Sequel CLI

Install PostgreSQL MCP to your agent

The Sequel CLI installs PostgreSQL into your coding agent in one step — it signs you in, provisions a scoped API key, and writes the right config to the right place. No keys to copy by hand.

Prefer npm? npm install -g @sequelsh/cli@latest works too.

Frequently asked questions

How do I connect my PostgreSQL database?

Click 'New Connection', select PostgreSQL, and enter your host, port, database name, username, and password. Sequel will test the connection before saving. Make sure your database allows connections from Sequel's IP range.

Is my database connection secure?

All connections use SSL/TLS by default. Credentials are encrypted at rest and never exposed in query results or logs. Sequel uses a read-only connection by default and will not execute write statements.

Can Sequel modify my data?

No. Sequel is read-only by default and will warn you if a query could modify data. The agent is explicitly instructed never to run INSERT, UPDATE, DELETE, or DDL statements unless you explicitly request and confirm it.

What PostgreSQL versions are supported?

Sequel supports PostgreSQL 12 and above. Older versions may work but are not officially tested.

Can I connect a cloud-hosted PostgreSQL database?

Yes. AWS RDS, Supabase, Railway, Neon, Google Cloud SQL, and other cloud PostgreSQL providers all work. You may need to allow Sequel's IP in your database firewall rules.

Does Sequel understand my schema automatically?

Yes. When you connect, Sequel reads your table names, column names, types, and relationships. It uses this schema to write accurate SQL and avoid hallucinated column names.
