Overview

AI-generated overview

Cloudhil lets an assistant flash pre-built STM32/LPC ELF firmware onto real Nucleo/Discovery boards over HTTPS; it does not compile code.

What you can do
  • Flash pre-built STM32/LPC ELF files onto real Nucleo/Discovery boards over HTTPS.
  • Register an agent to obtain a bearer key, then submit an ELF and read the result mailbox (NNOK signals a smoke result).
  • The board is erased after a short smoke window of up to about 20 seconds.
  • Compilation is not supported; firmware must be built locally first.
When to use it
Use it when you want an assistant to put already-compiled firmware onto physical STM32 or LPC hardware for a quick smoke test, rather than simulating or building code.
Requirements
Runs as a local Python 3 stdio process (PyPI package cloudhil-mcp, no pip dependencies per the README). Needs network access to the Cloudhil API base URL set in CLOUDHIL_URL, and a CLOUDHIL_API_KEY bearer token, which the register_agent tool can obtain. Desktop only.
Before you install
The API key is a secret sent as a bearer token; keep it out of logs. Submitting firmware writes to and then erases real hardware, so a wrong ELF can brick or wipe a board. Firmware is uploaded to a third-party service (Cloudhil).

Installation

In SourceWeft

  1. Open Cloudhil in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
