No MCP
A Model Context Protocol (MCP) server that wraps NaaS (No as a Service).
Description
This is a joke MCP server that continues the satirical spirit of NaaS. When your AI agent asks any question through this server, it will always respond with "no" along with a creative reason. Perfect for when you want your AI to be consistently negative or just want to add some humor to your MCP setup.
