How to Connect Cloudflare D1 to Zed

Query your Cloudflare D1 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 Cloudflare D1 to Sequel, then add Sequel's MCP server to Zed using the config on this page. Zed can then query your live Cloudflare D1 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 Cloudflare D1 data.

Ask in plain English — Sequel translates it into a Cloudflare D1 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 20 most recently created users.
  • What is the conversion rate from signup to first purchase, by month?
  • Which customers signed up last quarter and are still active?
  • Find duplicate email addresses in the users table.

How it works

Three steps to get started

1

Connect Cloudflare D1 to Sequel

In your Sequel dashboard, go to Connections and add Cloudflare D1. 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 Cloudflare D1 data.

Why Zed

What Zed does with your Cloudflare D1 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 Cloudflare D1 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 Cloudflare D1 to Zed?

You need two things: (1) connect Cloudflare D1 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 Cloudflare D1 data directly.

What Cloudflare D1 data can Zed access?

Zed can access any data available through your Cloudflare D1 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 Cloudflare D1 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 Cloudflare D1 and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Cloudflare D1 and generate an API key from Settings → API Keys.

Can I connect multiple Cloudflare D1 accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Cloudflare D1 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 does Sequel connect to Cloudflare D1?

Through Cloudflare's D1 REST API. You sign in with Cloudflare, approve the connection, and choose which D1 database to connect. Sequel stores the resulting tokens encrypted and refreshes them automatically, so there is no API token to create, paste, or rotate by hand.

Can one connection reach more than one database?

No. You pick exactly one D1 database when you connect, and that choice is baked into the connection. Sequel has no tool that can list or query any other database. If you want to query a second database, add a second connection.

Is it read-only?

Yes, and it is enforced by Cloudflare rather than by us. Sequel requests only the D1 Read scope, so Cloudflare itself rejects any write that reaches the D1 API. The tools Sequel exposes are query and schema introspection, and nothing in the connector can create, update, or delete data.

Do I need to move my data anywhere?

No. Sequel queries D1 directly over Cloudflare's API. Nothing is copied into a warehouse and there is no sync to schedule. Query results are stored so you can export them, but your tables stay where they are.
