Pricing

The free tier is not a demo. It is the part that makes an agent competent in your codebase, and it stays free. The paid tiers are for when you want to look at the architecture rather than only ask it questions.

How the paid tiers work

  1. 01You subscribe and get a licence key, shown on your account page and kept current there.
  2. 02Install the add-on like any package: npm install --save-dev nextjs-mcp-architecture-pro. No token, no registry — it is public on npm, and without the key it does nothing.
  3. 03Put the key in the NEXTJS_MCP_LICENSE environment variable, or in ~/.config/nextjs-mcp/license. The MCP server registers the extra tools on its next start; nothing in your MCP configuration changes.
  4. 04If you cancel, the paid tools stop within about a week and the free tier carries on. There is a grace period, so a failed renewal does not interrupt you mid-task.

A note on billing

Payments are handled by a merchant of record, which means VAT and sales tax are collected and remitted for you and your invoice comes from them. Cancel from the same portal at any time; there is no annual commitment and no seat counting.
