Prisma ORM v6.6.0: MCP Server for Prisma Postgres

Prisma Postgres is the first serverless database without cold starts. Designed for optimal efficiency and high performance, it's the perfect database to be used alongside AI tools like Cursor, Windsurf, Lovable or co.dev.

In the v6.6.0 ORM release, we added a command to start a Prisma MCP server that you can integrate in your AI development environment. Thanks to that MCP server, you can now:

  • tell your AI agent to create new DB instances
  • design your data model
  • chat through a database migration

… and much more.

To get started, add this snippet to the MCP configuration of your favorite AI tool and get started:

{
  "mcpServers": {
    "Prisma": {
      "command": "npx",
      "args": ["-y", "prisma", "mcp"]
    }
  }
}

🚀 Prisma ORM 6.6.0

Prisma ORM v6.6.0 comes packed with amazing features:

A modern and flexible prisma-client generator with ESM support (Early Access)

In v6.6.0, we introduced a new prisma-client generator that's more flexible, comes with ESM support and removes any magic behaviours that may cause friction with the current prisma-client-js generator.

Note: The prisma-client generator is currently in Early Access and will likely have some breaking changes in the next releases.

Here are the main differences:

  • Requires an output path; no “magic” generation into node_modules any more
  • Supports ESM and CommonJS via the moduleFormat field
  • Outputs plain TypeScript that's bundled just like the rest of your application code

Here's how you can use the new prisma-client generator in your Prisma schema:

// prisma/schema.prisma
generator client {
  provider     = "prisma-client"           // no `-js` at the end
  output       = "../src/generated/prisma" // `output` is required
  moduleFormat = "esm"                     // or `"cjs"` for CommonJS
}

Cloudflare D1 & Turso/LibSQL migrations (Early Access)

Cloudflare D1 and Turso are popular database providers that are both based on SQLite. While you can query them using the respective driver adapter for D1 or Turso, previous versions of Prisma ORM weren't able to make schema changes against these databases.

With the v6.6.0 release, we're sharing the first Early Access version of native D1 migration support for the following commands:

  • prisma db push: Updates the schema of the remote database based on your Prisma schema
  • prisma db pull: Introspects the schema of the remote database and updates your local Prisma schema
  • prisma migrate diff: Outputs the difference between the schema of the remote database and your local Prisma schema

📚 Learn more in the docs:

😎 npx prisma init --prompt "An encyclopedia for cats"

You can now pass a --prompt option to the prisma init command to have it scaffold a Prisma schema for you and deploy it to a fresh Prisma Postgres instance:

npx prisma init --prompt "An encyclopedia for cats"

For everyone, following social media trends, we also created an alias called --vibe for you 😉

npx prisma init --vibe "Cat meme generator"
