Sequel

How to Connect PostgreSQL to Zed

Query your PostgreSQL data directly from Zed using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.

Short answer

Connect PostgreSQL to Sequel, then add Sequel's MCP server to Zed using the config on this page. Zed can then query your live PostgreSQL data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.

Example prompts

Everything you can ask Zed about your PostgreSQL data.

Ask in plain English — Sequel translates it into a PostgreSQL query, runs it, and Zed hands back the answer. No SQL, no dashboards, no CSV exports.

What you can ask Zed
  • How many rows are in each table?
  • Show me the 10 most recently created users
  • What's the average order value by customer segment?
  • Which products have never been ordered?
  • Show me monthly revenue broken down by plan type

How it works

Three steps to get started

1

Connect PostgreSQL to Sequel

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

2

Add Sequel to the agent

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

3

Ask Zed about your data

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

Why Zed

What Zed does with your PostgreSQL data

Fast editor, full data access

Zed is built for speed. Adding Sequel means you get low-latency data access alongside Zed's fast editing experience — no lag, no context switching.

Schema context for better code

Zed's AI can pull your actual database schema through Sequel and use it to generate accurate SQL, TypeScript types, and ORM models — not guesses based on training data.

Collaborative data exploration

With Zed's multiplayer editing, your whole team can share a session and explore data together. One person queries through Sequel; everyone sees the result.

Configuration

Add Sequel to Zed

Place this in ~/.config/zed/settings.json and replace sql_your_api_key with a key from Settings → API Keys.

~/.config/zed/settings.json

{
  "context_servers": {
    "sequel": {
      "url": "https://api.sequel.sh/mcp",
      "settings": {
        "headers": {
          "Authorization": "Bearer sql_your_api_key"
        }
      }
    }
  }
}

Install

Install PostgreSQL MCP in Zed

Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.

Frequently asked questions

How do I connect PostgreSQL to Zed?

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

What PostgreSQL data can Zed access?

Zed 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 Zed's servers?

Query results are returned to Zed 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. Zed will be able to query all of them.

How do I add Sequel to Zed?

Open Zed settings (Cmd+, on macOS), find the `context_servers` key, and add the Sequel configuration shown above. Restart Zed for changes to take effect.

Which Zed AI features work with Sequel MCP?

Sequel tools are available in Zed's AI panel (Assistant). You can call them from the chat interface. Support for additional Zed AI features depends on Zed's MCP integration updates.

Does Zed support HTTP MCP servers?

Yes, Zed supports MCP over HTTP (Streamable HTTP transport). The Sequel MCP endpoint uses this transport, so no extra configuration is needed.

Can I use Sequel MCP in Zed's multiplayer sessions?

MCP tools in Zed are currently per-user — each collaborator connects with their own API key. Tool call results are visible to all participants in a shared session.

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.
