## Installation
```bash
npm install mcp-rand
```
Or install globally:
```bash
npm install -g mcp-rand
```
## Features
### UUID Generator
- Generates RFC 4122 version 4 UUIDs
- Uses Node's native crypto module for secure random generation
- No parameters required
### Random Number Generator
- Generates random numbers within a specified range
- Configurable minimum and maximum values (inclusive)
- Defaults to range 0-100 if no parameters provided
### Gaussian Random Generator
- Generates random numbers following a Gaussian (normal) distribution
- Normalized to range 0-1
- No parameters required
### Random String Generator
- Generates random strings with configurable length and character sets
- Supports multiple character sets:
* alphanumeric (default): A-Z, a-z, 0-9
* numeric: 0-9
* lowercase: a-z
* uppercase: A-Z
* special: !@#$%^&*()_+-=[]{};\'"\\|,.<>/?
- Configurable string length (defaults to 10)
### Password Generator
- Generates strong passwords with a mix of character types
- Ensures at least one character from each type (uppercase, lowercase, numbers, special)
- Configurable length (minimum 8, default 16)
- WARNING: While passwords are generated locally, it's recommended to use a dedicated password manager
### Dice Roller
- Roll multiple dice using standard dice notation
- Supports notation like "2d6" (two six-sided dice), "1d20" (one twenty-sided die)
- Returns individual rolls and total for each set of dice
- Can roll multiple different dice sets at once (e.g., "2d6", "1d20", "4d4")
### Card Drawer
- Draw cards from a standard 52-card deck
- Maintains deck state between draws using base64 encoding
- Returns drawn cards and remaining deck state
- Supports drawing any number of cards up to the deck size
- Properly shuffles available cards before each draw
## Usage
### As a CLI Tool
```bash
npx mcp-rand
```
### Integration with MCP Clients
Add to your MCP client configuration:
```json
{
"mcpServers": {
"mcp-rand": {
"command": "node",
"args": ["path/to/mcp-rand/build/index.js"],
"disabled": false,
"alwaysAllow": []
}
}
}
```
### Example Usage
```typescript
// Generate UUID
const uuid = await client.callTool('generate_uuid', {});
console.log(uuid); // e.g., "550e8400-e29b-41d4-a716-446655440000"
// Generate random number
const number = await client.callTool('generate_random_number', {
min: 1,
max: 100
});
console.log(number); // e.g., 42
// Generate Gaussian random number
const gaussian = await client.callTool('generate_gaussian', {});
console.log(gaussian); // e.g., 0.6827
// Generate random string
const string = await client.callTool('generate_string', {
length: 15,
charset: 'alphanumeric'
});
console.log(string); // e.g., "aB9cD8eF7gH6iJ5"
// Generate password
const password = await client.callTool('generate_password', {
length: 20
});
console.log(password); // e.g., "aB9#cD8$eF7@gH6*iJ5"
// Roll dice
const rolls = await client.callTool('roll_dice', {
dice: ['2d6', '1d20', '4d4']
});
console.log(rolls);
/* Output example:
[
{
"dice": "2d6",
"rolls": [3, 1],
"total": 4
},
{
"dice": "1d20",
"rolls": [4],
"total": 4
},
{
"dice": "4d4",
"rolls": [2, 3, 2, 3],
"total": 10
}
]
*/
// Draw cards
const draw1 = await client.callTool('draw_cards', {
count: 5
});
console.log(draw1);
/* Output example:
{
"drawnCards": [
{ "suit": "hearts", "value": "A" },
{ "suit": "diamonds", "value": "7" },
{ "suit": "clubs", "value": "K" },
{ "suit": "spades", "value": "2" },
{ "suit": "hearts", "value": "10" }
],
"remainingCount": 47,
"deckState": "t//+///bDw=="
}
*/
// Draw more cards using previous deck state
const draw2 = await client.callTool('draw_cards', {
count: 3,
deckState: draw1.deckState
});
console.log(draw2);
/* Output example:
{
"drawnCards": [
{ "suit": "diamonds", "value": "Q" },
{ "suit": "clubs", "value": "5" },
{ "suit": "spades", "value": "J" }
],
"remainingCount": 44,
"deckState": "l//+//zbDw=="
}
*/
