Parameters: - query (string, required): Natural language search query - keywords (object, required): Search configuration - keywords.primary_terms (string array, required): High-level semantic terms (e.g., "authentication", "database") - keywords.code_patterns (string array, optional): Literal code patterns to grep for - keywords.file_patterns (string array, required): File extensions to search (e.g., ["*.ts", "*.js"]) - keywords.intent (string, required): Brief description of what you're looking for - directory (string, required): Full absolute path to directory to search Example: { "query": "find authentication middleware", "keywords": { "primary_terms": ["authentication", "middleware", "jwt"], "code_patterns": ["authenticate(", "isAuthenticated"], "file_patterns": ["*.js", "*.ts"], "intent": "find auth middleware implementation" }, "directory": "/Users/dev/my-project" } Response includes: - File paths - Line numbers - Relevance scores - Code content - Reasoning for each match USAGE EXAMPLES 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" "Use greb mcp to find where user validation happens" "Use greb mcp to search for error handling patterns" LINKS Website: https://grebmcp.com Documentation: https://grebmcp.com/docs Get API Key: https://grebmcp.com/dashboard/api-keys
