Index store configurations for grounded RAG

The `get_store_details` tool fetches the raw configuration and metadata of your digital storefront from Lemon Squeezy. LlamaIndex ingests this structured data, indexing it into your vector database so your support agent answers questions based on real store rules. This setup eliminates hallucinated Lemon Squeezy store policies in your LlamaIndex RAG application. The agent queries the index, pulls the latest store details, and drafts replies that match your actual setup.

Build a searchable customer knowledge base using this MCP Server

The `list_all_customers` tool retrieves your complete customer directory from the Lemon Squeezy billing platform. Your LlamaIndex pipeline converts these profiles into vector embeddings, making customer history searchable via semantic queries. When a user submits a ticket, LlamaIndex searches this local index of Lemon Squeezy data first. It matches the query with historical records from `get_customer_details` to give the model full context.

Query subscription histories with zero hallucinations

The `list_all_subscriptions` tool exposes all active and historical customer agreements in your Lemon Squeezy account. LlamaIndex indexes these records to let your agent answer complex churn questions without querying the database directly. Your LlamaIndex system pulls live data through `get_subscription_details` to verify active Lemon Squeezy statuses. This direct connection ensures your financial summaries are always accurate.
