SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Solves the challenge of rapidly building modular MCP servers by providing a unified framework for defining tools, resources, prompts, and server composition.

Core Features & Use Cases

  • Modular server composition: mount, import, and proxy subservers.
  • Rich resource and prompt system: expose data and reusable prompts to LLMs.
  • Tool automation and context: typed tools with validation, context for logging and progress.

Quick Start

Run the FastMCP skill to initialize a minimal server exposing your tools and resources.

FAQPage Schema
How do I build a modular MCP server using FastMCP?

Build a modular MCP server using FastMCP by defining tools, resources, and prompts within a unified framework. Initialize the project via a standard SKILL.md entry point and organize runtime assets in optional scripts, references, and assets directories.

Can I mount and proxy subservers when composing MCP architectures?

You can compose MCP architectures by mounting, importing, and proxying subservers. This modular server composition allows you to expose tool APIs and model data access across local or cloud environments.

How does FastMCP expose data and reusable prompts to LLMs?

FastMCP exposes data and reusable prompts to LLMs through a rich resource and prompt system. This system allows you to model data access and define typed tools with validation and context for logging and progress.

Do I need a specific project structure to expose tool APIs with FastMCP?

You need a standard SKILL.md file with YAML frontmatter to expose tool APIs with FastMCP. This entry point enforces a standard structure, while optional directories organize runtime assets and metadata.

What is the best way to compose microservices using MCP?

Composing microservices using MCP is best handled by mounting and importing subservers. This approach standardizes server composition, enabling you to expose typed tools and resources efficiently.

Are there limitations when proxying local or cloud MCP subservers?

Proxying local or cloud MCP subservers requires organizing runtime assets and metadata within the standard SKILL.md framework. Proper structuring ensures tools, resources, and prompts are exposed correctly across environments.
