build-clean-mcp-architecture

You can enforce clean architecture boundaries in an MCP server by validating separation of concerns across domain, application, handlers, and infrastructure layers using dependency-cruiser gates and strict import path rules.

The best way to refactor monolithic tool definitions in a TypeScript MCP server is to follow a structured playbook that moves logic into per-tool handlers and per-feature use cases, wiring them through a single composition root.

Dependency-cruiser works with MCP server folder layouts by auditing import flows between canonical directories like gateways, presenters, and shared code, ensuring type-safety and preventing unauthorized cross-layer dependencies.

Yes, you can centralize environment reads when bootstrapping an MCP server by enforcing a strict config seam that isolates configuration logic from domain and application layers during the canonical bootstrap wiring process.

You need a canonical layered architecture for your MCP server when monolithic tool definitions and unmanaged import paths begin threatening type-safety, code maintainability, and clear separation of concerns across features.

Bootstrapping an MCP server without clean architecture risks circular dependencies, scattered environment reads, and uncontrolled infrastructure coupling, making type-safety validation and feature refactoring significantly harder as the codebase scales.
