SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The MCP Builder addresses the lack of a structured, end-to-end process for constructing MCP servers, delivering a fixed 4-phase workflow, deterministic framework selection between Python FastMCP and TypeScript MCP SDK, and an integrated evaluation framework to ensure consistency, security, and scalability.

Core Features & Use Cases

  • Enforces a four-phase build: Research, Implement, Review, Evaluate, to guide development end-to-end.
  • Provides deterministic framework selection between Python FastMCP and TypeScript MCP SDK based on team requirements.
  • Includes a built-in evaluation framework with 10 complex, read-only questions to validate server behavior.
  • Supplies design principles, best practices, and security guidelines to shape robust MCP servers.
  • Use cases: building a new MCP server, choosing language/framework, performing quality reviews, and running evaluations.

Quick Start

Run the MCP Builder to start a 4-phase MCP project by selecting your language, consulting the six reference files, and following the 4-phase workflow through design, implementation, review, and evaluation.

FAQPage Schema
How do I build an MCP server for AI agents?

To build an MCP server for AI agents, you follow a fixed 4-phase workflow: Research, Implement, Review, and Evaluate. This process guides development end-to-end while enforcing design principles and security guidelines.

How do I choose between Python FastMCP and TypeScript MCP SDK for my server?

Choosing between Python FastMCP and TypeScript MCP SDK is handled by a deterministic framework selection process based on your specific team requirements. This ensures the chosen language aligns with your project's needs.

What is the MCP server evaluation process?

The MCP server evaluation process uses a built-in framework featuring 10 complex, read-only questions to validate server behavior. It ensures consistency, security, and scalability before deployment.

Can I use this workflow for an existing MCP server quality review?

Yes, you can use this workflow for a quality review of an existing MCP server. It includes a 4-item review checklist and an evaluation phase to assess design principles, security, and behavior.

Does the MCP builder execute code during the server generation process?

No, the MCP builder does not execute code during the server generation process. It remains stateless, providing structured guidance, enforcing phase sequencing, and validating behavior through read-only questions.
