neon-postgres is a Codex plugin developed by Neon that lets an AI assistant manage Neon Serverless Postgres projects and databases via a bundled agent skill and the Neon MCP Server. According to the plugin.json manifest (version 1.0.3, Apache-2.0), the skill includes guides on connection methods, branching, autoscaling, and Neon Auth. Per the Neon MCP Server documentation, the server implements the Model Context Protocol so an assistant can create branches, run schema changes, execute SQL, and configure Neon Auth or the Data API, with setup via npx neon@latest init or a config generator supporting OAuth or API key authentication. The same documentation warns that the MCP server grants broad database management capabilities and recommends using it only for development and testing, never against production databases, while always reviewing and authorizing LLM-requested actions. Access can be limited further with read-only mode, project-scoped mode, or category filtering of tools.

Overview

According to the plugin's homepage and author metadata, Neon is a Serverless Postgres database service; this plugin surfaces Neon's project and database management features, along with the Neon MCP Server, to a Codex AI agent.
