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.

Installation

uv pip install no-mcp-server

Usage

Running with STDIO (Default)

The server runs with stdio transport by default, suitable for MCP clients like Claude Desktop:

uvx no-mcp-server

Running as HTTP Server

You can run the server as an HTTP endpoint by setting the MCP_TRANSPORT environment variable:

MCP_TRANSPORT=http uvx no-mcp-server

The server will start on http://0.0.0.0:8000/mcp by default. You can customize the HTTP configuration:

MCP_HTTP_PATH=mcp uvx no-mcp-server

Configuration

The server can be configured via environment variables:

Adding to MCP Clients

Claude Desktop (STDIO)

Add this configuration to your MCP client settings:

{
  "mcpServers": {
    "no-mcp": {
      "command": "uvx",
      "args": ["no-mcp-server"]
    }
  }
}

Or with a specific version:

{
  "mcpServers": {
    "no-mcp": {
      "command": "uvx",
      "args": ["no-mcp-server@0.2.1"]
    }
  }
}

Using HTTP Transport

If you're running the server as HTTP, configure your MCP client to connect to the HTTP endpoint (e.g., http://localhost:8000/mcp).

Once configured, your AI agent will have access to the query tool, which will respond to any question with "no" and a creative explanation.
