Editorial interest 79/100 Selection signal · not a rating of the site

CohostSTR is a free, open-source MCP connector that lets AI assistants handle guest messages, pricing, calendar changes, and other Guesty tasks.

Landing page captured for the 2026-09-25 issue.

For: Guesty hosts using Claude or another MCP client
Worth noticing: It holds messages containing phone numbers, email, off-platform payment, or direct-booking nudges before sending.

Field notes

The workflow is framed as an on-demand assistant on the host’s computer, rather than an autonomous service running in the background. The page says guest replies can draw on listing details such as check-in times and house rules, and that messages with off-platform contact or payment prompts are held before sending. Paid setup kits are listed in two tiers based on the number of listings.
