Install Django Chainsaw in Devin Desktop

What you need first

• Devin Desktop, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_DJANGO_CHAINSAW_PROJECT_PATH,YOUR_DJANGO_CHAINSAW_SETTINGS_MODULE.

Steps

1. Open ~/.config/devin/mcp_config.json, or create it. On Windows it is %APPDATA%\devin\mcp_config.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "django-chainsaw-mcp": {
      "command": "uvx",
      "args": ["django-chainsaw-mcp==0.1.5"],
      "env": { "DJANGO_CHAINSAW_PROJECT_PATH": "YOUR_DJANGO_CHAINSAW_PROJECT_PATH", "DJANGO_CHAINSAW_SETTINGS_MODULE": "YOUR_DJANGO_CHAINSAW_SETTINGS_MODULE" }
    }
  }
}

3. Replace YOUR_DJANGO_CHAINSAW_PROJECT_PATH,YOUR_DJANGO_CHAINSAW_SETTINGS_MODULE with your own values.
4. Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of django-chainsaw-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Devin Desktop sees. Install it, or write the full path of uvx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
