Prisma MCP Server

What is Prisma MCP Server?

It provides a Model Context Protocol (MCP) server that acts as an interface to a database managed by Prisma ORM, allowing MCP-compatible clients (like AI assistants) to query resources and execute CRUD tools on Prisma models.

How to use Prisma MCP Server?

Install cadcamfun-db-mcp-server and @prisma/client, set the DATABASE_URL environment variable (and optionally TRANSPORT_TYPE, PORT), generate Prisma Client (npx prisma generate), then call createPrismaMcpServer() and server.start() with the desired transport type (stdio or sse). Connect your MCP client to the running server.
