WHAT IT DOES

What appflowy_login does on AppFlowy MCP

WHY IT NEEDS A POLICY

Why appflowy_login needs a policy

Login establishes an authenticated session and stores tokens server-side, which is a state-modifying operation (creating/persisting a session). It is not purely a read operation since it writes authentication tokens. It is not destructive or financial. Severity is medium because misuse could result in unauthorized session establishment or credential abuse, though tokens are not exposed in output.

From the tool's definition Login to AppFlowy. Tokens are stored in the server; they are not returned to avoid leaking credentials into tool output.
