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.
