- Use strict TypeScript.
- Prefer server components unless interactivity is required.
- Keep client components small and colocated with their route.
- Run npm run lint and npm run build before merging.
Save this as .cursor/rules/next-js-app-router-standards.mdcHow to convert Cursor rules to MDC
- Paste legacy rules. Paste your old .cursorrules text into the converter.
- Name the rule. Enter a short description that tells Cursor when the rule is useful.
- Set file globs. Add matching globs such as src/**/*.{ts,tsx} for scoped project rules.
- Copy the MDC file. Copy or download the generated .mdc output and save it under .cursor/rules.
Browser-only conversion
Your pasted rules stay in the page session. The converter only formats text and prepares copy-ready Markdown.
Migration-friendly output
Bullet cleanup removes old list markers while preserving the actual project guidance your team already wrote.
Cursor MDC rules FAQ
What is a Cursor MDC rules converter?
A Cursor MDC rules converter turns old .cursorrules guidance into the newer .cursor/rules/*.mdc format with frontmatter for description, file globs, and alwaysApply.
Where should I save a Cursor .mdc rule file?
Save project rules in .cursor/rules with a .mdc extension. Cursor reads those files and applies them based on their frontmatter and matching globs.
Should alwaysApply be true or false?
Use alwaysApply true only for rules that apply to every prompt and every file. Use false with globs for stack-specific or folder-specific guidance.
Does this converter upload my rules?
No. The converter runs in your browser and does not send your pasted rules to Tornic or any third-party service.
