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.
Quick Start
Use the Hosted Instance
No installation required! Use the publicly hosted MCP server:
{
"mcpServers": {
"no-mcp": {
"url": "https://no-mcp.clabouri.dev/mcp"
}
}
}
Add this configuration to your MCP client settings (e.g., Claude Desktop) to start using the refusal agent immediately.
Installation
If you prefer to self-host or run locally:
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:
| Variable | Description | Default |
|---|---|---|
MCP_TRANSPORT |
Transport protocol (stdio or http) |
stdio |
MCP_HTTP_HOST |
HTTP server host (when using http transport) | 0.0.0.0 |
MCP_HTTP_PORT |
HTTP server port (when using http transport) | 8000 |
MCP_HTTP_PATH |
HTTP endpoint path (when using http transport) | /mcp |
NO_BASE_URL |
NaaS API base URL | https://naas.isalman.dev |
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.
