Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to reliness.co.uk, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that generates passwords, random numbers, strings, colours, usernames and card draws from a cryptographically secure random source.

What you can do: Generate cryptographically secure passwords with configurable length and character types
Create random integers in a range, random strings from a chosen character set, and hex colours
Build unique usernames from first name, last name and birth year with a random suffix
Draw cards from a shuffled standard 52-card deck
When to use it: Useful when an assistant needs trustworthy random values rather than pseudo-random guesses: creating passwords or test credentials, picking random numbers or strings, generating placeholder usernames or colours, or dealing cards for games and simulations.
Requirements: A remote streamable HTTP endpoint; no local install. An optional Authorization header with a bearer key raises the free daily allowance; a free key is obtained from the provider's key endpoint. Each tool call costs 1 credit.

Before you install

Generated passwords and usernames are returned through the remote service, so treat them as exposed to that provider. Calls consume credits and the optional bearer key is a secret to keep private. The service is a third party, so avoid sending sensitive context in requests.

Installation

In SourceWeft

Open UK Data: Secure generators in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/uk.co.reliness%2Fgenerators/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
