"mcpServers": {
"neondatabase-mcp-server-neon": {
"command": "npx",
"args": [
"-y",
"neonctl@latest"
],
"env": {
"NEON_API_KEY": "<YOUR_NEON_API_KEY>",
"CLIENT_SECRET": "<YOUR_CLIENT_SECRET>",
"COOKIE_SECRET": "<YOUR_COOKIE_SECRET>"
}
}
}
}Add this to your Claude Desktop config file. Find it at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.
What this does
neondatabase/mcp-server-neon exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation. That makes it useful when you want Claude to reach into your databases without copy-pasting context every turn.
Requirements
This server needs the following environment variables to be set before it can run:
NEON_API_KEY CLIENT_SECRET COOKIE_SECRET
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Common use cases
- •Query structured data without writing SQL by hand
- •Let Claude read table schemas before answering data questions
- •Run read-only operational reports or sanity checks during incidents
