## Problem
The Devin Desktop preset wraps Supabase MCP URLs in `npx -y mcp-remote`,
although Devin Local and Devin CLI support Streamable HTTP natively.
Connecting therefore adds a Node/npm bridge that the client does not
need. The preset also lacks Devin-specific setup and authentication
instructions.
## Solution
Use the existing native `url` configuration for Devin:
```json
{
"mcpServers": {
"supabase": {
"url": "https://mcp.supabase.com/mcp"
}
}
}
```
The generated URL retains the selected project, read-only mode, and
features. The internal `windsurf` key is preserved.
Add shared setup instructions for the configuration panel and generated
Markdown: user-scope installation, the Windows config file location next
to the shared macOS/Linux one, a re-authentication command for hosted
connections, and loading tools in a new Devin Local or CLI session.
Local connections omit the re-authentication step.
Include Devin in the shared client URL round-trip test. The Devin-only
test files from the first revision were removed in review so that tests
stay shared across clients.
Native configuration follows the official [Devin MCP
documentation](https://docs.devin.ai/cli/extensibility/mcp/configuration)
and [Devin Local
integration](https://docs.devin.ai/desktop/devin-local).
## Validation
- **273 tests passed** across 28 `ui-patterns` test files on the current
revision; 34 of them in the MCP section.
- Package typechecking, Prettier on the four changed files, and `git
diff --check` passed.
- **Devin CLI 3000.11.3:** native HTTP initialization and tool
discovery; synthetic OAuth with S256 PKCE and authenticated tool
discovery using a saved token.
- **Devin Desktop 3.10.48 / bundled Devin Local 3000.10.48:** the server
card showed `Connected` and the fixture tool. Its `tools/list` request
came from the bundled Devin Local process.
OAuth validation used controlled local fixtures; live Supabase Hosted
authorization was not exercised. The full monorepo application build was
not run.
## Review instructions
1. Run `pnpm --filter ui-patterns exec vitest run src/McpUrlBuilder` and
`pnpm --filter ui-patterns typecheck`.
2. Select **Devin Desktop** in the MCP configuration panel. Confirm that
the JSON uses `url` and preserves the selected project, read-only mode,
and features.
3. Switch to the local connection. Confirm that Hosted login
instructions disappear. Check that generated Markdown explicitly limits
that login step to Hosted connections.

component and its generated instructions.
