}You can run a lightweight MCP server that always answers questions with a playful “no,” delivering a creative reason each time. It’s useful for testing, humor, or exploring how your MCP client handles a consistently negative response while still providing a structured tool interface.
Start the server locally so your MCP client can connect to it. Run the runtime that launches the MCP server, then configure your client to point at this server. Once running, your agent gains access to the query tool, which will respond with a firm “no” accompanied by a playful explanation for any input.
Prerequisites you need before installing:
# Ensure you have a runtime environment and a package manager available
# Install the MCP server package
uv pip install no-mcp-serverInstall the server package and prepare to run it with your MCP client setup.
Start the server using the runtime tool you typically use for MCP servers.
Example startup step you can follow:
uvx no-mcp-serverIf you are adding this server to your MCP client configuration, you can specify the command and arguments to run the server. The following example shows how to configure the MCP client to start the server via a runtime command.
{
"mcpServers": {
"no-mcp": {
"command": "uvx",
"args": ["no-mcp-server"]
}
}
}You can also attach a specific version of the server if your setup requires it. Use the same runtime command with the desired package tag.
{
"mcpServers": {
"no-mcp": {
"command": "uvx",
"args": ["[email protected]"]
}
}
}Provides an endpoint on your MCP client that, regardless of input, returns the word “no” along with a creative explanation.
