Once connected, Zed’s Agent Panel can pull data from any Quadratic sheet, run Python and SQL, write formulas, and build charts, directly alongside your code and terminal.

## How to add Quadratic MCP to Zed

1.

### Open your Zed settings.json

In Zed, open the command palette with Cmd/Ctrl + Shift + P and run `zed: open settings`. This opens `~/.config/zed/settings.json` (macOS/Linux) or `%APPDATA%\Zed\settings.json` (Windows).

2.

### Add the Quadratic server under context_servers

Merge the snippet below into your settings. If you already have a `context_servers` block, add the `quadratic` entry to it.

```json
{
     "context_servers": {
       "quadratic": {
         "url": "https://mcp.quadratichq.com/"
       }
     }
}
```

3.

### Save and open the Agent Panel

Save `settings.json`. Open the Agent Panel with Cmd/Ctrl + Shift + A or the `agent: open agent panel` command.

4.

### Authorize with Quadratic

Zed will prompt you to authenticate the Quadratic MCP server. Click Authenticate and complete the Quadratic OAuth flow in your browser.

5.

### Use Quadratic in the Zed Agent

In the Agent Panel, mention Quadratic by name in a prompt, for example: "Using Quadratic, refresh my Q3 sales dashboard and tell me what changed."

## Using an older Zed build without native remote MCP?

If your version of Zed doesn't yet support remote MCP servers natively, use the `mcp-remote` bridge to proxy over stdio. Paste the snippet below into `settings.json` instead of the URL-only entry.

```json
{
  "context_servers": {
    "quadratic": {
      "source": "custom",
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.quadratichq.com/"],
      "env": {}
    }
  }
}
```

## Zed + Quadratic MCP FAQs

### Does Zed support remote MCP servers natively?

Recent Zed releases (v0.226+) support remote MCP servers via URL in `context_servers`. On older releases you need the `mcp-remote` stdio bridge shown in the advanced section above.

### Where is Zed’s settings.json?

macOS/Linux: `~/.config/zed/settings.json`. Windows: `%APPDATA%\Zed\settings.json`. The Zed command palette action "zed: open settings" will open it in the editor.

### The MCP server shows as timed-out in Zed. What now?

Make sure the entry in `context_servers` uses "url" for the remote Quadratic server and that the server name doesn’t contain spaces. If issues persist, switch to the `mcp-remote` bridge config in the advanced section.

### Can I configure which Quadratic tools Zed is allowed to call?

Yes. Zed’s Agent Panel has a profile system where you can enable/disable individual tools per profile. See the Zed docs for agent profiles.

### What is the Quadratic MCP URL?

The Quadratic MCP server is hosted at https://mcp.quadratichq.com/. Paste this URL into your Zed MCP configuration.

### Is Quadratic MCP free?

Yes. Quadratic MCP is included with every Quadratic plan, including the free tier. You only need a Quadratic account and a supported AI client.

### Is it secure?

Yes. Quadratic MCP uses OAuth 2.0 to authenticate each AI client with your Quadratic account. Your AI only sees files and data you already have access to, and you can revoke any connected client at any time in Quadratic settings.

### What can I do with Quadratic MCP in Zed?

Once connected, Zed can read values from your Quadratic sheets, write cells and formulas, run Python and SQL, and build charts. Ask Zed any question about your spreadsheets the same way you’d ask about a PDF or URL.

### Which other AI clients support Quadratic MCP?

Cursor, VS Code, Claude, ChatGPT, and Windsurf all work with Quadratic MCP today, plus any other client that supports remote Streamable HTTP MCP servers. [See the full list](/content/ai/mcp/index.html).
