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

# Fast Context MCP [](https://www.npmjs.com/package/@sammysnake/fast-context-mcp) [](https://nodejs.org) [](LICENSE) [](https://mcpvault.io/servers/fast-context-mcp/health?utm_source=external_badge&utm_medium=referral&utm_campaign=mcp_health_report) 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?" │ ▼ ┌─────────────────────────┐ │ Fast Context MCP │ │ (local MCP server) │ │ │ │ 1. Maps project → /codebase │ 2. Sends query to Windsurf Devstral API │ 3. AI generates rg/readfile/tree commands │ 4. Executes commands locally (built-in rg) │ 5. Returns results to AI │ 6. Repeats for N rounds │ 7. Returns file paths + line ranges │ + suggested search keywords └─────────────────────────┘ │ ▼ Found 3 relevant files. [1/3] /project/src/auth/handler.py (L10-60) [2/3] /project/src/middleware/jwt.py (L1-40) [3/3] /project/src/models/user.py (L20-80) Suggested search keywords: authenticate, jwt.*verify, session.*token ``` ## Prerequisites - **Node.js** >= 18 - **Windsurf account** — free tier works (needed for API key) No need to install ripgrep — it's bundled via `@vscode/
