Integrate

Indefinite symbolic integration. The constant of integration is omitted.

Validated server-side with Zod. The same schema feeds OpenAPI and the MCP tool list.

All tools return { ok: true, result } on success and { ok: false, error } on failure. The result object contains:

Request

{
  "expression": "x * sin(x)",
  "variable": "x"
}

Response

{
  "ok": true,
  "result": {
    "result": "-cos(x)*x+sin(x)"
  }
}

MCP clients call this tool as tools/call against /api/mcp:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "integrate",

      "expression": "x * sin(x)",
      "variable": "x"
    }
  }
}

• Integrand has no elementary antiderivative.
  Nerdamer returns an unevaluated `integrate(…)` placeholder.

  {
    "expression": "exp(-x^2)",
    "variable": "x"
  }

• A required field is missing or has the wrong type.
  Zod validation error, e.g. `Required` or `Expected string, received number`.
• Nerdamer cannot parse the expression (unbalanced parens, unknown function, stray characters).
  `Unexpected token …` or `… is not a valid expression`.
