FAQ — Data Analyst Loadout
What is the Data Analyst Loadout?
Query Postgres or BigQuery in plain English, drop the result into Excel for a chart, and document what you found in Notion. The full ad-hoc analysis loop in one chat. It includes 4 MCP servers: Postgres MCP Server, BigQuery MCP, Excel MCP, Notion MCP Server.
Does this loadout work with Cursor and Windsurf?
Yes. The config block above is one JSON object that drops into Claude Desktop's, Cursor's, or Windsurf's MCP config. Each client uses the same mcpServers schema; only the file path differs.
How long does setup take?
About 3 minutes the first time: copy the config, paste it into your client's MCP configuration file, replace placeholder API keys with your own, and restart the client.
Can I customise this loadout?
Yes. Use the Lite version if you want fewer servers, or the Heavy version to add 2 more for advanced workflows. You can also remove any individual server by deleting its entry from the JSON.
How much does it cost?
Loadout itself is free. Most listed servers are open-source and free to run. Servers that talk to paid SaaS (Stripe, SendGrid, Linear, etc.) follow that vendor's pricing.
When was this loadout last verified?
Last verified on 2026-04-24. We re-test featured loadouts at least monthly and update the config when MCP servers ship breaking changes.
