Airbnb Co-Hosting at Scale: An MCP Agent That Opens 30 Owner Accounts Without Mixing Them

Description and use

In large‑scale Airbnb co‑hosting, 30 owners generate over 180 logins across multiple tools. The solution uses a dedicated BitBrowser profile per owner and an MCP agent that opens the correct profile based on a daily PMS digest. This isolates cookies, prevents mistakes, and complies with Airbnb’s terms.

Problem

Co‑hosts managing dozens of owners face a login pile‑up: each owner has multiple external tools (smart lock, Booking.com, city portals, etc.), leading to 180+ simultaneous logins that mix cookies, autofill and tabs, risking wrong door codes and data leaks.

Outcome

The workflow isolates each owner’s logins in separate browser profiles, eliminates cross‑owner cookie leakage, and automates workspace selection based on a daily digest, thereby reducing mistakes and staying within Airbnb’s terms.

Workflow

• 1. Create a BitBrowser profile per owner and one HQ profile for the co‑host’s Airbnb session.
• 2. Store each owner’s external logins (smart lock, Booking.com, registration portals, statements folder) in the owner profile’s saved passwords.
• 3. Configure start pages for each profile to open the owner’s tools directly.
• 4. Use a naming scheme (e.g., OWN‑017 Harbor View) and tags (lock, booking, registration) to group profiles by city or team.
• 5. Enable BitBrowser Local API and generate an MCP token.
• 6. Configure the MCP client with the BitBrowser MCP endpoint and token.
• 7. Write a short script that pulls a morning digest (arrivals, unanswered threads, calendar gaps) from a PMS API into digest.json.
• 8. Run an MCP agent (Claude, Cursor, Codex, etc.) that reads digest.json, selects owners needing attention, and calls BitBrowser MCP tools to list, open, tile, and close profiles.
• 9. The agent opens the required owner profile, tiles it on screen, and hands control to the co‑host to answer guests.
• 10. The agent tracks which workspace is open and closes it when the co‑host signals completion.

Evidence

Separate browser profiles, one per owner, fix the pile without anything clever. Each profile has its own cookie jar, its own saved logins, its own start pages and its own history.

The agent handles the bookkeeping of which workspace is open. People handle the guests.
