# Devin

Devin reads remote MCP servers from the MCP Marketplace in Settings. Add Cakewalk's gateway as a workspace-level entry; an organization admin authenticates once and Cakewalk's tools become available to every Devin session in the org.

## Requirements

* Organization admin role in Devin. Only organization admins can authenticate OAuth-based MCP servers.

## Install Method

Custom form in **Settings > MCP Marketplace**. Devin shares OAuth credentials across the organization, so the admin authenticates once on behalf of the workspace.

## Step 1: Open the MCP Marketplace

1. Open Devin and sign in as an organization admin.
2. Go to **Settings**.
3. Open **MCP Marketplace**.

## Step 2: Add Your Own Server

1. Click **Add Your Own** at the top of the page.
2. Fill the form:
   * **Server Name:** Cakewalk
   * **Icon:** optional emoji or URL.
   * **Short Description:** optional.
3. Select transport type **HTTP**.
4. In **Server URL**, paste:

   ```
   https://mcp-gateway.getcakewalk.io/mcp
   ```
5. Set authentication to **OAuth**.
6. Click **Save**.

## Step 3: Authenticate

After saving, click **Test listing tools**. Devin prompts you to complete the OAuth flow in your browser. Sign in with your Cakewalk account and approve the Connection. Devin stores the credentials on the workspace; every Devin session in the org reuses them.

## Verifying It Works

The **Test listing tools** action returns the tools surfaced through the Cakewalk gateway. In Cakewalk, the Devin card on **My Agents** flips to **Connected** after the first agent call.

## Workspace Scope

OAuth-based MCP servers in Devin are shared within the organization. Adding Cakewalk once authenticates every member's Devin sessions. Member-level revocation happens in Cakewalk's admin app, not in Devin.

## Troubleshooting

* **Add Your Own button is missing:** confirm your account has organization admin role. Non-admins cannot add OAuth-based MCP servers.
* **Test listing tools returns empty:** confirm the OAuth flow completed (the entry shows Connected). If still empty, check the Server URL has no trailing slash or path beyond `/mcp`.
