Medius Documentation
MCP serverDev toolsCommunity-maintained documentation for Medius, covering the binary control format, how Medius devices behave, and the medius Rust library. Once added, your AI can answer Medius questions on its own, from how commands are encoded to how devices respond. Useful when you are building something that talks to Medius devices or writing code with the medius Rust library.

Add the docs, then ask your AI something specific, like how a Medius command is encoded or how a device responds. The full source is available at github.com/k4hvh/medius-docs.
What your AI can do with it
- Answer questions about how Medius devices behave
- Look up the binary control format and command details
- Explain how to use the medius Rust library
- Help write Rust code that uses the medius library
- Reference the documentation when debugging device communication
Install Medius Documentation
The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.
Claude Code
claude mcp add --transport http --scope user medius-documentation 'https://medius.k4tech.net/mcp'Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://medius.k4tech.net/mcpAdd a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=medius-documentation&config=eyJ1cmwiOiJodHRwczovL21lZGl1cy5rNHRlY2gubmV0L21jcCJ9Open the link and Cursor adds the server at that address.
ChatGPT
https://medius.k4tech.net/mcpIn Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add medius-documentation --url 'https://medius.k4tech.net/mcp'Run it once, then sign in with codex mcp login medius-documentation if the server asks for an account.
From the project's README
As published by k4hvh/medius-docs in README.md.
Documentation site for Medius: the input-passthrough firmware, its binary control protocol, and the medius Rust library.
Built with SolidJS and MidnightUI.
Sections
| Section | What |
|---|---|
| Native API | Binary control protocol and box behaviour: hardware, transport, frame format, injection model, every command (opcodes 0x01-0x1E). |
| Rust Library | medius crate reference: connecting, command bindings, keepalive, reconnect, and the async / mock / tracing features. |
| Bindings | C ABI and Python bindings over the crate. |
| Dashboard | In-browser box dashboard: connect, device info, firmware update, recovery, device log. |
| AI Access | Per-page Markdown twins, llms.txt, and the MCP server. |
Development
Prerequisites
Setup
bun install
Dev server
bun run dev
Open http://localhost:3000.
Build
bun run build
Output: dist/.
Tech stack
| Tool | Role |
|---|---|
| SolidJS | Reactive UI framework |
| @solidjs/router | Client-side routing |
| Vite | Build tool |
| Bun | Runtime and package manager |
| MidnightUI | Component library |
| solid-icons | Icons |
Deployment
CI builds the app and a multi-arch container on every push to main and publishes it to
ghcr.io/k4hvh/medius-docs. Run it:
docker run --rm -p 3000:3000 ghcr.io/k4hvh/medius-docs:latest
docker-compose.yml runs the same image. The container builds with Bun and serves dist/
on port 3000.
