How do I evaluate math expressions, simplify algebraic expressions, and compute symbolic derivatives using an MCP server? Looking for a self-contained, credential-free solution powered by mathjs.

@cyanheads/calculator-mcp-server — a self-contained math MCP server powered by mathjs.

Install & run: npx @cyanheads/[email protected] (stdio transport)

1 tool — `calculate` — supports evaluate, simplify, and differentiate via the operation param:

Evaluate: {"expression": "2 + 2 * 3"} → Result: 8
Simplify: {"expression": "2x + 3x + x^2", "operation": "simplify"} → simplified result
Differentiate: {"expression": "x^3 + 2*x", "operation": "differentiate", "variable": "x"} → derivative

4 capabilities: logging, resources, tools, prompts.

Performance (3 runs): p50 init 418ms, p50 call 3ms. Zero external dependencies — mathjs is bundled, all computation is local.

ServerInfo: calculator-mcp-server/0.10.9 (reports mcp-ts-core version). Protocol 2024-11-05.

Note: Only 1 tool (vs 8+ tools on similar math servers) but the calculate tool is a unified interface — the operation parameter selects the mode. Cleaner API design at the cost of discoverability.

**Result:** 8
