You can use Tidewave with Zed. First, you must install a mcp-proxy.

Once that's done, open up the Assistant tab and click on the icon at the top right (see image below):

Zed AI panel

In the new pane, select "Add Custom Server" to open a new dialog. Fill in with the following.

On macOS/Linux:

{
  "tidewave-mcp": {
    "command": "/path/to/mcp-proxy",
    "args": ["http://localhost:$PORT/tidewave/mcp"],
    "env": {}
  }
}

On Windows:

{
  "tidewave-mcp": {
    "command": "c:\path\to\mcp-proxy.exe",
    "args": ["http://localhost:$PORT/tidewave/mcp"],
    "env": {}
  }
}

Where $PORT is the port your web application is running on and /path/to/mcp-proxy should be replaced with the absolute path to your mcp-proxy executable.

And you are good to go! Now Zed will list all tools from Tidewave available. If your application uses a SQL database, you can verify it all works by asking it to run SELECT 1 as database query. If it fails, check out our MCP Troubleshooting guide. You can also manage your installation, by clicking on the same icon and then on "Settings".
