GREB MCP Server

Semantic code search for AI agents. Search your codebase using natural language queries.

Installation

Install Greb globally using pip or npm:

Python:

pip install cheetah-greb

Node.js:

npm install -g cheetah-greb

✅ No native compilation required! Greb uses WASM-based tree-sitter for AST parsing, which works everywhere without C++ compilation. This means it installs and runs on any platform - Windows, macOS, Linux, Docker, CI/CD - without build tools.

Configuration

Add to your MCP client config (Cursor, Windsurf, Claude Code, etc.):

Python installation:

{
  "mcpServers": {
    "greb-mcp": {
      "command": "greb-mcp",
      "env": {
        "GREB_API_KEY": "grb_your_api_key_here"
      }
    }
  }
}

Node.js installation:

{
  "mcpServers": {
    "greb-mcp": {
      "command": "greb-mcp-js",
      "env": {
        "GREB_API_KEY": "grb_your_api_key_here"
      }
    }
  }
}

Claude Code Setup

Mac/Linux (Python):

claude mcp add --transport stdio greb-mcp --env GREB_API_KEY=grb_your_api_key_here -- greb-mcp

Windows PowerShell (Python):

claude mcp add greb-mcp greb-mcp --transport stdio --env "GREB_API_KEY=grb_your_api_key_here"

Usage

Ask your AI assistant to search code naturally:

"Use greb mcp to find authentication middleware"
"Use greb mcp to find all API endpoints"
"Use greb mcp to look for database connection setup"
