How it works

Three steps to get started

Connect PostgreSQL to Sequel

In your Sequel dashboard, go to Connections and add PostgreSQL. Sequel handles authentication and schema discovery automatically.

Add the MCP config

Copy the Sequel MCP configuration into VS Code's settings file (shown below). Swap in your API key from Settings → API Keys.

Ask VS Code about your data

Restart VS Code and start asking questions. "How many rows are in each table?" — and get a real answer backed by live PostgreSQL data.

Configuration

Add Sequel to VS Code

Place this in .vscode/mcp.json and replace sql_your_api_key with a key from Settings → API Keys.

.vscode/mcp.json

{
  "servers": {
    "sequel": {
      "url": "https://api.sequel.sh/mcp",
      "type": "http",
      "headers": {
        "Authorization": "Bearer sql_your_api_key"
      }
    }
  }
}

Sequel CLI

Install PostgreSQL MCP to VS Code

The Sequel CLI installs PostgreSQL into VS Code 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 PostgreSQL to VS Code?

You need two things: (1) connect PostgreSQL to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to VS Code using the setup shown above. Once both are done, VS Code can query your PostgreSQL data directly.

What PostgreSQL data can VS Code access?

VS Code can access any data available through your PostgreSQL connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.

Is my PostgreSQL data sent to VS Code's servers?

Query results are returned to VS Code as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.

Do I need a Sequel account?

Yes. You need a Sequel account to connect PostgreSQL and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to PostgreSQL and generate an API key from Settings → API Keys.

Can I connect multiple PostgreSQL accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple PostgreSQL accounts or properties, add each as a separate connection in Sequel. VS Code will be able to query all of them.
