300+ calculators for AI agents via the Model Context Protocol. MCPCalc is a hosted MCP server that gives AI agents (Claude, ChatGPT, and others) access to a comprehensive library of calculators spanning finance, math, health, construction, engineering, food, automotive, and more
Overview
What is MCPCalc?
MCPCalc is a remote MCP server that provides AI agents access to a hosted computational platform with over 300 calculators, a Computer Algebra System (CAS), and a spreadsheet engine. There is nothing to install — AI agents connect directly to the hosted endpoint.
How to use MCPCalc?
Connect any MCP client (Claude Desktop, Cursor, etc.) by adding the URL https://mcpcalc.com/api/v1/mcp to the client configuration. No API key or authentication is required. For Claude.ai, search for "MCPCalc" in the MCP integrations menu. The agent usage guide is available at mcpcalc.com/api/v1/mcp/guide.
Key features of MCPCalc
- 300+ form calculators across 15 categories (finance, math, health, construction, etc.)
- Full Computer Algebra System (CAS) for symbolic algebra, calculus, and equation solving
- Interactive spreadsheet engine with cell formulas, CSV import/export, and range operations
- Session-based computation with state persistence and prefilled URL generation
- Streamable HTTP transport — no local installation, API keys, or environment variables required
Use cases of MCPCalc
- Run financial calculations (mortgage payments, compound interest, retirement planning)

- Execute and share interactive spreadsheet calculations via MCP sessions
FAQ from MCPCalc
Do I need to install anything to use MCPCalc?
No. MCPCalc is a fully hosted service. AI agents connect directly via Streamable HTTP at https://mcpcalc.com/api/v1/mcp — no local installation is required.
Is an API key or authentication required?
No API key or authentication is required to connect to MCPCalc.
What types of tools does MCPCalc expose?
MCPCalc exposes tools to list calculators, get calculator schemas, run calculations, generate prefilled URLs, and manage interactive sessions (create, get state, push actions, close).
Can I do symbolic math with MCPCalc?
Yes. The cas calculator supports symbolic algebra, calculus (derivatives, integrals, limits), equation solving, interactive plotting, LaTeX input, and variable assignment.
Does MCPCalc have spreadsheet capabilities?
Yes. The spreadsheet calculator provides a grid-based environment with cell formulas, A1 range operations, CSV import/export, column formatting, and full session state access.
