Add MCP App visualization server for analyzing-data skill#155
Conversation
Adds a Prefab-based MCP App server that renders interactive charts and tables inline in Cursor when the user requests visual output from the analyzing-data skill. - New `viz_mcp.py` server with `render_chart` and `render_table` tools using Prefab UI (BarChart, LineChart, DataTable with tabs, search, sort, pagination) - Register `analytics-viz` MCP server in both `.claude-plugin/plugin.json` and `.cursor-plugin/plugin.json` - Update SKILL.md with visualization workflow guidance

You mention a Claude plugin too in the PR description. Do you have that update locally to push?

Already done — removed the mcpServers block from .claude-plugin/plugin.json since MCP Apps are Cursor-only. PR description updated too.

Claude Code doesn't supprot MCP Apps unfortunately. And Claude CoWork is sandboxed by default to allow a lot of what we use
- Simplify __main__ block — both branches were identical - Reword SKILL.md to check tool list instead of server name
