ByteAsk Embedded MCP server

Lets your AI look up exact facts from embedded and firmware reference docs, with page citations.

ByteAsk Embedded MCP is a helper that connects your AI to a library of embedded and firmware reference documents. When your AI needs an exact register value, a Modbus function code, or a datasheet detail, it can look it up here instead of guessing. It is handy for anyone writing firmware, drivers, or protocol code.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to a service. This one connects your AI to ByteAsk Embedded Docs, a searchable collection of embedded and firmware reference material. Once connected, your AI can ask that collection for exact snippets when you need a real fact, not a guess.

What this MCP server does

You ask your AI a question about embedded or firmware details, like a register offset or a Modbus code. Your AI passes your question to this helper. The helper searches the ByteAsk document collection and finds the most relevant passages. It sends back the exact wording from the source, along with the document title and page number. If nothing matches well enough, it tells your AI there is no confident match, so your AI does not make something up.

Flow diagram: you ask your AI “What Modbus code writes multiple registers?”, the ByteAsk Embedded MCP server connects it to ByteAsk docs, and you get back quoted answer with page number.

What you can do with it

Look up Modbus function codes and register details
Find SunSpec points and IEEE 1547 thresholds
Check SCPI commands and MCU register offsets
Get verbatim snippets with page citations
Expand a result to see the full source section
Ask for a missing document to be added to the collection

Try asking your AI

“What Modbus function code writes multiple registers?”
“Find the SunSpec point for maximum output power”
“What is the SCPI command to read the output voltage?”
“Show me the register offset for the ADC control register on this MCU”

What it gives back to you

You get back short, quoted passages from the source documents. Each one shows the document title, the section and page number, and the exact wording. If nothing is found, you get a clear no match message instead of a made-up answer. You can also ask to expand a result to see the full section it came from.

Before you start

What you need

For the hosted version: nothing to install, just the endpoint URL
For the local version: Python 3.10 or newer and the uv tool
An MCP client like Claude Code, Codex, or Cursor

Good to know

The local version ships with only a few sample records, so for real work you want the hosted endpoint or your own document collection.

Install it with your AI

Add ByteAsk Embedded MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check ByteAsk Embedded MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
