add useless toolkit mcp servers

[cubicwork]

This PR is introduce uselesstoolkit mcp servers - MCP support for uselesstoolkit.com，uselesstoolkit is an api set for developers, include random password, ip2geo etc. and some useful web application like json playground, timestamp convert and encoding/decoding lab ...

Description

Server Details

• Server: uselesstoolkit
• Changes to:
  • /mcp/rapidapi/password for password generation api
  • /mcp/rapidapi/ip for ipgeo api

Motivation and Context

This submission registers new remote HTTP MCP endpoints provided by UselessToolkit.com. It expands the ecosystem of available public MCP servers, offering developers and users immediate access to utility tools via RapidAPI without needing to host local servers.

• Accuracy & Utility: LLMs often struggle with generating truly random secure strings or performing real-time data lookups (like IP Geolocation). These tools provide deterministic, API-backed execution for these specific tasks.
• Ease of Access: By exposing these tools via standard MCP HTTP endpoints, it allows users to integrate utility functions into their AI clients (like Claude Desktop) purely through configuration, eliminating the need to install or run local code/containers.

How Has This Been Tested?

Tested locally with an MCP-compatible LLM client (VSCode Copilot).

I think at the current scale of uselesstoolkit, can you move this to the community servers section?

Then we can get this approved and merged :)
