@mastra/brightdata

Bright Data web search and web fetch tools for Mastra agents.

Backed by the official @brightdata/sdk. Bright Data's SERP API and Web Unlocker bypass bot detection and CAPTCHAs, so the tools work on sites that block typical scrapers.

Installation

npm install @mastra/brightdata zod

Quick Start

Use createBrightDataTools() to get both tools with a shared configuration:

import { Agent } from '@mastra/core/agent';
import { createBrightDataTools } from '@mastra/brightdata';

const tools = createBrightDataTools();
// Or pass an explicit API token:
// const tools = createBrightDataTools({ apiKey: 'brd_...' });

const agent = new Agent({
  id: 'realtime-information-agent',
  name: 'Realtime Information Agent',
  instructions:
    'You are a realtime information agent. Use brightdata-search to find pages, and brightdata-fetch to read them.',
  model: 'anthropic/claude-sonnet-4-6',
  tools,
});

By default the tools read BRIGHTDATA_API_TOKEN from your environment. You can also pass { apiKey } explicitly.

Individual Tools

Each tool can be created independently:

import { createBrightDataSearchTool, createBrightDataFetchTool } from '@mastra/brightdata';

const search = createBrightDataSearchTool({ apiKey: 'brd_...' });
const fetch = createBrightDataFetchTool(); // uses BRIGHTDATA_API_TOKEN env var

Web Search (brightdata-search)

import { createBrightDataSearchTool } from '@mastra/brightdata';

const searchTool = createBrightDataSearchTool();

// When called by an agent, accepts:
// - query (required)
// - country: 2-letter code (e.g., 'us', 'gb')
// - start: result offset for pagination (e.g. 10 for the second page of 10 results)
//
// Returns:
// {
//   query: string,
//   results: Array<{ link, title, description }>,
//   currentPage: number
// }

Web Fetch (brightdata-fetch)

import { createBrightDataFetchTool } from '@mastra/brightdata';

const fetchTool = createBrightDataFetchTool();

// Accepts: url (required)
// Returns: { url, content }  // content is Markdown

Configuration

All tools accept the full BrightDataClientOptions from @brightdata/sdk (including timeout, webUnlockerZone, serpZone, rateLimit, etc.). If no API token is found, the tool throws a clear error at execution time.

RAG Pairing Example

Combine search and fetch for retrieval-augmented generation:

import { Agent } from '@mastra/core/agent';
import { createBrightDataTools } from '@mastra/brightdata';

const agent = new Agent({
  id: 'rag-agent',
  name: 'Research Assistant',
  model: 'anthropic/claude-sonnet-4-6',
  instructions: `You are a research assistant. Use brightdata-search to find relevant pages, then use brightdata-fetch to get full Markdown content from the best results.`,
  tools: createBrightDataTools(),
});
