Setup guide

Install Nullcost fast.

The easiest path is to let your coding agent do the setup, or run the local commands below if you want the manual route.

Installation steps

Recommended for most users
01

Ask your coding agent

Easiest

Copy this prompt into Codex, Claude Code, Cursor, or another agent with terminal access.

Install the Nullcost catalog, seed the database, and start the MCP server.
Caveats: Your agent needs terminal access. It will run npm commands and local Supabase setup, so use this only in a repo and machine you trust.
Or do it manually
02

Start the local data

Gives Nullcost a real catalog to query.

npm run supabase:start
npm run db:seed
03

Start website and API

The site and MCP both read the same local API.

npm run dev
04

Start the MCP server

This is the part your coding app talks to.

npm run mcp:catalog

Manual config
