MongoDB Lens MCP server

MongoDB Lens is a small helper program that connects your AI assistant to a MongoDB database. MongoDB is a place where apps store their data, and this helper lets your AI look inside it, ask questions and make changes for you. It is handy if you work with data and would rather describe what you want than write database code.

What this MCP server does

You tell your AI what you want in normal words, like listing databases or finding orders from last week. The AI passes that request to MongoDB Lens, which talks to your MongoDB database. The helper runs the query, gathers the results and hands them back to the AI. The AI then shows you the answer in the chat, as a list, a table or a short summary.

What you can do with it

• List your databases, collections and the documents inside them
• Find documents that match conditions you describe
• Count, group and summarize your data
• Insert, update or delete documents
• Create indexes to make slow queries faster
• Export query results as JSON or CSV
• Check database and collection statistics

Try asking your AI

• “List all databases I can access”
• “Show me the 10 most recent orders in the orders collection”
• “How many users signed up last month?”
• “Find all products with a price above 100 and sort by name”

What it gives back to you

You get answers in the chat: lists of databases or collections, matching documents, counts and summaries. It can also hand back exported files in JSON or CSV. When it makes a change, like inserting or updating a document, it tells you what it did.

Who it's for

Anyone who works with MongoDB data and wants to explore or edit it by chatting instead of writing database code.
