# Best Postgres for AI apps

AI apps have a different database profile than traditional web apps. Requests burst unpredictably, inference runs at the edge, and agents increasingly need direct database access. Most managed Postgres services weren't designed with those patterns in mind.

## [Built-in connection pooling](#built-in-connection-pooling)

Serverless inference endpoints open a new database connection per invocation. At any meaningful load, that exhausts your Postgres connection limit fast. Prisma Postgres includes connection pooling by default, so there is no PgBouncer to configure and no sidecar to run. Your connection string already points to the pooler.

## [Edge-native connectivity](#edge-native-connectivity)

Standard Postgres TCP drivers don't work in Cloudflare Workers, Vercel Edge Functions, or Deno Deploy. Prisma Postgres ships `@prisma/ppg`, a serverless driver that connects over HTTP.

See [Serverless driver](/guides/database-serverless-driver) for setup.

## [pgvector for embeddings](#pgvector-for-embeddings)

Prisma Postgres supports the `pgvector` extension for storing and querying vector embeddings natively in Postgres. You can keep your embeddings alongside your application data without a separate vector store.

See [Postgres extensions](/guides/database-postgres-extensions) for how to enable it.

## [MCP server for agent workflows](#mcp-server-for-agent-workflows)

AI agents (Claude, Cursor, or custom) can connect to Prisma Postgres via the Prisma MCP server to introspect schemas, run queries, apply migrations, and manage environments, without raw SQL access.

See [Prisma MCP server](/guides/tools-integrations-ai-tools-mcp-server) for setup.
