AI驱动的语义代码搜索作为MCP工具——由Windsurf逆向工程的SWE-grep协议驱动。

任何兼容MCP的客户端（Claude Code、Claude Desktop、Cursor等）都可以利用它通过自然语言查询搜索代码库。所有工具都通过npm捆绑——不需要系统级依赖（ripgrep通过@vscode/ripgrep，树通过tree-node-cli）。支持macOS、Windows和Linux。

工作原理

先修条件

• Node.js >= 18
• Windsurf账户 — 免费套餐可用（需要API密钥）

不需要安装 ripgrep——它是通过 @vscode/ripgrep 捆绑的。

安装

选项1：NPM（推荐）

选项2：来源

布置

1.获取你的Windsurf/Devin API密钥

服务器会自动从 Devin CLI/Desktop 或遗留的 Windsurf 安装中提取 API 密钥。你也可以在设置后使用 extract_windsurf_key MCP 工具，或者手动设置 WINDSURF_API_KEY。

桌面凭证的发现顺序如下：Devin，遗留的Deviv，然后是Windsurf。

Fast Context MCP

AI-driven semantic code search as an MCP tool — powered by Windsurf’s reverse-engineered SWE-grep protocol.

Any MCP-compatible client (Claude Code, Claude Desktop, Cursor, etc.) can use this to search codebases with natural language queries. All tools are bundled via npm — no system-level dependencies needed (ripgrep via @vscode/ripgrep, tree via tree-node-cli). Works on macOS, Windows, and Linux.

How It Works

You: "where is the authentication logic?"

Prerequisites

• Node.js >= 18
• Windsurf account — free tier works (needed for API key)

No need to install ripgrep — it’s bundled via @vscode/ripgrep.

Installation

Option 1: npm (Recommended)

# Latest stable release
npm install @sammysnake/fast-context-mcp

# Or beta/next release
npm install @sammysnake/fast-context-mcp@next

Option 2: From Source

git clone https://github.com/SammySnake-d/fast-context-mcp.git
cd fast-context-mcp
npm install

Setup

1. Get Your Windsurf/Devin API Key

The server auto-extracts the API key from Devin CLI/Desktop or a legacy Windsurf installation. You can also use the extract_windsurf_key MCP tool after setup, or set WINDSURF_API_KEY manually.

Desktop credentials are discovered in this order: Devin, legacy Deviv, then Windsurf.
