firmware-test-farm-mcp

An MCP server that lets an AI agent flash a compiled firmware binary onto a real, physical embedded dev board, run it, and get back structured pass/fail results — serial output, crash info, reset reason, timing — instead of a simulator or a description of what should happen.

This repo hosts the server.json manifest for the MCP Registry. The server itself runs as a hosted, always-on remote endpoint — there's no package to install.

Connecting

Sign up and create an API key from the dashboard, then point any MCP client that supports Streamable HTTP + a bearer token at:

https://test-farm-17d99.web.app/mcp Authorization: Bearer

Tools

• run_firmware_test — flashes the given firmware artifact onto a real board of the requested board_type and waits for a structured result (pass/fail, serial log excerpt, crash/reset info, timing). Every response includes live queue info (position, boards available, estimated wait) so an agent can decide whether to wait or come back later.
• get_upload_url — returns a short-lived signed URL to upload a firmware binary to before calling run_firmware_test.
• search_firmware_examples — searches a curated knowledge base of reference examples, known issues, and pinout/datasheet links for a given board type.

Currently available boards

heltec_wireless_tracker, arduino_giga_r1, xiao_nrf52840_plus, arduino_nicla_voice, arduino_nano_33_ble, adafruit_feather_esp32_v2, seeed_grove_vision_ai_v2, raspberrypi_pico

More board types are defined in the schema for future hardware; a submission for a board_type with no physical board currently registered is rejected up front rather than left queued forever.

Pricing

Every account starts on a free tier (50 firmware runs/month). Paid and Enterprise tiers are unlimited — Enterprise additionally covers custom board types and custom motors/controllers/sensors outside the standard fleet. See the dashboard for current usage and to request a tier change.
