Update app/[transport]/route.ts with your tools, prompts, and resources following the MCP TypeScript SDK documentation.
Notes for running on Vercel
- To use the SSE transport, requires a Redis attached to the project under
process.env.REDIS_URLand toggling thedisableSseflag tofalseinapp/mcp/route.ts - Make sure you have Fluid compute enabled for efficient execution
- After enabling Fluid compute, open
app/route.tsand adjustmaxDurationto 800 if you using a Vercel Pro or Enterprise account - Deploy the Next.js MCP template
