This guide outlines how to create a system with a host, client, and SSE-based MCP server as per the Model Context Protocol (MCP) specification.
The Model Context Protocol (MCP) defines a Client-Host-Server architecture that facilitates the integration of AI/LLM systems. The host manages multiple client instances, coordinates AI integration, and enforces security. Clients maintain a one-to-one connection with a server, handling protocol negotiation and message routing. Servers expose resources, tools, and prompts via MCP primitives, operating independently with security constraints. This setup involves a desktop application ('Claude Desktop') integrating a FastAPI server for user interactions and an MCP client for server communication. The FastAPI server handles user requests and database operations, while the SSE-based MCP server provides prompts, resources, and tools. The architecture emphasizes easy server build, high composability, server isolation, and progressive feature addition.
Features
- Easy Server Build: Servers focus on specific capabilities, with the host handling orchestration.
- High Composability: Modular components combine seamlessly via a shared protocol.
- Server Isolation: Only necessary context is shared, with the host controlling cross-server interactions.
- Progressive Feature Addition: Minimal core protocol with negotiated capabilities for extensibility.
Tools
