      We're excited to share some of the updates from our team, but first, we need to acknowledge and apologize for the outage early Thursday morning. We know Clerk is a critical to your application, and even brief downtime is unacceptable.

      Next.js MCP Server Integration
    
                
              
            
              
                
                  
      
        
          
            
              
        
          
      
    
        
      
            
          
        
      
    
                
              
            
              
                
                  
      We’ve introduced an official MCP server implementation built on Next.js, enabling your users to access their Clerk data using MCP clients such as Clause, Cursor, and other AI tools.
    
                
              
            
              
                
                  
       
    
                
              
            
              
                
                  
      Rather than requiring separate MCP servers with their own authentication protocols, our approach allows you to add MCP capabilities directly to your existing application through a single API endpoint. This eliminates the overhead of deploying and managing additional services - you can expose your app's functionality to AI tools without architectural complexity.
    
                
              
            
              
                
                  
       
    
                
              
            
              
                
                  
      The following snippet demonstrates how an MCP route handler would be configured in your Next.js application that supports users authenticating with Clerk:
    
                
              
            
              
                
                  
      
        
          
            
              
      
    
            
          
        
      
    
                
              
            
              
                
                  
       
    
                
              
            
              
                
                  
      This release focuses on Next.js support, with support for more frameworks coming soon. Support for legacy MCP clients is possible by using tools such as mcp-remote.

      Over the past few months, we’ve been hard at work extending the capabilities of our OAuth provider. These changes paved the way for Clerk as a supported MCP Authentication provider, as well as make it more adaptable for applications needing an OAuth server.
