Set up the MCP server

Kubb ships a Model Context Protocol server. It exposes code-generation tools to any MCP-capable client. Once connected, your editor or agent runs Kubb generation, validates schemas, and inspects configuration from the chat.

IMPORTANT

The built-in MCP server needs Kubb v5 or higher.

NOTE

This page covers using Kubb tooling inside your editor over MCP. To generate an MCP server from your OpenAPI spec, see @kubb/plugin-mcp instead.

Starting the server

Run the server with one command. It communicates over stdio, the transport that every major LLM client speaks.

Terminal

kubb mcp

Client configuration

Claude Desktop

Add this to your claude_desktop_config.json. On macOS it usually lives at ~/Library/Application Support/Claude/claude_desktop_config.json.

Claude Desktop

{
  "mcpServers": {
    "kubb": {
      "command": "npx",
      "args": ["kubb", "mcp"]
    }
  }
}

Cursor

Open Settings → MCP and add a new server entry.

Cursor

{
  "mcpServers": {
    "kubb": {
      "command": "npx",
      "args": ["kubb", "mcp"]
    }
  }
}

VS Code (GitHub Copilot)

Add this to your .vscode/mcp.json for the workspace. For a global setup, run MCP: Open User Configuration in the Command Palette.

.vscode/mcp.json

{
  "servers": {
    "kubb": {
      "command": "npx",
      "args": ["kubb", "mcp"]
    }
  }
}
