Factor

Factor a polynomial over the rationals.

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

  "type": "object",
  "properties": {
    "expression": {
      "type": "string",
      "minLength": 1,
      "description": "Algebraic expression, e.g. '(x+1)^2'"
    }
  },
  "required": [
    "expression"
  ],
  "additionalProperties": false
}

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

Request

{
  "expression": "x^2 - 5*x + 6"
}

Response

{
  "ok": true,
  "result": {
    "result": "(-2+x)*(-3+x)"
  }
}

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

• Expression is not a polynomial in a single recognisable variable.
  Returns the input unchanged.
• 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`.
