@fusedashlabs/ui9000-workspace

MCP server with one tool, show_workspace. Give it a table and a question. It returns a chart the host can draw. The cells stay on the server. The result is a chart spec plus a signed data link, not the rows.

npm: @fusedashlabs/ui9000-workspace

What it does

show_workspace reads one table, classifies the columns, and draws one chart.

• When TYPESAFE_API_KEY is set, Jev chooses a class from the columns, then a chart inside that class. The result says why.

• A named chart in that class is the one drawn.

• A named chart in another class returns awaitingUser. Nothing is drawn. suggestion is the chart Jev would draw. The next call passes that chart as requestedChart with the same datasetId.

• A named chart this server cannot draw returns awaitingUser and does not draw a substitute.

• If Jev is unset, unreachable, or does not choose, the server picks a chart from the table.

The tool call must not include the table cells as data, rows, points, or series.

Connect

Node.js 20 or newer for the npx install. Jev is optional. Without TYPESAFE_API_KEY the server still draws a chart. Put the key only in the env block below. Do not commit it.

On connect the server returns instructions for Cursor, Claude Desktop, and Claude.ai. The host puts that text in context before it picks a tool: for a table or a chart, call show_workspace and do not draw with the chat's built-in chart tools. Those other tools stay available. A host that ignores server instructions can still use them.

Cursor

~/.cursor/mcp.json:

{
  "mcpServers": {
    "UI9000-Workspace": {
      "command": "npx",
      "args": ["-y", "@fusedashlabs/ui9000-workspace"],
      "env": {
        "TYPESAFE_API_KEY": "your-typesafe-key"
      }
    }
  }
}

Restart Cursor after saving.

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "UI9000-Workspace": {
      "command": "npx",
      "args": ["-y", "@fusedashlabs/ui9000-workspace"],
      "env": {
        "TYPESAFE_API_KEY": "your-typesafe-key"
      }
    }
  }
}

Claude.ai

Claude on the web cannot run npx. Add a custom connector:

1. Customize → Connectors → Add custom connector

2. Name: UI9000-Workspace

3. URL: https://mcp.ui9000.com/workspace/mcp

Enable the connector in the chat. This hosted server accepts csv or datasetId. It does not accept url or path. The Jev key is not part of this connector. Use the npx install above when you want to pass TYPESAFE_API_KEY.

How to call show_workspace

intent is required. It is the question, not a chart name.

Pass one source:

Optional:

Keep datasetId from the result for the next chart on the same table.
