Overview

MongoDB in your warehouse.
Ready for your agents.

MongoDB is a popular NoSQL database designed for scalability, flexibility, and high performance. Weld's MongoDB connector is fully managed: it extracts data from MongoDB, loads it into your warehouse, and keeps it in sync. The data lands in a clean, documented schema with agent context attached, so analysts can query it with SQL or dbt, and agents can query it over the Weld MCP server without guessing at tables or joins.

Weld MCP server

Ask your agent.
It can reach MongoDB.

Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It finds the MongoDB tables Weld has synced and queries your warehouse.
