🔍 Complete Bright Data MCP Utilization

DISCOVER — The Web Intelligence Engine

const comprehensiveDiscovery = await Promise.all([ this.discoverFromGoogle(enhancedKeywords), this.discoverFromGoogleNews(newsVariations), this.discoverFromGoogleScholar(academicTerms), this.discoverFromBing(alternativeQueries), this.discoverFromTwitterAdvanced(trendingHashtags), this.discoverFromFacebookAdvanced(publicPosts), this.discoverFromInstagramAdvanced(visualContent), this.discoverFromTikTokAdvanced(viralVideos), this.discoverFromLinkedInAdvanced(professionalDiscussion), this.discoverFromRedditAdvanced(communityThreads), this.discoverFromYouTubeAdvanced(videoContent), this.discoverFromFactCheckSites(claim), this.discoverFromGovernmentSources(officialStatements), this.discoverFromAcademicInstitutions(researchPapers), this.discoverFromNewsAgencies(breaking), this.discoverFromTelegramChannels(liveDiscussion), this.discoverFromDiscordCommunities(gamingNews), this.discoverFromWhatsAppPublic(viralMessages), this.discoverFromSignalGroups(privacyFocused) ]); 

ACCESS — Unstoppable Content Retrieval

const accessStrategy = await this.determineOptimalAccess(discoveredSources); const results = await Promise.all(sources.map(async (source) => { switch(source.complexity) { case 'STANDARD': return this.useWebScraperAPI(source); case 'JAVASCRIPT_HEAVY': return this.useBrowserAPI(source); case 'PROTECTED': return this.useWebUnlockerAPI(source); default: return this.useAdaptiveAccess(source); } })); 

EXTRACT — Structured Intelligence at Scale

interface ExtractedEvidence { content: string; source: CredibilityScore; timestamp: Date; author: AuthorCredentials; engagement: SocialMetrics; sentiment: SentimentAnalysis; entities: NamedEntity[]; factCheckStatus: VerificationStatus; multimedia: MediaAnalysis[]; } 

INTERACT — Dynamic Web Engagement

const interactionResults = await this.executeBrowserActions([ { action: "navigate", url: targetUrl }, { action: "wait", selector: ".content-loader", timeout: 10000 }, { action: "scroll", direction: "down", amount: 5 }, { action: "click", selector: ".show-more-button" }, { action: "extract", selector: ".fact-check-content" }, { action: "screenshot", filename: "evidence.png" } ]);
