MCP bridge for Tesserae Studio: author e-ink widgets with an AI agent.

tesserae-studio-mcp

Part of the Tesserae Studio repo (packages/tesserae-studio-mcp), so the bridge stays in lockstep with the Studio API it wraps. Published to PyPI as tesserae-studio-mcp.

The MCP bridge for Tesserae Studio. It lets an AI agent (Claude Code, Claude Desktop, or any MCP client) author Tesserae widgets end to end: scaffold a widget, edit its files, lint it, mine a data schema, register it to a running Tesserae, and render it, all through a running Studio server.

This is a thin stdio client. It talks to your Studio server over its local REST API (STUDIO_URL), so the linting, mining, registering, and rendering all run in your own Studio, which in turn drives your Tesserae.

scaffold_widget → write_file → lint_widget → register_widget → faithful_render → mine_data_schema

Prerequisites

A running Tesserae Studio server (it serves the API this bridge calls, and its web UI). See the Studio README for how to run it. Studio in turn connects to a Tesserae for live data and faithful (e-ink) render.

Install

Run this on the machine where your agent runs, which may differ from where Studio runs.

pip install tesserae-studio-mcp

or from source:

pip install "git+https://github.com/dmellok/tesserae-studio#subdirectory=packages/tesserae-studio-mcp"

Either gives you the tesserae-studio-mcp command.

Configure your agent

Point your MCP client at tesserae-studio-mcp. Example (Claude Desktop / Claude Code mcpServers config):

{
  "mcpServers": {
    "tesserae-studio": {
      "command": "tesserae-studio-mcp",
      "env": { "STUDIO_URL": "http://localhost:8770" }
    }
  }
}

Claude Code one-liner:

claude mcp add tesserae-studio -e STUDIO_URL=http://localhost:8770 -- tesserae-studio-mcp

• STUDIO_URL — where your Studio server is reachable (default http://localhost:8770). For a remote / Home Assistant Studio, use its LAN address, e.g. http://192.168.1.50:8770.

The build loop and the widget contract rules are sent to the agent automatically at handshake (FastMCP instructions), so you don't paste a prompt.

Run without installing

From a clone:

pip install mcp httpx
STUDIO_URL=http://localhost:8770 python -m tesserae_studio_mcp
