MCP Mastery: Build, Secure, and Ship Model Context Protocol Servers track
Module 06 of 8~16 minPro

Designing Tools, Resources, and Prompts an LLM Can Actually Drive

Design for the model as the user: tool names, descriptions, and schemas an LLM can choose correctly, structured results, recoverable errors, idempotency and safe-by-default destructive actions, and tool vs resource vs prompt decisions.


§  You will learn
  • Write tool names, descriptions, and JSON schemas that an LLM selects and fills correctly on the first try, instead of guessing or flailing across your server
  • Return structured, parseable results and recoverable error surfaces so the agent can self-correct without a human in the loop
  • Decide correctly when to expose something as a tool, a resource, or a prompt, and design destructive actions to be idempotent and safe by default
  • Build discoverability habits (naming conventions, scoping, examples) that make a multi-tool server like LightRAG's 30 tools navigable to the model
