Official serverRemoteDatabases

1. Add the server

Run in your terminal

codex mcp add neon --url https://mcp.neon.tech/mcp

2. Sign in

Run codex mcp login <name> to complete OAuth for a remote server. Neon is hosted by Neon, so there is nothing to install or keep updated.

3. Try it

Ask Codex for something Neon can do. Create and manage Neon Postgres projects, branches and databases, and run SQL. Approve the first tool call and check the result before allowing write actions automatically.

· Each server is a [mcp_servers.<name>] table in config.toml.
· Use enabled_tools or disabled_tools to keep the tool list short.
