Zed

Zed supports MCP servers through its context_servers setting. Configuration is global — Zed does not currently support per-project MCP config files.

No credentials are required in the config. Calling login opens a browser to Perfai’s own sign-in page (OAuth) and completes automatically — see Login below.

Installation

macOS
Linux
Windows

File: ~/.config/zed/settings.jsonAdd (or merge) the following into your existing settings:

{
  "context_servers": {
    "perfai-cloud-mcp": {
      "command": {
        "path": "npx",
        "args": ["-y", "perfai-cloud-mcp"]
      }
    }
  }
}

File: ~/.config/zed/settings.json

{
  "context_servers": {
    "perfai-cloud-mcp": {
      "command": {
        "path": "npx",
        "args": ["-y", "perfai-cloud-mcp"]
      }
    }
  }
}

File: %APPDATA%\Zed\settings.json

{
  "context_servers": {
    "perfai-cloud-mcp": {
      "command": {
        "path": "cmd",
        "args": ["/c", "npx", "-y", "perfai-cloud-mcp"]
      }
    }
  }
}

Windows needs the cmd /c wrapper because npx is a .cmd shim, not a real executable — without it you’ll see spawn npx ENOENT.

Zed’s context_servers format uses a nested command object with path and args — this differs from the flat command / args format used by Cursor and Claude Code. If you prefer not to use the browser login, create a Perfai API key and add "env": { "PERFAI_API_KEY": "pfk_xxxxxxxxxxxx_..." } alongside path/args — keep settings.json private if you do.

Open settings in Zed

You can open settings.json directly from Zed:

Press Cmd+, (macOS) or Ctrl+, (Linux/Windows).
Click Open settings.json in the top-right corner of the settings panel.
Add the context_servers block and save.

Zed picks up the change immediately — no restart required.

Verify the server is connected

Open the AI panel in Zed (click the AI icon or press Cmd+?).
Look for perfai-cloud-mcp in the context server list.
A green dot means it’s running. If it shows red, check that Node.js 18+ is installed and npx is on your PATH.

The prompts below run inside Zed’s AI assistant panel, not your terminal. The only terminal/file steps are editing settings.json.

In Zed’s AI assistant, type:

Login to Perfai

This opens a browser to Perfai’s sign-in page (or uses PERFAI_API_KEY if you set it). Confirm with:
