@tablecharts/mcp-server

MCP server for TableCharts — turn tables (CSV, JSON, Notion, Google Sheets, Salesforce) into shareable interactive dashboards, directly from Claude, Cursor, VS Code, or any other MCP client.

Why

LLMs are great at producing structured data but terrible at producing real charts. This server gives any MCP-aware assistant a one-shot tool to convert tabular data into a hosted, embeddable dashboard with a public URL.

Install

npm i -g @tablecharts/mcp-server

Or run on demand with npx -y @tablecharts/mcp-server — no install needed.

Get an API key

1. Sign up at https://tablecharts.co
2. Open https://tablecharts.co/api-keys
3. Create a key starting with tc_live_…

Configure your MCP client
