Query mailing records via LlamaIndex

Turn your print history into a vector store. By running `list_mail_jobs` and feeding the output to your index, you make every past mailing searchable. Your agent can now answer questions about previous shipments. It looks up job specifics without needing to re-fetch raw API data every time.

Ground your agent in real Click2Mail data

Stop hallucinating about your mailing status. Your LlamaIndex agent calls `get_mail_job_details` to retrieve the actual state of a document in production. This ensures your RAG pipeline reports facts. If a job is stuck or completed, the system knows exactly why based on the live API response.

Manage balances using this MCP Server

Keep your agent informed about your remaining postage credits. Your indexing pipeline triggers `get_mail_credit_balance` to monitor your account health. This data becomes part of your searchable index. You can ask your agent if you have enough balance for a new campaign before you start building the index.
