and the project is available at https://nanocalcs.com.

Nanocalcs appears in the AI & Agents category on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed.
