## What this server does

Neon is serverless Postgres with instant branching; this official server lets the assistant use that branching as a safety net. List projects, run SQL, describe schemas, and create branches. The standout workflow is migrations: the server stages schema changes on a temporary branch first, so the model can verify a migration in isolation before you apply it to your main branch. That makes 'let the AI evolve my schema' far less terrifying than running DDL straight at production.

## Tools included

-   list\_projects
    
    List your Neon projects.
    
-   run\_sql
    
    Run a SQL statement against a project's database.
    
-   create\_branch
    
    Create a database branch.
    
-   describe\_table\_schema
    
    Describe a table's schema.
    
-   prepare\_database\_migration
    
    Stage a schema migration on a temporary branch.
    

The authoritative list comes from the server's tools/list at runtime. This catalog entry may lag the upstream until the next ToolPiper release.

{
  "mcpServers": {
    "neon": {
      "command": "npx",
      "args": [
        "-y",
        "@neondatabase/mcp-server-neon",
        "start",
        "${NEON_API_KEY}"
      ]
    }
  }
}
```

## Example prompts

-   "List my Neon projects and the databases in each."
    
    Copy
-   "Create a branch called ai-experiment and run a SELECT to check the users table."
    
    Copy
-   "Prepare a migration that adds a 'last\_login' timestamp column to users."
    
    Copy

## Security notes

The API key controls your Neon account: it can create branches, run SQL, and apply migrations. Treat it as a credential and rotate it from the Neon console if it leaks. The branch-first migration flow limits blast radius, but run\_sql can still modify the branch it targets. Point experiments at a branch, not your production database.
