MCP: Claude Desktop Setup

Before getting started, ensure you have the following:

• Node must be downloaded in order to use Transcend's MCP.
• Claude Desktop.
• OAuth Client configured here.
  • The redirect URI must be http://127.0.0.1:{port}/callback.

Claude Desktop reads from:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\\Claude\\claude_desktop_config.json

In Claude Desktop, select Settings

Select Developer

Right click claude_desktop_config.JSON and select a text editor (in the case of Mac, select TextEdit).

In the text editor, paste the definition from the package’s readme to the JSON found here (or copy the below snippet)

{
  "mcpServers": {
    "transcend": {
      "command": "npx",
      "args": ["-y", "@transcend-io/mcp"],
      "env": {
        "TRANSCEND_OAUTH_CLIENT_ID": "your-client-id",
        "TRANSCEND_OAUTH_CLIENT_SECRET": "your-client-secret",
        "TRANSCEND_OAUTH_REDIRECT_PORT": "your-client-redirect-port"
      }
    }
  }
}

Your config should show a successful run when ready. You must fully quit Claud Desktop and re-open in order to use the Transcend MCP.

# macOS
open -a "Cursor" ~/Library/Application\ Support/Claude/claude_desktop_config.json

If the file doesn't exist, create it with the contents below.

{
  "mcpServers": {
    "transcend": {
      "command": "npx",
      "args": ["-y", "@transcend-io/mcp"],
      "env": {
        "TRANSCEND_OAUTH_CLIENT_ID": "your-client-id",
        "TRANSCEND_OAUTH_CLIENT_SECRET": "your-client-secret",
        "TRANSCEND_OAUTH_REDIRECT_PORT": "your-client-redirect-port"
      }
    }
  }
}

Fully quit (cmd+Q on Mac) and reopen. Confirm the connection in Settings → Developer — transcend should appear with a tool count.
