Frequently asked questions
How do I report usage events for a specific customer?
Use the ingest_events tool. You'll need to provide an array of event objects containing the customer_id, event_name, timestamp, and an idempotency_key to ensure usage is only counted once.
Can I see how much a customer will be charged before the billing cycle ends?
Yes! The get_upcoming_invoice tool allows you to fetch the draft invoice for any active subscription_id, giving you real-time visibility into accrued costs.
How do I manage prepaid credits or balances?
You can use create_ledger_entry to add or remove credits from a customer's balance. You can also use fetch_ledger to view the current state of a customer's credit ledger.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Orb tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
