Perplexity

Turn Klaviyo audience segments into queryable indexes

Stop writing complex filters to find who your customers are. LlamaIndex pulls your active cohorts using `list_audience_segments` and indexes the results directly into your vector store. You can then query your knowledge base to find out who your high-value customers are. The agent uses `get_profile` to pull specific details and grounds its answers in real-time CRM data.

Query your email campaigns using LlamaIndex RAG

Fetch live marketing data using `list_email_campaigns` and `get_campaign_details` to build a local index of your marketing history. This prevents your agent from hallucinating what your emails actually said. When you ask about your messaging strategy, the agent queries this index and references the actual text returned by the MCP Server, giving you factual answers about what went out.

Index active automation flows via MCP

Pull your entire automation setup using `list_automation_flows` and feed the step-by-step details from `get_flow_details` into LlamaIndex. This creates a searchable map of your customer journeys. You can ask your agent which flows target abandoned carts or welcome sequences. The agent searches the indexed flow structures to pinpoint gaps in your marketing setup.
