Neon Serverless Postgres

Guide the user through any Neon-related task: setup, connections, branching, and advanced features. Deliver a working Neon connection, a completed feature configuration, or a specific answer from the official Neon docs.

Neon is a serverless Postgres platform that separates compute and storage to offer autoscaling, branching, instant restore, and scale-to-zero. It's fully compatible with Postgres and works with any language, framework, or ORM that supports Postgres.

Usage

Use this skill when the user needs a current, practical Neon answer that ends in one of three outcomes:

• a working Neon connection string and environment setup
• a concrete Neon feature configuration such as branching, pooling, autoscaling, or auth
• an official-docs-grounded explanation of how a Neon capability behaves

Neon Documentation

The Neon documentation is the source of truth for all Neon-related information. Always verify claims against the official docs before responding. Neon features and APIs evolve, so prefer fetching current docs over relying on training data.

Fetching Docs as Markdown

Any Neon doc page can be fetched as markdown in two ways:

1. Append .md to the URL (simplest): https://neon.com/docs/introduction/branching.md
2. Request text/markdown on the standard URL: curl -H "Accept: text/markdown" https://neon.com/docs/introduction/branching

Both return the same markdown content. Use whichever method your tools support.

Finding the Right Page

The docs index lists every available page with its URL and a short description:

https://neon.com/docs/llms.txt

Common doc URLs are organized in the topic links below. If you need a page not listed here, search the docs index: https://neon.com/docs/llms.txt. Don't guess URLs.

What Is Neon

Use this for architecture explanations and terminology (organizations, projects, branches, endpoints) before giving implementation advice.

Link: https://neon.com/docs/introduction/architecture-overview.md

Getting Started

Use this section when guiding a user through first-time Neon setup.

Check Status Quo

Before starting setup, inspect the user's codebase and environment:

• Existing database connection code
• Existing Neon MCP server or Neon CLI configuration
• Existence of a .env file and DATABASE_URL environment variable
• Existing ORM (Prisma, Drizzle, TypeORM) configuration

Self-Driving Setup With Neon's CLI or MCP Server

Offer to inspect existing connected Neon projects or create new ones using the Neon CLI or MCP server. If neither is set up yet, run init with the --agent flag. Use npx -y to skip the package install prompt. Auth is handled automatically. If the user is not logged in, it opens their browser for OAuth and waits for completion before proceeding.

npx -y neonctl@latest init --agent <agent-name>

Supported --agent values: cursor, copilot, claude, claude-desktop, codex, opencode, cline, gemini-cli, goose, zed.

This installs the Neon extension (for Cursor/VS Code) or MCP server (for other agents), creates an API key, and adds the neon-postgres agent skill to the project.

If init is not suitable, the individual steps can be run non-interactively:

• Extension: cursor --install-extension databricks.neon-local-connect
• MCP server: npx -y add-mcp https://mcp.neon.tech/mcp -g -n Neon -y -a <agent-name>
• Agent skill: npx skills add neondatabase/agent-skills --skill neon-postgres --agent <agent-name> -y

For full CLI installation options, see https://neon.com/docs/reference/cli-install.md

Setup Flow

1. Select Organization and Project

Use MCP server or CLI to list organizations and projects. Let the user select an existing project or create a new one.

2. Get Connection String

Use MCP server or CLI to get the connection string. Store it in .env as DATABASE_URL. Read the file first before modifying to avoid overwriting existing values.

3. Pick Connection Method & Driver

Refer to the connection methods guide to pick the correct driver based on deployment platform: https://neon.com/docs/connect/choose-connection.md

4. User Authentication with Neon Auth (if needed)

Skip for CLI tools, scripts, or apps without user accounts. If the app needs auth: use MCP server provision_neon_auth tool, then see the auth overview (https://neon.com/docs/auth/overview.md) for setup. For auth + database queries, see the JavaScript SDK reference (https://neon.com/docs/reference/javascript-sdk.md).

5. ORM Setup (optional)

Check for existing ORM (Prisma, Drizzle, TypeORM). If none, ask if they want one. For Drizzle integration, see https://neon.com/docs/guides/drizzle.md.

6. Schema Setup

• Check for existing migration files or ORM schemas
• If none: offer to create an example schema or design one together

Resume Support

If resuming setup, check what's already configured (MCP connection, .env with DATABASE_URL, dependencies, schema) and continue from the next incomplete step.

Security Reminders

Remind users to use environment variables for credentials, never commit connection strings, and use least-privilege database roles.

Connection Methods & Drivers

Use this when you need to pick the correct transport and driver based on runtime constraints (TCP, HTTP, WebSocket, edge, serverless, long-running).

Link: https://neon.com/docs/connect/choose-connection.md

Serverless Driver

Use this for @neondatabase/serverless patterns, including HTTP queries, WebSocket transactions, and runtime-specific optimizations.

Link: https://neon.com/docs/serverless/serverless-driver.md

Neon JS SDK

Use this for combined Neon Auth + Data API workflows with PostgREST-style querying and typed client setup.

Link: https://neon.com/docs/reference/javascript-sdk.md

Developer Tools

Use this for local development enablement with npx -y neonctl@latest init --agent <agent-name>, VSCode extension setup, and Neon MCP server configuration.

