Use this server to browse MongoDB collections and query documents from Claude Desktop or Cursor.

What it can do

• list-collections shows collections in a database and can filter by name prefix.
• find-documents runs a normal find query with filter, projection, sort, limit, and skip.
• aggregate-documents runs an aggregation pipeline and returns matching documents; write stages stay off unless you opt in.

Setup

Set this env var:

• MONGODB_URI: your MongoDB connection string. Get it from the Atlas connect flow at https://www.mongodb.com/docs/atlas/connect-to-database-deployment/ or build one with the MongoDB connection string docs at https://www.mongodb.com/docs/manual/reference/connection-string/

Claude Desktop config

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["-y", "@universal-mcp-toolkit/server-mongodb@latest"],
      "env": {
        "MONGODB_URI": "${MONGODB_URI}"
      }
    }
  }
}

Cursor config

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["-y", "@universal-mcp-toolkit/server-mongodb@latest"],
      "env": {
        "MONGODB_URI": "${MONGODB_URI}"
      }
    }
  }
}

Quick example

Ask Claude:

Use the MongoDB server to list collections in my default database, then check the last 10 documents in orders where status is failed and tell me the most common error messages.
