Cli & MCP server for msw (Mock Service Worker) for AI Agents with dynamic mocking
使用下面的配置,将此服务器添加到你的 MCP 客户端。
{
"mcpServers": {
"msw-mcp": {
"command": "npx",
"args": [
"msw-mcp@latest"
]
}
}
}Add MSW request handlers to the browser service worker at runtime. Accepts JavaScript handler code strings that will be executed in the browser.
Reset MSW request handlers in the browser service worker. If no handlers provided, removes all runtime handlers and keeps only initial ones. If handlers provided, replaces all handlers with the new ones.
Remove specific MSW request handlers from the browser service worker by URL patterns and optional HTTP methods.
Update existing MSW request handlers by replacing handlers that match specified URL patterns with new handler code. This is an atomic operation that removes old handlers and adds new ones in a single transaction.
Get the current status of the MSW service worker, including connection state, worker status, and active handlers.
MCP server for msw is a Model Context Protocol server that bridges AI agents with Mock Service Worker (MSW). It enables dynamic addition, updating, and removal of MSW network mocks directly from an AI assistant or command line, without restarting the application.
Register the server in your MCP client using the command npx msw-mcp@latest. Then use the /msw-setup prompt to scaffold the browser‑side integration (requires msw, @msw-mcp/client, and the worker bridge). Alternatively, use the msw-cli for terminal control.
/msw-setup promptmsw-cli`msw-cli` is a command‑line tool for terminal and script control; `msw-mcp` is the MCP server that enables AI assistants to manage mocks via MCP tools. Both use the same WebSocket bridge and core daemon.
Yes. The server depends on MSW running in a browser environment, and the `@msw-mcp/client` package must be loaded in the page to receive updates via the WebSocket bridge.
Install by registering the server in your MCP client config with `"command": "npx", "args": ["msw-mcp@latest"]`. Then run the `/msw-setup` prompt in the assistant to follow the scaffold steps.
It requires Node.js (for the MCP server) and the browser to load `msw`, `@msw-mcp/client`, and the worker file. The server is published on npm as `msw-mcp`.
The MCP server communicates via stdio (standard input/output) with the MCP client. The browser bridge uses WebSocket.
🚀 The fast, Pythonic way to build MCP servers and clients.
