How to Use the EmailListVerify MCP in LlamaIndex

Q: Can I query my EmailListVerify credit balance using LlamaIndex?

Yes, by calling getremainingcredits, the agent retrieves the live count. You can store this as a temporary context variable for your agent's current session.

Index verification results for search

Turn your validation history into a searchable knowledge base. By passing outputs from `verify_single_email` into your vector store, you make historical verification data instantly queryable by your agent. This setup allows your agent to answer questions about why specific contacts were flagged without re-running the validation. It grounds your agent's decisions in the actual data returned by the API.

Audit verification health with LlamaIndex

Run `quick_verification_health_audit` to get a snapshot of your account's success rates. LlamaIndex stores this summary as a document, letting you query trends over time or compare performance across different list uploads. Keeping this data indexed helps you spot patterns in your contact quality. You get a clear picture of your sender health directly through your existing agent interfaces.

Track account metadata as context

Retrieve account settings and configuration details using `get_emaillistverify_metadata`. By indexing this metadata, you give your agent the context it needs to understand your current account constraints and configuration. This makes the agent aware of how your account is set up without requiring manual updates. It keeps your knowledge base current with the state of your verification service.
