概要

What is unplugin-mcp?

unplugin-mcp is a unified MCP (Model Context Protocol) plugin that creates and manages an MCP server, providing AI assistants with tools to analyze your codebase, inspect build configuration, and control the build process. It works with multiple JavaScript build tools through the unplugin abstraction, including Rollup, Vite, Webpack, ESBuild, Rspack, and Rolldown.

How to use unplugin-mcp?

Install the plugin with pnpm add -D unplugin-mcp (or the bundler-specific package like rollup-plugin-mcp). Add it to your build config (e.g., rollup.config.js) and provide built-in or custom tools via the provideUnpluginMcpTools option. The MCP server starts automatically when you run your build tool in watch mode. Then configure your MCP client (e.g., Cursor) to connect to the server’s SSE endpoint, typically http://localhost:14514/mcp/sse.

Key features of unplugin-mcp?

Cross-platform MCP integration for multiple JavaScript build tools.
Bi-directional AI integration for both reading and modifying builds.
Rich built-in tools for module, config, error, and size analysis.
Extensible tool framework via the UnpluginMcpTool interface.
Seamless integration with build tool plugin hooks (e.g., Rollup).
Persistent server that stays alive in watch mode.
Standard HTTP + SSE transport for broad MCP client compatibility.

Use cases of unplugin-mcp?

AI assistant analyzing module dependencies and imports in a Rollup project.
Inspecting current build configuration through a chat interface.
Debugging build errors by asking the AI to examine error details.
Enabling an AI to modify the build process (e.g., adjust plugin options) during development.
Exposing project-specific information to MCP clients via custom tools.
