VS Code MCP Setup

If you want the true inline chat experience in VS Code, follow:

VS_CODE_MCP_SETUP.md

Run As An MCP Server

python server.py

This server now builds on panel-live-server, so compatible MCP clients can render create_plot and update_plot inline in the chat pane instead of only returning a URL. For reliability, the structured tools use a lightweight HoloViews rendering path for single plots, while interactive widget apps can be rendered through show or interactive_sine_wave.

Run The Local Demo

python test_local.py

This simulates MCP tool calls locally, prints the returned payload, and opens the fallback browser URLs. It also includes an interactive HoloViews sine-wave app with sliders. Inline rendering only happens inside a compatible MCP client UI. Keep the terminal open while viewing the demo. The /feed endpoint is not the visualization; open the returned /view?id=... URL instead.

Testing Example

Example create_plot input:

{
  "data": [
    {"week": 1, "sales": 120},
    {"week": 2, "sales": 135},
    {"week": 3, "sales": 128},
    {"week": 4, "sales": 150},
    {"week": 5, "sales": 162}
  ],
  "plot_type": "scatter",
  "x": "week",
  "y": "sales"
}

Example update_plot input:

{
  "plot_id": "<returned plot_id>",
  "data": [
    {"week": 1, "sales": 120},
    {"week": 2, "sales": 135},
    {"week": 3, "sales": 128},
    {"week": 4, "sales": 150},
    {"week": 5, "sales": 162},
    {"week": 6, "sales": 174},
    {"week": 7, "sales": 181}
  ],
  "plot_type": "line"
}

When you run python test_local.py, it uses this exact scenario and prints the MCP payloads returned by both tools.

Interactive Chat Example

When the user wants a plot rendered inline in chat with widget controls, call:

• interactive_sine_wave

This tool returns a Panel app backed by HoloViews and includes sliders for:

• amplitude
• frequency
• phase

For custom widget-driven apps, use:

• show

Structured Plot Tools

• create_plot
• update_plot
• list_plot_types

Inherited panel-live-server Tools

• show
• validate
• list_packages

Supported Plot Types

• scatter
• line
• bar
