## 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 2026-10-04.

- **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**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 429 tokens (~214/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.

## MCP tools (2)

### `search_plants` (~140 tokens)

Search wholesale plants

Search Australia's live wholesale plant market: which wholesale growers list a plant, in which pot sizes, and from what trade price (AUD, ex GST). Use it for "who grows X" or "what does X cost wholesale". Botanical or common names both work.

Input parameters:

- `query` (string, required): Plant name, botanical or common, e.g. 'Lomandra Tanika' or 'lilly pilly'.
- `size` (string): Optional pot size, e.g. 140mm, 45L or Tube.
- `state` (string): Optional state or province code to limit growers, e.g. QLD, NSW, FL.

### `price_plant_list` (~159 tokens)

Price a plant list

Price a whole plant list or planting schedule from wholesale growers' live stock lists: each line matched to a grower, size and trade price, with the growers near the job preferred. Returns the priced lines and a link to the priced list on HortOS, which the person opens, checks and sends themselves. This tool does not place an order.

Input parameters:

- `job` (string): Optional: a name for the job or site.
- `list` (string, required): The plant list as text, one plant per line with quantity, name and pot size, e.g. '40 x Lomandra Tanika 140mm'.
- `near` (string): Optional: the job's suburb, town or postcode, so growers near the job are used.
