A Command-Line Tool for Random Strings

This server gives Claude Code a single function, `generate_random_string`, turning it into a powerful command-line utility. It's built on Node.js's `crypto.randomBytes()`, so the output is secure enough for production secrets. Now you can generate a secure key directly in your terminal and pipe it to another command. It's perfect for scripting, infrastructure setup, or just grabbing a quick password from your shell.

Automate Secret Generation in CI/CD

Because Claude Code is headless, you can use this tool in any automated environment. Run it in a GitHub Action to generate a temporary access token or in a cron job to rotate credentials. It's a dependency-free way to handle secrets. The output is just a string sent to stdout, so it's easy to use with standard shell tools. Assign it to a variable, write it to a file, or pass it to a secret manager's CLI. It just works.

A Dedicated MCP Server for Your Scripts

Stop maintaining your own little Python or Bash script for generating tokens. This MCP Server is managed, reliable, and does one thing well. Connect it to Claude Code once, and it's available as a command everywhere. You specify the length and charset (hex, numeric, base64, etc.) with simple flags. This makes your scripts cleaner and removes a common point of failure and insecurity.

Setup guide

Set up Crypto Random String MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see crypto-random-string-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest Crypto Random String transactions." It will automatically discover and invoke the available Crypto Random String tools.

Common questions about Crypto Random String MCP in Claude Code

You add the server's URL to Claude Code via the CLI. Then you can call it like any other command: `claude mcp crypto-random-string-mcp generate_random_string --length 32 --charset hex`. The result is printed to standard output.

Yes, that's what it's designed for. You can pipe the output or use command substitution. For example: `export API_KEY=$(claude mcp crypto-random-string-mcp generate_random_string)`.

You can specify a charset using a flag. It supports `hex`, `alphanumeric`, `base64`, `url_safe`, and `numeric`. This is useful for generating tokens that fit specific requirements without extra processing.

This MCP tool provides a simpler, more consistent interface across different systems, especially inside CI/CD runners where available tools can vary. It also gives you convenient charset options like `numeric` or `distinguishable` that OpenSSL doesn't offer out of the box.

The server is completely stateless. It processes an incoming request containing only the string length and charset type, generates the string, and sends it back in the response. No request data or generated strings are ever logged or stored.
