To build an MCP server using Next.js, centralize your Zod schemas and core logic in a `lib/` directory, then configure your mcp-handler within `app/api/[transport]/route.ts` to expose tools. This pattern ensures logic is shared efficiently between server actions and MCP responses.

Next.js handles Model Context Protocol routing by minimizing business logic in the API route file, typically `app/api/[transport]/route.ts`. This file focuses solely on handler configuration, delegating the actual processing to shared core logic and reusable server actions.

Yes, you can use the same logic for Next.js server actions and MCP tools. By defining shared Zod schemas and core logic in a central library, both UI interactions via server actions and external MCP client requests execute identical functions.

The best way to connect an MCP client to a Next.js application is by integrating mcp-remote. This setup facilitates seamless client-server communication, allowing tools like Claude Desktop to interact directly with your Next.js API routes.

Yes, this MCP server pattern supports shared schema validation using Zod. It centralizes schemas in the `lib/` directory, ensuring both the lightweight API routing and reusable server actions validate inputs consistently before processing AI service requests.

You should reuse server actions for your MCP server logic to ensure consistency between web UI interactions and AI client responses. This approach prevents code duplication by routing both interfaces through a single source of truth for core logic and validation.
