Is there an official Postgres MCP server?

The Postgres reference server from the MCP project is archived. Supabase and Neon run official remote servers for their hosted Postgres, and DBHub is a maintained community option.

Which database MCP servers have a read-only mode?

Supabase (read_only=true URL parameter) and MongoDB (--readOnly flag) document one; the archived Postgres reference server is read-only by design. For others, use a read-only database user.

MCP servers for databases

Connecting an agent to a database is the most useful and most dangerous MCP setup. Here is what each server needs, and which ones document a read-only mode.

§1At a glance

Server	Runs	Auth	Read-only option
Supabase	Remote	OAuth	Yes — `read_only=true` URL parameter, scoped by `project_ref`
Neon	Remote	OAuth or Neon API key	Not in our verified snippet — see README
PostgreSQL (reference, archived)	Local (npx)	Connection string	Read-only by design (archived reference server)
DBHub	Local (npx, HTTP)	Database DSN	Use a read-only DB user (Claude Code docs example)
MongoDB	Local (npx)	Connection string or Atlas service account	Yes — `--readOnly` flag
SQLite (reference, archived)	Local	None (local file)	No — exposes write_query and create_table
Redis	Local	Redis URL / credentials	See README
ClickHouse	Local (uvx)	ClickHouse user + password	See README

§2Postgres options

There are three Postgres paths in the index. Supabase and Neon are vendor-run remote servers that sign you in with OAuth. PostgreSQL (reference, archived) is the original reference server — read-only and schema-aware, but archived, so it receives no updates. DBHub is a maintained community server that speaks Postgres, MySQL, SQL Server and SQLite through one DSN.

Supabase — scoped and read-only (from Supabase docs)

DBHub in Claude Code with a read-only user (from Anthropic's docs)

claude mcp add --transport stdio db -- npx -y @bytebase/dbhub \
  --dsn "postgresql://readonly:pass@prod.db.com:5432/analytics"

§3Rules worth following

Connect with a database user that has only the privileges the task needs; read-only for analysis.
Prefer a branch, replica or staging database over production.
Keep credentials in environment variables, not in a committed config file.
Leave tool approval on for anything that writes.
