mcp-svd
by pkt-lab
Allows querying official ARM CMSIS SVD hardware register definitions to retrieve precise register names, bit positions, and addresses for supported microcontrollers.
Provides access to the Raspberry Pi RP2040's hardware register definitions through bundled SVD files, enabling detailed searches for its peripherals and registers.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-svdLook up the bitfields for the GPIOA MODER register in svd/STM32F411.svd"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-svd
An MCP (Model Context Protocol) server that exposes ARM CMSIS SVD hardware register definitions to AI coding assistants. Instead of hallucinating register names, bit positions, and addresses, your AI assistant can query the exact definitions straight from the official SVD file for your microcontroller.
Install
From GitHub (no npm needed):
npm install github:pkt-lab/mcp-svdOr clone and build manually:
git clone https://github.com/pkt-lab/mcp-svd
cd mcp-svd
npm install && npm run buildRelated MCP server: stm32-mcp-docs