Tool	URL
CLI Init Command	https://neon.com/docs/reference/cli-init.md
VSCode Extension	https://neon.com/docs/local/vscode-extension.md
MCP Server	https://neon.com/docs/ai/neon-mcp-server.md
Neon CLI	https://neon.com/docs/reference/neon-cli.md

Neon CLI

Use this for terminal-first workflows, scripts, and CI/CD automation with neonctl.

Link: https://neon.com/docs/reference/neon-cli.md

Neon Admin API

The Neon Admin API can be used to manage Neon resources programmatically. It is used behind the scenes by the Neon CLI and MCP server, but can also be used directly for more complex automation workflows or when embedding Neon in other applications.

Neon REST API

Use this for direct HTTP automation, endpoint-level control, API key auth, rate-limit handling, and operation polling.

Link: https://neon.com/docs/reference/api-reference.md

Neon TypeScript SDK

Use this when implementing typed programmatic control of Neon resources in TypeScript via @neondatabase/api-client.

Link: https://neon.com/docs/reference/typescript-sdk.md

Neon Python SDK

Use this when implementing programmatic Neon management in Python with the neon-api package.

Link: https://neon.com/docs/reference/python-sdk.md

Neon Auth

Use this for managed user authentication setup, UI components, auth methods, and Neon Auth integration pitfalls in Next.js and React apps.

Link: https://neon.com/docs/auth/overview.md

Neon Auth is also embedded in the Neon JS SDK. Depending on your use case, you may want to use the Neon JS SDK instead of Neon Auth alone. See https://neon.com/docs/connect/choose-connection.md for more details.

Branching

Use this when the user is planning isolated environments, schema migration testing, preview deployments, or branch lifecycle automation.

Key points:

• Branches are instant, copy-on-write clones (no full data copy).
• Each branch has its own compute endpoint.
• Use the neonctl CLI or MCP server to create, inspect, and compare branches.

Link: https://neon.com/docs/introduction/branching.md

For detailed branch creation workflows (normal vs schema-only branches, reset-from-parent, CLI/MCP selection), use the neon-postgres-branches skill if available

Or fetch the full branching skill from the following URL:

https://neon.com/docs/ai/skills/neon-postgres-branches/SKILL.md

If this skill is not installed you can use the following command to install it:

npx skills add neondatabase/agent-skills --skill neon-postgres-branches

Autoscaling

Use this when the user needs compute to scale automatically with workload and wants guidance on CU sizing and runtime behavior.

Link: https://neon.com/docs/introduction/autoscaling.md

Scale to Zero

Use this when optimizing idle costs and discussing suspend/resume behavior, including cold-start trade-offs.

Key points:

• Idle computes suspend automatically (default 5 minutes, configurable) (unless disabled - launch & scale plan only)
• First query after suspend typically has a cold-start penalty (around hundreds of ms)
• Storage remains active while compute is suspended.

Link: https://neon.com/docs/introduction/scale-to-zero.md

Instant Restore

Use this when the user needs point-in-time recovery or wants to restore data state without traditional backup restore workflows.

Key points:

• History windows for instant restore depend on plan limits.
• Users can create branches from historical points-in-time.
• Time Travel queries can be used for historical inspection workflows.

Link: https://neon.com/docs/introduction/branch-restore.md

Read Replicas

Use this for read-heavy workloads where the user needs dedicated read-only compute without duplicating storage.

Key points:

• Replicas are read-only compute endpoints sharing the same storage.
• Creation is fast and scaling is independent from primary compute.
• Typical use cases: analytics, reporting, and read-heavy APIs.

Link: https://neon.com/docs/introduction/read-replicas.md

Connection Pooling

Use this when the user is in serverless or high-concurrency environments and needs safe, scalable Postgres connection management.

Key points:

• Neon pooling uses PgBouncer.
• Add -pooler to endpoint hostnames to use pooled connections.
• Pooling is especially important in serverless runtimes with bursty concurrency.

Link: https://neon.com/docs/connect/connection-pooling.md

IP Allow Lists

Use this when the user needs to restrict database access by trusted networks, IPs, or CIDR ranges.

Link: https://neon.com/docs/introduction/ip-allow.md

Logical Replication

Use this when integrating CDC pipelines, external Postgres sync, or replication-based data movement.

Key points:

• Neon supports native logical replication workflows.
• Useful for replicating to/from external Postgres systems.

Link: https://neon.com/docs/guides/logical-replication-guide.md

Common Patterns

Pattern: existing app already has Postgres

• inspect current ORM, driver, and .env usage first
• swap only the connection string and driver-specific config needed for Neon
• validate migrations and pooling behavior before changing any runtime code

Pattern: new project needs fastest Neon bootstrap

• initialize Neon tooling with neonctl or the MCP server first
• store DATABASE_URL in environment variables before adding ORM glue
• choose the simplest driver compatible with the target runtime

Pattern: preview or branch-based workflows

• create isolated branches for migrations and preview deployments
• verify each branch has the correct compute endpoint before testing
• document branch cleanup rules so temporary environments do not linger

Boundaries

• Do not invent Neon product behavior when a current docs page can answer it directly.
• Do not overwrite existing database credentials or .env values without first reading the file and preserving unrelated entries.
• Do not recommend a single driver or auth path blindly; choose based on runtime constraints, auth needs, and deployment model.
