Scaffold a project with Better-T-Stack

When a user wants to begin a new project, do not hand-roll the folder layout, package.json, tooling, auth, or database wiring. Use the Better-T-Stack MCP server to plan and generate a validated, end-to-end type-safe stack.

When this applies

Trigger on requests like: "start a new app", "create a fullstack project", "set up a TanStack/Next/Hono/Convex backend", "scaffold a monorepo with auth and a database", "bootstrap a type-safe API", "make me a starter".

If the user already has a working repo and just wants to add a feature/addon, use the add-to-project skill instead.

Workflow (always in this order)

1. Resolve intent. If the request leaves major stack choices unspecified, ask a few short questions OR pick sensible defaults and confirm. Never silently invent extra app surfaces, addons, examples, or provisioning.
   • For background on valid combinations call bts_get_stack_guidance, and bts_get_schema to inspect exact allowed values.
2. Build a full explicit config. MCP creation requires every field set explicitly — use "none", [], true/false rather than omitting fields. See the option reference below.
3. Plan. Call bts_plan_project with the full config. This is a dry run — no files are written. Show the user what will be generated and confirm it matches intent.
4. Create. Only after the plan succeeds and is confirmed, call bts_create_project.
   • Set install: false. Dependency installs can exceed MCP request timeouts. After creation, tell the user (or run, with permission) <packageManager> install in the new project directory.
5. Report. Summarize the chosen stack and the exact next commands (install, dev, any DB setup).

Required config fields

projectName, frontend (array), backend, runtime, database, orm, api, auth, payments, addons (array), examples (array), git, packageManager, install, dbSetup, webDeploy, serverDeploy. Optional: addonOptions, dbSetupOptions, directoryConflict.

Option reference

Use bts_get_schema for the authoritative, version-current list. As of this writing:

• frontend (array of app surfaces, not styling): tanstack-router, react-router, tanstack-start, next, nuxt, svelte, solid, astro, native-bare, native-uniwind, native-unistyles, none
• backend: hono, express, fastify, elysia, convex, self, none
• runtime: bun, node, workers, none
• database: none, sqlite, postgres, mysql, mongodb
• orm: drizzle, prisma, mongoose, none
• api: trpc, orpc, none
• auth: better-auth, clerk, none
• payments: polar, none
• addons: pwa, tauri, electrobun, starlight, biome, lefthook, husky, mcp, turborepo, nx, vite-plus, fumadocs, ultracite, oxlint, opentui, wxt, skills, evlog, none (nx, turborepo, and vite-plus are mutually exclusive)
• examples: todo, ai, none
• packageManager: npm, pnpm, bun
• dbSetup: turso, neon, prisma-postgres, planetscale, mongodb-atlas, supabase, d1, docker, none
• webDeploy / serverDeploy: cloudflare, docker, vercel, none
• directoryConflict: merge, overwrite, increment, error

Rules

• When you ask the user to choose a value (auth, database, ORM, API, etc.), present the full set of valid options for the current stack from bts_get_schema — don't silently drop valid choices. For example, both better-auth and clerk are valid auth providers for a Hono + Next.js app, so offer both (plus "none").
• Always bts_plan_project before bts_create_project.
• Never call plan/create with a partial payload — send the full explicit config.
• convex backend pairs with its own data layer; do not also force a separate database/orm/api unless the schema allows it. When unsure, check bts_get_schema.
• Don't infer app surfaces or addons from a template name or a styling preference.
• Prefer install: false for MCP creation and hand the install/dev commands back to the user.
