SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build and maintain MCP servers using current SDK semantics, ensuring schemas, transport wiring, and registration logic stay aligned with contract-first patterns.

Core Features & Use Cases

  • Design and validate MCP servers with clear transport choices (stdio, HTTP) and stable registration APIs.
  • Enforce separation of domain logic from transport wiring and provide guardrails for idempotent tools and schema validation.
  • Use case: teams implementing MCP services across multiple transports can rely on a single, repeatable pattern for tools, resources, prompts, and servers.

Quick Start

Initialize a new MCP server pattern in your project and begin wiring registration, transport, and validation per this skill.

FAQPage Schema
How do I enforce MCP server patterns across multiple SDKs and transports?

You can enforce MCP server patterns by applying contract-first design, schema validation, and explicit transport selection to ensure registration logic stays aligned across different SDKs. This approach provides stable, repeatable guardrails for tools, resources, and prompts.

What is the best way to validate tool registration and schema in an MCP server?

The best way to validate tool registration is by using contract-first patterns that enforce schema validation and separate domain logic from transport wiring. This ensures idempotent tools and stable registration APIs across your MCP service.

How do I separate domain logic from transport wiring when building MCP servers?

To separate domain logic from transport wiring in MCP servers, apply design patterns that enforce explicit transport selection and contract-first schemas. This creates clear boundaries between business rules and stdio or HTTP transport connections.

Does this approach work for both stdio and HTTP-based MCP services?

Yes, this pattern enforcement works for both stdio and HTTP-based MCP services by providing a single, repeatable pattern for tool registration. It ensures verifiable guidance for minimal working examples across multiple transport types.

Why do I need contract-first design for MCP server development?

You need contract-first design for MCP server development to ensure schemas, transport wiring, and registration logic remain aligned with current SDK semantics. This prevents drift and maintains stable APIs across multiple transports.

What are the limitations of not using enforced server patterns for MCP tools?

Without enforced server patterns, MCP tools risk misaligned schemas, tightly coupled transport wiring, and unstable registration logic. Bypassing schema validation and explicit transport selection leads to inconsistent services across different SDKs.
