MCP Addon Tools and Resources

This page covers MCP tools and resources that require specific addons to be enabled on your TREK instance. For the rest of the surface (trips, places, day planning, accommodations, transport, reservations, tags, maps, and notifications — plus the Budget tools, which need the Budget addon but are documented there) see MCP-Tools-and-Resources.

unmark_country_visited	Remove a country from your visited list.

delete_bucket_list_item	Remove an item from your bucket list.

Collab (Collab addon required)

Requires collab:read or collab:write scope.

The addon alone is not enough. Collab has four sub-features an admin switches on and off independently in Admin → Addons — Notes, Polls, Chat and What's Next, all on by default — and three of them gate MCP entries. A tool or resource is only registered when its own sub-feature is enabled on top of the addon, so switching one off makes its entries vanish from the tool list rather than return an error. What's Next has no MCP tools or resources of its own, so toggling it changes nothing here.

Sub-feature	Tools it gates	Resource it gates
Notes	create_collab_note, update_collab_note, delete_collab_note	trek://trips/{tripId}/collab-notes
Polls	list_collab_polls, create_collab_poll, vote_collab_poll, close_collab_poll, delete_collab_poll	trek://trips/{tripId}/collab/polls
