Alex Gercog 0f618d8efb fix(mcp): use native HTTP for Devin MCP connections (#51646)
## 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.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
