Setup

WRITER’s MCP server uses OAuth 2.1 with PKCE and dynamic client registration, so there is nothing to register and no client ID or secret to configure.

1. Install the plugin.
2. Complete the WRITER OAuth login in the browser when your client prompts.
3. Tool calls run with your own WRITER permissions: you see the playbooks and deliverables your WRITER seat can access.

Access requirements:

• A WRITER account with a seat in an organization enrolled in the Playbooks and deliverables closed beta.
• The server requests the mcp:playbooks and mcp:deliverables scopes. Clients that discover scopes from the OAuth metadata get these automatically.
• Access tokens last one hour and refresh automatically; you may be asked to sign in again after a day.
• Requests are rate limited per organization.
