Use the available browser boundary
Ask Muse to open Corvio in its browser and sign in on the Corvio page. Keep credentials in the login surface, use the narrowest Workspace needed, and approve meaningful changes before Muse submits them.
This browser route can operate Corvio's normal UI, but it is not equivalent to a native MCP connection, a managed plugin, or a Corvio mailbox listener.
Do not confuse Muse with Muse Code
Muse Code has documented Agent Skill discovery, Streamable HTTP MCP, OAuth login, and headless execution. The hosted Muse product has a different extension surface. Install Skill + MCP in Muse Code only; do not infer that installation reaches Muse personal tasks.
Completion boundary
For browser use, verify the intended Corvio page and the final readback in the same Muse task. Do not expose Muse as an @-mention target unless a future integration provides a durable inbound event listener with authenticated delivery receipts.
