You build an MCP server by separating transport from business logic and registering callable tools, readable resources, and reusable prompt templates for AI clients. This approach uses schema-first interfaces for predictable server behavior.

For Model Context Protocol servers, stdio transport is chosen for local clients, while Streamable HTTP is used for remote clients. Selecting the right transport ensures reliable communication between the server and AI clients.

To validate tool inputs when creating a Model Context Protocol server, use schema-first patterns and Zod validation. This keeps server interfaces predictable and ensures reliable behavior when AI clients call registered tools.

Yes, you can expose resources and prompt templates to AI clients. The architecture supports registering readable resources and reusable prompt templates alongside callable tools within the same Model Context Protocol server implementation.

The best way to structure a Model Context Protocol server and avoid shifting SDK issues is to apply SDK-aware registration patterns aligned with current MCP documentation, cleanly separating transport from core business logic.
