Briefing
The seven vendors are Arm, Nordic, Analog Devices, Espressif, Microchip, Silicon Labs and TI. Frassinelli sorts their servers by what they do: three serve documentation only, three drive the toolchain, four reach live debug or capture, two serve fleet data and none runs firmware in simulation.
He writes that NXP put its MCP work into upstream Zephyr rather than a server of its own. He also names two projects often called MCP servers that are not, stm32-substrate and esp-agentic-dev. Chiplab, Veecle's product, is a hosted MCP server that runs firmware on virtual Cortex-M parts, and the post says so.
