概览

What is Blowback?

Blowback is a Model Context Protocol (MCP) server that integrates front-end development servers (e.g., Vite) with AI tools like Claude Desktop and Cursor. It provides tools for browser automation, console log capture, HMR monitoring, and screenshot management.

How to use Blowback?

Install via npm as blowback-context. Add an MCP configuration entry (e.g., in .mcp.json or .cursor/mcp.json) specifying the command npx -y blowback-context and the optional environment variable PROJECT_ROOT (defaults to current working directory). Then use claude mcp add blowback -s project -e PROJECT_ROOT=/path/to/your/project -- npx -y blowback-context in Claude Code.

FAQ from Blowback

What development servers does Blowback support?

Blowback aims to support various FE development servers, not only Vite.

How are screenshots stored and managed?

Screenshot images are stored in {PROJECT_ROOT}/.mcp_screenshot/ directory, and metadata is managed in a SQLite database in a temporary directory. It is recommended to add .mcp_screenshot/ to .gitignore.

Does Blowback require a real browser?

Yes. It uses Playwright to control a Chrome browser instance for visual inspection, screenshot capture, and DOM manipulation.

What is the checkpoint system?

Checkpoints are named snapshots tied to a unique data-id in a <meta name="__mcp_checkpoint" data-id=""> tag inserted into the page <head>. They allow separate recording of logs, screenshots, and DOM snapshots for specific versions.

Does Blowback support MCP prompts in all clients?

No. Cursor Chat does not support MCP prompt functionality; the init prompt is only available in Claude Code. If needed, users must manually input the prompt instructions.
