Original: MCP Design Patterns: 6 Architectures for Your AI Tools

Short summary

A practical guide to six architectural patterns for MCP (Model Context Protocol) servers, covering thin API wrappers, composite task-level tools, resource-based context exposure, and more. Each pattern includes fit criteria, risks, and design rules drawn from real-world experience. The article emphasizes that good MCP design is about choosing the right abstraction level, not just exposing every endpoint as a tool.

  • •Six MCP server architecture patterns with decision criteria
  • •Patterns range from thin API wrappers to composite tools to resource-based context servers
  • •Key risk: tool bloat when every endpoint becomes a separate tool

Generated with AI, which can make mistakes.
