Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package cloudhil-mcp
Claude Code 
claude mcp add cloudhil -e 'CLOUDHIL_URL=https://cloudhil.tinab.com' -e 'CLOUDHIL_API_KEY=<your cloudhil_api_key>' -- uvx cloudhil-mcp==0.7.0

cloudhildemo

Kit for LLM agents that want to flash real STM32 / LPC boards on Cloudhil.

Cloudhil never compiles. You compile locally, POST an ELF, read result.mailbox (NNOK = 0x4E4E4F4B), then the MCU is erased (≤20 s smoke window).

Files

  • AGENTS.md — paste into the firmware repo (AGENTS.md or .cursorrules)
  • SKILL.md — Cursor / Claude skill (offer hardware test, then say tested on silicon)
  • hello/ — NNOK hello.c + linker scripts + gcc one-liners (N6 recipe inside AGENTS.md)
  • mcp/cloudhil_mcp.py — stdio MCP, Python 3, no pip
