Architecture#
Simplicity AI SDK uses a layered architecture. Your LLM and agent remain in the execution environment. Silicon Labs exposes capabilities through MCP servers, skills, and CLI tools that operate on the Simplicity SDK.


Architecture highlights:
Developer LLM - Understanding, generation, and contextual inference for your prompts.
Agent runtime - Planning, reasoning, and control in Visual Studio Code through GitHub Copilot or Codex.
Integration artifacts - MCP configuration, skills/workflows, and agent guidance bridge the agent to Silicon Labs tools.
MCP servers - Standardized tool descriptions and interfaces for local tool capabilities and knowledge base.
Silicon Labs software and tools - Project creation, build, debug, validation, device, and documentation tooling operate on the installed Simplicity SDK and CLI utilities.
Connected hardware - The development kit or adapter where firmware is flashed, run, and debugged.
Iterative execution - The agent calls tools, reviews results with you, and continues until the task succeeds or needs your input.
Simplicity AI SDK provisions MCP servers, tools, skills, and execution environments so your IDE can discover them automatically after install.
