title: Neon | Keycard
description: Serverless Postgres with branching and autoscaling
---

Manage Neon Postgres databases directly from your AI assistant. Create and manage database branches, run SQL queries, manage roles and permissions, and monitor database performance without leaving your coding environment.

Adding Neon provisions three things in your zone: an upstream resource pointing at `https://mcp.neon.tech/mcp` (kept inside Keycard), a Keycard MCP Gateway URL - the downstream resource - that you install in Cursor, Claude Code, or any MCP client, and a provider for token exchange with Neon’s OAuth issuer.

When your AI client makes a tool call, it sends a Keycard-issued access token to the gateway URL. Keycard’s STS exchanges that token for an upstream Neon token, the gateway calls the upstream MCP, and the response is proxied back. Your zone’s [identity provider](/admin/identity-providers/index.md), [access policies](/admin/access-policies/index.md), and audit log apply to every call - the upstream credential never leaves Keycard. Each call is recorded in the audit log with the user identity, the resource accessed, and the policy decision.

## Install

INSTALL

Add Neon to your zone and install the gateway URL into Cursor, Claude Code, or any MCP client.

1. **Open the catalog**

   In your zone’s [Keycard Console](https://console.keycard.ai), go to **Applications** → **Add Application** → **Explore MCP Servers**.

2. **Find and install Neon**

   Search for `Neon` in the catalog and click **Install**.

3. **Connect your development tool**
