Does my friend need an account for a group event?

No. One link, they answer yes/no/maybe.

Do you read my calendar?

Free/busy only. Never event titles.

Two assistants, one plan

You do not merge the two apps. Each person keeps their assistant. HoneyMatcha is the shared layer. Sage is optional.

Same MCP URL for both. Approve in your own browser, never as the agent. Then connect the two people so the agents can compare availability.
