{
    "mcpServers": {
      "mongodb-readonly": {
        "command": "uv",
        "args": [
          "--directory",
          "/PATH/TO/mongo-mcp",
          "run",
          "mcp-server-mongo"
        ],
        "env": {
          "db_uri": "mongodb://your-mongodb-connection-string"
        }
      }
    }
}

Configuration notes:

• /PATH/TO/mongo-mcp: Replace with your actual project path
• db_uri: Replace with your MongoDB connection string

The server supports the following MongoDB read-only operations:

• Document queries (find)
• Aggregation operations (aggregate)
• Count operations (count)
• Server information retrieval (serverInfo)
