What is Neon's 'Zero-Copy Branching' and how do I use it through the agent?

Zero-copy branching allows you to clone a multi-terabyte database instantly using Copy-on-Write (CoW). Use the `create_branch` tool by providing a parent branch ID. Your agent will trigger the backend to generate an isolated clone in milliseconds, perfect for running migrations or testing features against production-like data.

Can my agent retrieve the exact connection strings for my compute endpoints?

Yes. Use the `list_endpoints` tool with your Project ID. Your agent will retrieve the explicit hostnames (e.g., `ep-misty-water-123.aws.neon.tech`) used to actively ingest real query traffic to your serverless Postgres branches.

How do I check the storage consumption for a specific Neon branch?

The `get_branch` tool retrieves the deconstructed execution footprint of an individual branch. Your agent will report the storage limits and exact number of bytes consumed uniquely by that branch's data delta since it split from its parent.

About Neon (Serverless PostgreSQL) MCP Server

Connect your Neon account to any AI agent and take full control of your serverless PostgreSQL infrastructure, database branching, and project orchestration through natural conversation.

The OpenAI Agents SDK auto-discovers all 10 tools from Neon (Serverless PostgreSQL) through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Neon (Serverless PostgreSQL), another analyzes results, and a third generates reports, all orchestrated through Vinkius.

What you can do

Project Orchestration — List all managed serverless workspaces and retrieve detailed regional deployment metrics and regional Caps directly from your agent
Zero-Copy Branching — Instantly spawn brand new database branches (CoW) containing identical production schema duplicates for isolated feature testing or rapid CI/CD cycles
Compute Management — Discover and list explicit compute endpoints (e.g., ep-misty-water-123) to retrieve the exact connection strings required for your application drivers
Branch Audit — Inspect the execution footprint of specific branches, tracking storage deltas and timeline points (LSN) to understand exactly when a branch split from its parent
Database Inventory — Enumerate internal SQL database schemas and catalog namespaces mapped inherently to specific branches to guide your connection logic
Role Management — List and audit PostgreSQL user identities and credential roles capable of querying against specific bounded logical nodes securely
Resource Provisioning — Initialize fresh serverless workspaces or permanently wipe out entire database ecosystems with irreversible architectural commands

The Neon (Serverless PostgreSQL) MCP Server exposes 10 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
