## About

Connects to the authorized.by registry of retailers that brands (manufacturers) have explicitly authorized to sell their products. You can search brands and retailers, list a brand's authorized shops, list the brands a shop is authorized for, and check a single shop by domain against a brand or a product GTIN. Results include public certificate links.

The server is hosted at a remote streamable HTTP endpoint. No sign-in, account or API key is needed. All tools are read-only, and the rate limit is 20 requests per minute per IP address. Results only cover authorizations registered on authorized.by, so a missing record does not prove a shop is unauthorized.

## What it can do

- Search brands registered on authorized.by
- Get a brand's public profile
- List all retailers authorized by a brand
- Search retailers by name, alias or shop domain
- List the brands a retailer is authorized to sell
- Verify a shop's authorization by brand or product GTIN
- Return public certificate links as proof

## Tools (7)

- `get_brands`: Search brands registered on authorized.by or list them all, with pagination. (read-only)
- `get_brand`: Get a brand's public profile: categories, website, country, description and retailer count. (read-only)

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http authorized-by https://app.authorized.by/api/public/mcp
```

2. Start Claude Code and type `/mcp`. **authorized-by** should show as connected.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **authorized.by** and paste this URL:

```url
https://app.authorized.by/api/public/mcp
```

3. Click **Add**. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=authorized.by&connectorUrl=https%3A%2F%2Fapp.authorized.by%2Fapi%2Fpublic%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://app.authorized.by/api/public/mcp` and click **Add**.

3. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://app.authorized.by/api/public/mcp` as the server URL, then for authentication choose **No authentication**.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=authorized-by&config=eyJ1cmwiOiJodHRwczovL2FwcC5hdXRob3JpemVkLmJ5L2FwaS9wdWJsaWMvbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "authorized-by": {
      "url": "https://app.authorized.by/api/public/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=authorized-by&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fapp.authorized.by%2Fapi%2Fpublic%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"authorized-by","type":"http","url":"https://app.authorized.by/api/public/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "authorized-by": {
      "type": "http",
      "url": "https://app.authorized.by/api/public/mcp"
    }
  }
}
```

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "authorized-by": {
      "serverUrl": "https://app.authorized.by/api/public/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add authorized-by --url https://app.authorized.by/api/public/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.authorized-by]
url = "https://app.authorized.by/api/public/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http authorized-by https://app.authorized.by/api/public/mcp
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "authorized-by": {
      "type": "http",
      "url": "https://app.authorized.by/api/public/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://app.authorized.by/api/public/mcp`.
