Best Data & analytics resources for vibe coders

Updated 19/10/2026

This guide is for vibe coders who want an AI agent to work with data without writing everything by hand. You might need a spreadsheet cleaned up, a chart drawn, a notebook run, or market numbers pulled in.

How to choose

  • Start with the file or data you already have. Excel file: excel-mcp-server. CSV for a paper figure: scientific-plotting-skill. Public data from France: datagouv-mcp.
  • Prefer the safe label. Some tools here, like flint-chart, lieflat-charts and tradingview-mcp, are marked caution. Read their pages before installing.
  • Check setup needs. Finance servers may need data-source access, and intermediate tools usually need a working local environment such as Jupyter or a chart service.
  • Do not rely on finance tools alone for investment decisions. They supply data and analysis, not advice.

FAQ

Do I need Microsoft Excel to let an agent edit spreadsheets?

Not with excel-mcp-server, which works on workbooks without Excel installed. mcp-server-excel automates real Microsoft Excel, so it is meant for features like Power Query, DAX and VBA.

Which resource is easiest for a first chart?

For research-style figures, scientific-plotting-skill is a safe beginner skill. For many chart types through MCP, try mcp-server-chart, which is safe but intermediate.

Are there tools that avoid paid API keys?

world-intel-mcp says it does not require paid API keys. For the others, check each resource page for what it needs.
