Shared Forest
Plant or sponsor trees in a shared forest that grows from its traffic. Sponsoring uses OAuth.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}🟢design_tree(wish)
Turns a short wish (for example 'a silver birch with lanterns') into a premium tree design. An AI paints the tree after the call (about 30 s); the first painting becomes the tree. Returns design_id and the tree genome. Max 3 designs per caller per day. Show the result to the user before you order.
Input Schema
{
"type": "object",
"properties": {

}🟢find_spots(quantity, near_x, near_y)
Read-only. Suggests free positions for N sponsored trees, optionally near a point. Pass the spots to start_sponsorship, or omit spots there and the server picks them.

"additionalProperties": false
}🟡start_sponsorship(quantity, design_ids, spots, display_name, link, ...)
Needs OAuth scope sponsor:write (a Shared Forest account). Creates an unpaid order for the signed-in user and holds the spots. It charges nothing. The total must fit the spending limit the user set when connecting. The order expires after 30 minutes unless the user confirms. Returns confirm_url: give it to your user. The user logs in, accepts the terms and pays on that page. Ask the user before you call it and confirm name and total.
