## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-28.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 50/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1437 tokens (~102/item across 14 items; 13 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 15 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

First indexed and scored.

## MCP tools (13)

### `get_forest_stats` (~58 tokens)

Forest statistics

Read-only. Counts of trees, groves, total and unique visitors, and traffic by class (humans, agents, bots, trees planted today).

Input parameters:

- `fields` (array): Return only these counters. Omit for all counters.

### `get_forest` (~91 tokens)

Forest summary

Read-only. Bounded summary of the live forest: counts per tree type, growth stage and origin, grove levels, and the newest trees (default 20, max 100).

Input parameters:

- `bbox` (array): Bounding box [minX, minY, maxX, maxY] in world coordinates. Only trees inside it are returned.
- `limit` (integer): Number of newest trees to return.

### `list_trees` (~106 tokens)

List trees

Read-only. One page of trees with cursor pagination, the same data as GET /api/forest?limit=. Pass nextCursor as cursor until it is null.

Input parameters:

- `bbox` (array): Bounding box [minX, minY, maxX, maxY] in world coordinates. Only trees inside it are returned.
- `cursor` (string): Opaque cursor from nextCursor of the previous page.
- `limit` (integer, required): Trees per page, for example 100.

### `plant_tree` (~85 tokens)

Plant a tree

Plant one tree in the Shared Forest for the caller. One tree per visitor per day; repeats only add growth energy. The visit counts as agent traffic. Ask the user before you call it.

Input parameters:

- `idempotency_key` (string): Optional retry key, for example a UUID. A retry with the same key within 24 hours returns the first visitId and plants nothing new.

### `explain_shared_forest` (~64 tokens)

Explain Shared Forest

Read-only. Returns the full agent guide as Markdown: growth rules, API, tools and limits.

Input parameters:

- `section` (string): Return only the section whose heading contains this text, for example 'Limits' or 'MCP tools'. Omit for the whole guide.

### `get_price_quote` (~66 tokens)

Quote a tree sponsorship

Read-only. Final price for sponsoring N trees for 12 months: unit price, total in euro cents and discount. Call it before you tell the user a price.

Input parameters:

- `quantity` (integer, required): Number of trees, 1-100. Larger orders get a lower unit price.

### `design_tree` (~104 tokens)

Design a sponsored tree

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 parameters:

- `wish` (string, required): What the tree should look like, 1-200 characters. No brands, logos or text.

### `get_design` (~47 tokens)

Read a tree design

Read-only. Returns one design by design_id: genome, genomeHash and expiresAt.

Input parameters:

- `design_id` (string, required): Design id from design_tree, for example dsn_abc123.

### `find_spots` (~116 tokens)

Find free spots

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.

Input parameters:

- `near_x` (number): Optional x coordinate (0-8192) to search near. Needs near_y.
- `near_y` (number): Optional y coordinate (0-8192) to search near. Needs near_x.
- `quantity` (integer, required): Number of trees, 1-100. Larger orders get a lower unit price.

### `start_sponsorship` (~302 tokens)

Start a tree sponsorship

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.

Input parameters:

- `design_ids` (array, required): One design_id for all trees, or one per tree.
- `display_name` (string, required): Name shown on the trees, 1-32 characters, labelled Sponsored.
- `email` (string): Optional email for the confirmation and the invoice. Default: the email of the signed-in account.
- `idempotency_key` (string, required): Retry key, for example a UUID. A retry with the same key returns the same order.
- `link` (string): Optional https link. It goes live after manual review.
- `link_text` (string): Optional public label for the link. Requires link; approved with it.
- `quantity` (integer, required): Number of trees, 1-100. Larger orders get a lower unit price.
- `short_description` (string): Optional short public description. Requires link; approved with it.
- `spots` (array): Optional positions from find_spots, one per tree. Omit and the server picks free spots.

### `get_order` (~88 tokens)

Read a sponsorship order

My sponsorship orders

Read-only. Needs OAuth scope account:read. The signed-in user's sponsorship orders, newest first, with status, total and tree ids.

Input parameters:

- `limit` (integer): Number of orders, 1-50.

### `my_trees` (~54 tokens)

My sponsored trees

Read-only. Needs OAuth scope account:read. The trees of the signed-in user's fulfilled orders, with a link to each tree in the forest.

### Is the Shared Forest MCP server safe to use?

Shared Forest scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Shared Forest MCP server expose?

Shared Forest exposes 13 tools: get_forest_stats, get_forest, list_trees, plant_tree, explain_shared_forest, and 8 more. Their descriptions and schemas cost roughly 1,232 tokens of context every time the server is loaded.

### Does the Shared Forest MCP server require authentication?

No. We connected to Shared Forest without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Shared Forest MCP server still maintained?

Shared Forest is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
