The customer is building an AI-powered chat interface using the Document360 MCP server as the knowledge backend. The interface is intended to serve multiple end users who are not Document360 project members. The current OAuth flow requires each user to have a Document360 account and active project membership, which blocks this use case entirely.

Customer's ask is the support for secret key / API token based authentication on the MCP server, allowing their backend service to connect to MCP without per-user login.
