SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires mcp[cli], and includes scripts (resource) and references (resource) components.

What problem does it solve?

MCP development often requires bespoke glue code to coordinate servers and clients, transport layers, and auth, making integrations slow and error-prone.

Core Features & Use Cases

  • Server creation with FastMCP to expose resources, tools, and prompts
  • Client development with authentication and multi-transport support (stdio, SSE, streamable-http)
  • Lifecycle management, stateful/stateless configurations, and JSON-friendly responses

Quick Start

Install the MCP SDK, scaffold a FastMCP server, define tools, resources, and prompts with decorators, and run the server with your preferred transport.

FAQPage Schema
How do I build an MCP server to expose tools and resources to LLM applications?

To build an MCP server, scaffold a FastMCP instance and use decorators to define tools, resources, and prompts. This approach standardizes communications between your LLM applications and external services with minimal glue code.

What transports can I configure for MCP client and server communication?

MCP client and server communication supports multiple transports including stdio, SSE, and streamable-http. You can configure these options to manage stateful or stateless integrations across different network environments.

How does OAuth authentication work for AI-to-service integrations in MCP?

OAuth authentication for AI-to-service integrations is managed directly within the MCP client. The SDK handles the authentication flow, enabling secure access to protected external resources without bespoke auth glue code.

Can I manage server lifecycle and stateful configurations with the MCP SDK?

Yes, the MCP SDK supports lifecycle management and stateful or stateless configurations. It provides lifespan management options and JSON-friendly responses to maintain session state across server interactions.

What is the best way to standardize communications between an LLM and external services?

The best way to standardize LLM communications is using the MCP protocol with FastMCP. It replaces bespoke integration code with a structured framework for exposing tools, resources, and prompts across multiple transports.

Do I need mcp[cli] to scaffold FastMCP servers and clients?

Yes, the mcp[cli] dependency is required to scaffold and run FastMCP servers and clients. It provides the command-line interface needed to initialize your server and configure transport layers like SSE or stdio.
