Implementation Reference
- src/index.ts:386-426 (handler)Core implementation of the generate_random_float tool handler. Uses crypto.randomBytes for secure randomness, scales to [min, max), applies precision rounding, generates multiple values if specified, and returns structured JSON response.
private async generateRandomFloat(args: any) { const min = args.min ?? 0.0; const max = args.max ?? 1.0; const count = args.count ?? 1; const precision = args.precision ?? 6; if (min >= max) { throw new Error("Minimum value must be less than maximum value"); } if (count < 1 || count > 1000) { throw new Error("Count must be between 1 and 1000"); } if (precision < 1 || precision > 15) { throw new Error("Precision must be between 1 and 15"); } const results: number[] = []; for (let i = 0; i < count; i++) { // Generate cryptographically secure random float const randomBuffer = randomBytes(4); const randomValue = randomBuffer.readUInt32BE(0) / 0xFFFFFFFF; const scaledValue = min + (randomValue * (max - min)); results.push(parseFloat(scaledValue.toFixed(precision))); } return { content: [ { type: "text", text: JSON.stringify({ type: "random_floats", values: results, parameters: { min, max, count, precision }, timestamp: new Date().toISOString(), }, null, 2), }, ], }; } - src/index.ts:79-108 (schema)Input schema for generate_random_float tool defining parameters: min (number, default 0.0), max (number, default 1.0 exclusive), count (1-1000, default 1), precision (1-15 decimals, default 6).
